Model 2285 Getting Started Guide
1 • Overview
Glossary
This section defines commonly used terms in this manual. These terms are related to Internetworking, and
defined in regards to their use with Model 2285.
MAC address
On a local area network or other network, the MAC (Media Access Control) address is the computer’s unique
hardware number. (On an Ethernet LAN, it is the same as the Ethernet address.)
It is a unique 12-digit hardware number, which is composed of 6-digit OUI (Organization Unique Identifier)
number and 6-digit hardware identifier number. The MAC address can be found on the bottom of the
original package.
Host
A user’s computer connected to the network
Internet protocol specifications define host as any computer that has full two-way access to other computers on
the Internet. A host will have a specific local or host number that, together with the network number, forms its
unique IP address.
Session
A series of interactions between two communication end points that occur during the span of a
single connection
Typically, one end point requests a connection with another specified end point. If the specified end point
replies, and agrees to the connection, the end points then take turns exchanging commands and data (talking to
each other). The session begins when the connection is established at both ends and terminates when the connection is ended.
Client/Server
Client/server describes the relationship between two computer programs in which one program, the client,
makes a service request from another program, the server, which fulfills the request.
A server is a computer program that provides services to other computer programs on one or many computers.
The client is the requesting program or user in a client/server relationship. For example, the user of a Web
browser is effectively making client requests for pages from servers all over the Web. The browser itself is a client in its relationship with the computer that is getting and returning the requested HTML file. The computer
handling the request and sending back the HTML file is a server.

Model 2285 Getting Started Guide 3 • Network configuration
IP configuration
The Model 2285 requires a valid IP address to operate within the user’s network environment. If the IP
address is not readily available, contact the system administrator to obtain a valid IP address for the Model
2285.
Note The Model 2285 requires a unique IP address to connect to the user’s net-
work.
The users may choose one of three Internet protocols in setting up the Model 2285 IP address: i.e.,
• Static IP
• DHCP (Dynamic Host Configuration Protocol)
The Model 2285 is initially defaulted to STATIC mode, with a static IP address of 192.168.161.5. Table 3
shows the configuration parameters for all three IP configurations. Figure 7 shows the actual web-based GUI to
change the user’s IP configuration.

Figure 7. IP configuration
Using a Static IP Address
When using a Static IP address, the user must manually specify all the configuration parameters associated with
the IP address of the Model 2285. These include the IP address, the network subnet mask, the gateway computer and the domain name server computers. This section will look at each of these in more detail.
Note The Model 2285 will attempt to locate all this information every time it is
turned on.
IP configuration 30
Model 2285 Getting Started Guide 3 • Network configuration
IP address
A Static IP address acts as a “static” or permanent identification number. This number is assigned to a computer to act as its location address on the network. Computers use these IP addresses to identify and talk to
each other on a network. Therefore, it is imperative that the selected IP address be both unique and valid in a
network environment.
Note 192.168.1.x will never be assigned by an ISP (Internet Service Provider). IP
addresses using this form are considered private. Actual applications of the
Model 2285 may require access to public network, such as the Internet. If so,
a valid public IP address must be assigned to the user’s computer. A public IP
address is usually purchased or leased from a local ISP.
Subnet mask
A subnet represents all the network hosts in one logical location, such as a building or local area network
(LAN). The Model 2285 will use the subnet mask setting to verify the origin of all packets. If the desired
TCP/IP host specified in the packet is in the same geographic location (on the local network segment) as
defined by the subnet mask, the Model 2285 will establish a direct connection. If the desired TCP/IP host
specified in the packet is not identified as belonging on the local network segment, a connection is established
through the given default gateway.
Default gateway
A gateway is a network point that acts as a portal to another network. This point is usually the computer or
computers that control traffic within a network or a local ISP (Internet service provider). The Model 2285 uses
the IP address of the default gateway computer to communicate with hosts outside the local network environment. Refer to the network administrator for a valid gateway IP address.
Primary and Secondary DNS
The DNS (Domain Name System) server is used to locate and translate the correct IP address for a requested
web site address. A domain name is the web address (i.e. www.yahoo.com) and is usually easier to remember.
The DNS server is the host that can translate such text-based domain names into the numeric IP addresses for
a TCP/IP connection.
The IP address of the DNS server must be able to access the host site with the provided domain name. The
Model 2285 provides the ability to configure the required IP addresses of both the Primary and Secondary
DNS servers addresses. (The secondary DNS server is specified for use when the primary DNS server is
unavailable.)
Using DHCP
Dynamic host configuration protocol (DHCP) is a communications protocol that lets network administrators
manage and automate the assignment of IP addresses centrally in an organization’s network. DHCP allows the
network administrator the ability to provise and distribute IP addresses from a central point and automatically
send a new IP address when a computer is plugged into a different network location.
When in static IP mode, the IP address must be entered manually at each computer. If a computer is moved to
another network location, a new IP address may need to be assigned. DHCP allows all the parameters, including the IP address, subnet mask, gateway and DNS servers to be automatically configured when the IP address
is assigned. DHCP uses a “lease” concept in assigning IP addresses to a computer. It limits the amount of time
a given IP address will be valid for a computer. All the parameters required to assign an IP address are automat-
IP configuration 31
Model 2285 Getting Started Guide 3 • Network configuration
ically configured on the DHCP server side, and each DHCP client computer receives this information when
the IP address is provided at its boot-up.
Each time the device is reset, the Model 2285 broadcasts a DHCP request over the network. The reply generated by the DHCP server contains the IP address, as well as the subnet mask, gateway address, DNS servers
and the “lease” time. The Model 2285 immediately places this information in its memory. Once the “lease”
expires, the Model 2285 will request a renewal of the “lease” time from the DHCP server. If the DHCP server
approves the request for renewal, the Model 2285 can continue to work with the current IP address. If the
DHCP server denies the request for renewal, the Model 2285 will start the procedure to request a new IP
address from the DHCP server.
Note While in DHCP mode, all network-related parameters for the Model 2285
are to be configured automatically, including the DNS servers. If the DNS
server is not automatically configured, the user may manually configure the
settings by entering the primary and secondary DNS IP addresses. To force
an automatic configuration of the DNS address, set the primary and secondary DNS IP addresses to 0.0.0.0 (recommended).
A DHCP sever assigns IP addresses dynamically from an IP address pool, which is managed by the network
administrator. This means that the DHCP client, i.e. the Model 2285, receives a different IP address each time
it boots up. The IP address should be reserved on the DHCP server side to assure that the user always knows
the newly assigned Model 2285 address. In order to reserve the IP address in the DHCP network, the administrator needs the MAC address of the Model 2285 found on the label sticker at the bottom of the Model 2285.

Model 2285 Getting Started Guide 3 • Network configuration
Figure 8. SNMP Configuration
SNMP configurations
The Model 2285 has the SNMP (Simple Network Management Protocol) agent supporting SNMP v1 and v2
protocols. Network managers like NMS or SNMP Browser can exchange information with Model 2285, as
well as access required functionality.
SNMP protocols include GET, SET, GET-Next, and TRAPs. With these functions, a manager can be notified
of significant events (TRAPs), query a device for more information (GET), and make changes to the device
state (SET). SNMPv2 adds a GET-Bulk function for retrieving tables of information and security functions.
With the SNMP configuration panel, the user can configure MIB-II System objects, access control settings and
TRAP receiver settings. The manager configured in this menu can perform both information exchange and
action control. Figure 8 shows a SNMP configuration screen via a web interface.
MIB-II System objects Configuration
MIB-II System objects configuration sets the System Contact, Name, Location, and Authentication-failure
traps used by the SNMP agent of the Model 2285. These settings provide the values used for the MIB-II sysName, sysContact, sysLocation, sysService and enableAuthenTrap.
Brief descriptions of each object are as follows:
• sysContact: Identification of the contact person for the managed system (Model 2285), and a description of
how to contact the person.
SNMP configurations 33
Model 2285 Getting Started Guide 3 • Network configuration
• sysName: Name used to identify the system. By convention, this is the fully qualified domain name of
the node.
• sysLocation: The physical location of the system (e.g., Room 384, Operations Lab, etc.).
• sysService (read only): A series of values, separated by commas, that indicate the set of services that the sys-
tem provides. By default, Model 2285 only supports an Application(7) service level.
• EnablePoweronTraps: Indicates whether the SNMP agent process is permitted to generate power-on traps.
• EnableAuthenTrap: Indicates whether the SNMP agent process is permitted to generate authentication-
failure traps. The value of this object overrides any configuration information; as such, it provides a means
whereby all authentication-failure traps may be disabled..
• EnableLoginTrap: Indicates whether the SNMP agent process is permitted to generate system login traps
for console, telnet and Web access.
If users need support for adding or modifying MIBs, please contact Patton technical support.
Note For more information about the MIBs and SNMP, see the RFCs 1066,
1067, 1098, 1317, 1318 and 1213.
Access Control Configuration
Access Control defines accessibility of managers to the Model 2285 SNMP agent. Only the manager set in this
menu can access Model 2285 SNMP agent to exchange information and control actions. If there is no specified IP address (all IP address are defaulted to 0.0.0.0), a manager from any host can access the Model 2285
SNMP agent.
Trap Receiver Configuration
The Trap receiver defines managers, which can be notified of significant events (TRAP) from the Model 2285
SNMP agent.

Figure 9. Browsing MIB-II OIDs of Model 2285 SNMP agent using SNMP Browser (AdventNet MibBrowser)
Management using SNMP
The Model 2285 can be managed through the SNMP protocol using NMS (Network Management System) or
SNMP Browser. Before using the NMS or SNMP Browser, the user must set the access control configuration
properly so that the Model 2285 permits host access where the NMS or SNMP Browser is executed. Figure 9
shows a screen shot of a typical SNMP browser with MIB-II OIDs of the Model 2285 SNMP agent.
Dynamic DNS Configuration
When users connect the Model 2285 to a DSL line or use a DHCP configuration, the IP address might be
changed whenever it reconnects to the network. It can therefore be very difficult to post all related contacts for
each new IP address. In addition, if the administrator only has access through the remote console, there is no
way to know if an IP address has changed, or what the new IP address is.
A Dynamic DNS service is provided by various ISPs or organizations to deal with the above issue. By using the
Dynamic DNS service, users can access the Model 2285 through the hostname registered in the Dynamic
DNS Server regardless of any IP address change.
Dynamic DNS Configuration 35
Model 2285 Getting Started Guide 3 • Network configuration
By default, the Model 2285 only supports Dynamic DNS service offered at Dynamic DNS Network Services,
LLC (www.dyndns.org). Contact Patton technical support for issues regarding other Dynamic DNS
service providers.
To use the Dynamic DNS service provided by Dynamic DNS Network Services, the user must set up an
account in their Members’ NIC (Network Information Center - http://members.dyndns. org). The user may
then add a new Dynamic DNS Host link after logging in to their Dynamic DNS Network Services
Members NIC.
After enabling the Dynamic DNS service in the Dynamic DNS Configuration menu, the user must enter the
registered Domain Name, User Name, and Password. After applying the configuration change, users can access
the Model 2285 using only the Domain Name.

Figure 11. SMTP Configurations
SMTP Configuration
The Model 2285 can be configured (see figure 11) to send an email notification when the number of system
log messages reaches to certain value and/or when an alarm message is created due to an issue with serial port
data. The user must configure a valid SMTP server send these automatically generated emails. The Model
2285 supports three SMTP server types:
• SMTP without authentication
• SMTP with authentication
• POP-before-SMTP
Figure 12. SMTP mode selection in SMTP configuration
These examples can be seen in figure 12. Required parameters for each SMTP configuration include:
• SMTP server IP address
• SMTP user name
• SMTP user password
SMTP Configuration 37
Model 2285 Getting Started Guide 3 • Network configuration
• Device mail address
The device mail address specifies the sender’s email address for all log and alarm delivery emails. SMTP servers
often check only the sender’s host domain name of the email address for validity. Consequently, the email
address set for the device can use an arbitrary username with a registered hostname (i.e.
arbitrary_user@yahoo.com or anybody@patton.com).
The SMTP user name and SMTP user password are required when either SMTP with authentication or POPbefore-SMTP mode is selected.
Figure 13. IP filtering configuration
IP Filtering
The Model 2285 prevents unauthorized access using an IP address based filtering method (see figure 13). The
users can allow one of the following scenarios by changing the parameter settings:
• Any host cannot access a specific service of the Model 2285
• Only one host of a specific IP address can access a specific service of the Model 2285
• Hosts on a specific subnet can access a specific service of the Model 2285
• Any host can access a specific service of the Model 2285
The IP filtering feature is intended to control access to Telnet console, SSH console, Web server or each port,
which may be enabled or disabled. The factory default of the filtering feature is “All services and ports are
accessible from any host”.
The meanings of each parameter in IP filtering configuration are as follows:
Interface
Apply IP filtering rule to the incoming packet of Model 2285. This is fixed parameter as eth0(Read-Only).

access the Model 2285. The user must then enter the IP address and subnet of access. Any user on a remote
host must stay in the specified subnet boundary to access the Model 2285. To allow only a specific host to
access the Model 2285, enter the IP address of the specific host and just give 255.255.255.255 for the subnet
with Normal option. To allow any hosts to have access to the Model 2285, give 0.0.0.0 for both of the IP

The Model 2285 also provides users with simple configuration way to block a specific service(s) or serial ports
from all hosts. If the user should set any service option as “Drop all” (see table 14), then all access to the service
from the network will be blocked.

Model 2285 Getting Started Guide 3 • Network configuration
SYSLOG server configuration
The Model 2285 supports the use of a remote message logging service, SYSLOG service for the system and
port data logging. To use the remote SYSLOG service, the user must specify the SYSLOG server’s IP address
and the facility to be used. Figure 15 shows the SYSLOG server configuration page which is located in the
web interface.
Figure 15. SYSLOG server configuration
To receive log messages from the Model 2285, the SYSLOG server must be configured as “remote reception
allowed”. If there is a firewall between the Model 2285 and the SYSLOG server, there must be a rule that
allows all outgoing and incoming UDP packets to travel across the firewall.
The Model 2285 supports SYSLOG facilities from local0 to local7. The user can employ these facilities to save
messages from the Model 2285 separately in the SYSLOG server.
If the SYSLOG service is enabled and the SYSLOG server configuration is properly set up, the user may configure the storage location for the system log or port data log of the Model 2285 as SYSLOG server. For more
information about the configuration of port/system log storage location, refer to section“Port Logging” on
page 68 and section “System Logging” on page 72.
Locating server
Overview
If users want the Model 2285 to work as a server (TCP or UDP), the host acting as a client has to know the IP
address of the Model 2285. However, under the dynamic IP address environment such as DHCP, arbitrary IP
address can be assigned to the Model 2285, which means special consideration is required to access the current
IP address of it. To tackle this problem, the Model 2285 can be configured to send its IP address information
whenever it is assigned a new IP address or periodically to a specific server called locating server. You can operate a specific host as your locating server or you can use your client host as a locating server simultaneously.
No special library or toolkit to implement locating server is provided. You have to implement your own application by using the protocol provided below or contact us.

Note Local ports: Each 2 byte data represent current local port setting of the corre-
sponding serial port. Local ports data length of Model 2285 should be 2
bytes. Configured local TCP (or UDP) port numbers for each serial port are
filled in the serial port number order base, (i.e. TCP or UDP port number
for serial port 1 first). If serial port is disabled, the local port number of that
serial port is regarded as 0.
Example of the Model 2285:
If port number = 7001 (1B59h), Local ports data = 1Bh, 59h
If serial port is disabled, Local port data = 00h, 00h
NFS server configuration
The Model 2285 supports NFS (Network File System) service for system or port data logging functions. To use
this service, the user must specify the IP address of a NFS server and the mounting path on the NFS server.
Figure 17 displays the NFS server configuration page located in the web configuration interface.
Figure 17. NFS server configuration
To store the Model 2285 log data to the NFS server, the NFS server must be configured as “read and write
allowed”. If there is a firewall between the Model 2285 and the NFS server, there must be a rule that allows all
outgoing and incoming packets to travel across the firewall.
If the NFS service is enabled and the NFS server configuration is properly set up, the user may configure the
storage location for the system log or port data log of the If there is a firewall between the Model 2285 and the
SYSLOG server, there must be a rule that allows all outgoing and incoming UDP packets to travel across the
Model 2285 as the NFS server. For more information about the configuration of port/system log storage location, refer to section“Port Logging” on page 68 and section “System Logging” on page 72.
TCP service configuration
If a TCP session is established between two hosts, the connection should be closed (normally or abnormally)
by either of the hosts to prevent the lock-up of the corresponding TCP port. To prevent this type of lock-up
situation, the Model 2285 provides a TCP “keep-alive” feature. The Model 2285 will send packets back and
forth through the network periodically to confirm that the network exists . The corresponding TCP session is
closed automatically if there’s no response from the remote host.
NFS server configuration 42
Model 2285 Getting Started Guide 3 • Network configuration
To use the TCP “keep-alive” feature with the Model 2285, the users should configure three parameters
as follows:
• TCP keep-alive time: This represents the time interval between the last data transmission and keep-alive
packet submissions by the Model 2285. These “keep-alive” messages are sent to the remote host to confirm
that the session is still open. The default time value is 15 sec.
• TCP “keep-alive” probes: This represents how many “keep-alive” probes will be sent to the remote host,
until it decides that the connection is dead. Multiplied with the “TCP ’keep-alive’ intervals”, this gives the
time that a link is forced to close after a “keep-alive” packet has been sent for the first time. The default is
3 times
• TCP keep-alive intervals: This represents the waiting period until a “keep-alive” packet is retransmitted.
The default value is 5 seconds.
By default, the Model 2285 will send the keep-alive packets 3 times with 5 seconds interval after 15 seconds
have elapsed since the time when there’s no data transmitted back and forth.

Model 2285 Getting Started Guide 4 • Serial port configuration
Overview
The serial port configuration capability allows the user to configure the host mode of each port, serial communication parameters, cryptography, port logging parameters and other related parameters.
The serial port’s host mode can be set as any of the following:
• TCP: The Model 2285 operates as a TCP server and client. If the connection is not established, it accepts
all incoming connections from any registered remote hosts and connects to the registered remote hosts if
there is any data from the serial devices. Otherwise, it will send data back and forth. In summary, the Model
2285 will work as if it is virtually connected to the remote host.
• UDP: The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol.
• Modem emulation: Select this mode when the serial device becomes ready to support modem AT com-
mands or users want to perform the session control by using AT commands. Only TCP session
is supported.
With the port-logging feature while in console server mode, the data sent through the serial port is transferred
to MEMORY or NFS server’s storage. The user can also define keywords for each serial port that will trigger an
email or SNMP trap notification. This will enable the user to monitor the data from the attached device.
Using MEMORY to store data will result in loss of all information when the Model 2285 is turned off. Use the
NFS server to preserve the serial port log data.
The serial ports can be configured individually or all at once. Table 5 on page 45 summarizes the configuration
parameters related to the serial port configuration.

Host Mode Configuration
The Model 2285 operating mode is called the “host mode.” Three host modes are available:
• TCP mode: The Model 2285 works as both TCP server and client. This mode works for most applications,
since it will transfer the data either from serial port or from TCP port. If there is no connection established
on a TCP port, the TCP port accepts a connection request from any registered remote hosts and relays the
transmitted data to the coupled serial port. If there is any data from the serial port, it connects to the registered remote hosts and redirects the data.
• UDP mode: The UDP mode operation is similar to that of TCP mode except that it utilizes UDP protocol
• Modem emulation mode: Select this mode when the serial device already supports modem AT commands
or users want to perform the session control by using AT commands. Only TCP session is supported.

Figure 23. Host mode configuration (TCP mode)
TCP mode
For easier understanding of TCP modes, a simplified State Transition Diagram is often used. And to help users
understand the diagram, the TCP state of the Model 2285 is briefly described as follows.
• [Listen]—It represents “a waiting for a connection request from any registered remote host”. It is a default
start-up mode when it is set as TCP mode.
• [Closed]—It means “no connection state”. If the data transfer between a remote host and the Model 2285
is completed, the state is changed to this state as a result that either of the remote host or the Model 2285
sent a disconnection request. After this, the state is automatically changed to [Listen] mode.
• [Sync-Received]—The state is changed from [Listen] to [Sync-Received] if one of the remote hosts has sent
a connection request. If the Model 2285 accepts the request, the state is changed into [Established].
• [Sync-Sent]—If the Model 2285 has sent a connection request to a remote host, the state is changed from
[Closed] to [Sync-Sent]. This state is maintained until the remote host accepts the connection request.
• [Established]—It represents “an open connection”. If one of the hosts, the remote host or the Model 2285,
accepts a connection request from the other, the connection is opened and state is changed into [Established].
• [Data]—When it is in [Established] state, data from a host will be transferred to the other one. For easier
understanding of the TCP session operation, we called the state as [Data] state when actual data transfer is
performed. Actually, the [Data] mode is a part of [Established] state as is described in the RFC 793 [Transmission Control Protocol]. This is a normal state for the data transfer phase of the connection.
Serial Port Configuration 49
Model 2285 Getting Started Guide 4 • Serial port configuration
The Model 2285 works as either TCP server or client according to the situation. This will be the typical mode
for most applications, since it will transfer the data either from serial port or from TCP port. The default TCP
state is [Listen] which is the same as that of TCP server mode.
1) Typical State Transition
[Listen] --> [Sync-Received] --> [Established] --> [Data] --> [Closed] --> [Listen]
Or
[Listen] --> [Sync-Sent] --> [Established] --> [Data] --> [Closed] --> [Listen]
The initial state is [Listen]. If there are data coming from the serial port, it will connect to the remote host as a
TCP client and then transfer data through the TCP port. If there is incoming connection request from the
remote host, it will accept the connection as a TCP server, and then transfer data through the serial port. Thus,
users can assume that the Model 2285 is always connected to the specified remote host.
2) Operations
Serial data transfer
Whenever the serial device sends data through the serial port of the Model 2285, data will be accumulated
on the serial port buffer of the Model 2285. If the buffer is full or the time gap reaches the inter-character
timeout (see section “Serial port parameters” on page 63 for details on inter-character timeout), the Model
2285 connects to the registered remote host(s), if a TCP session has not been established yet. If the Model
2285 succeeds in connecting to the remote host, the data in the serial port buffer will be transferred to the
host. Otherwise, all the data stored in the buffer will be cleared.
Session disconnection
The connected session will be disconnected when the remote host sends disconnection request or when no
data transfer activity is found through the serial port for certain amount of time, which is “Inactivity time-
out” (See section “Serial port parameters” on page 63 for details on Inactivity timeout). All the data
remained in the serial port buffer will be cleared when it is disconnected.
Connection request from remote host
All the incoming TCP connection requests will be rejected in TCP client mode.
3) Parameters
TCP listening port
This is the TCP port number through which a remote host can connect a TCP session, and, send and
receive data. Incoming connection request(s) to the ports other than TCP Listening Port will be rejected.
The Model 2285 does restrict the port number from 1024 to 65535 and if it is set as 0 only outgoing connection is permitted. (TCP server mode)
User authentication
If the User authentication option is enabled, the user can access the port after entering the correct user ID
and password. Refer to section “User administration” on page 79 for details of user management.
Telnet protocol
In TCP mode, Model 2285 supports Telnet Com Port Control Option (RFC2217 compliant) so that user
can control serial parameters like baud rate, data bits and flow control option using his local RFC2217-
Serial Port Configuration 50
Model 2285 Getting Started Guide 4 • Serial port configuration
compliant Telnet client program. (Refer to section “Serial port parameters” on page 63 for more detail
information about serial parameters)
Usually this option is used with the RFC2217-compliant COM port redirector so that user can control
parameters of serial ports of Model 2285 using his serial port application program.
For this purpose, Patton OEM version of Serial/IP from Tactical Software, LLC is bundled with Model
2285. Refer to documentations of Serial/IP for more detail information about using the COM port redirector. (Refer to appendix G, “Using Model 2285 with Serial/IP” on page 116 for more
detail information)
Max. allowed connection
The Model 2285 supports up to 8 multiple connections from external host(s) to the serial port. If there are
remote host connections by the remote host list configuration already, possible number of connection will
be reduced (Max. allowed connection - remote host(s) connected already). For example, if user set Max.
allowed connection as 8 and if there are 3 connections from Model 2285 to remote hosts, which are configured in the remote host list, then maximum number of connection from external hosts to a serial port
will be reduced to 5. For more detailed information on remote host list configuration, refer to section
“Remote host configuration” on page 58.
Cyclic Connection
If Cyclic Connection function is enabled, the Model 2285 will make an attempt to connect to the userdefined remote host(s) at a given interval even if there’s no incoming serial data from the device connected
to that serial port. If there is data on the remote host(s) to be sent to serial device, it can be transferred to
the serial device via Model 2285 serial port after the connection is established. Eventually, users can monitor the serial device periodically by making the remote host send the serial command to the Model 2285
whenever it is connected to the remote host. This option is useful when users need to gather the device
Serial Port Configuration 51
Model 2285 Getting Started Guide 4 • Serial port configuration
information periodically even if the serial device does not send its data periodically. Figure 24 shows the
State Transition Diagram of the session operations in TCP mode.
Figure 24. State Transition Diagram of TCP mode
Inactivity Timeout
When Inactivity Timeout function is enabled, connection between remote host(s) and Model 2285 will be
closed automatically if there is no data transmission during the value which is set in Inactivity
Timeout configuration.
Serial Port Configuration 52
Model 2285 Getting Started Guide 4 • Serial port configuration
UDP mode
The UDP mode operation is similar to that of TCP mode except that it is based on UDP protocol and only
one pre-defined remote host is able to communicate with the Model 2285. Users do not have to configure
cyclic connection, since UDP is a connectionless protocol.
Figure 25. Host mode configuration (UDP mode)
1) Operations
If a remote host sends a UDP datagram to the one of UDP Local port of the Model 2285, Model 2285 first
checks whether it is from one of the hosts configured on remote host configuration. If the remote host is one of
the hosts configured on remote host configuration, then Model 2285 transfers the data through the serial port.
Otherwise, the Model 2285 discards the incoming UDP datagram. But user can force Model 2285 accept all
incoming UDP datagram regardless remote host configuration by setting Accept UDP datagram from unlisted
remote host parameter as Yes. If there is any incoming data from the serial port, the Model 2285 transfers the
data to the remote host defined on remote host configuration. If the remote port is not opened, the Model 2285
will not transfer the data.
2) Parameters
UDP receiving port
The concept is the same as TCP listening port.
Max. allowed connection
The concept is the same as that of TCP communication.
Accept UDP datagram from unlisted remote host
If Accept unlisted (Accept UDP datagram from unlisted remote host) function is set as No, Model 2285 will
accept only incoming UDP datagram from the remote host(s) configured on remote host configuration. On
Serial Port Configuration 53
Model 2285 Getting Started Guide 4 • Serial port configuration
the contrary, if Accept unlisted function is set as Yes , Model 2285 will accept all incoming UDP datagram
regardless remote host configuration.
Send to recent unlisted remote host
If Send unlisted (Send to recent unlisted remote host) function is set as Yes , Model 2285 sends data to the
remote host, which has connected Model 2285 recently. Recent unlisted remote host is a remote host,
which has accessed a corresponding serial port of Model 2285 but is not configured on remote host configu-
ration. Surely, Model 2285 also send data to the hosts, which are configured on remote host configuration. If
Send unlisted function is set as No, Model 2285 sends data only to the host(s) which are configured on
remote host configuration. Model 2285 maintains a recent unlisted remote host during the
Inactivity Timeout.
Inactivity Timeout
In UDP mode, Inactivity Timeout is used in maintaining recent unlisted remote host. If there is no data
transmission between unlisted remote host and serial port of Model 2285 during Inactivity Timeout,
Model 2285 will not send data from a serial port to the recent unlisted remote host again. Namely, Inactiv-
ity Timeout in UDP mode is the time maintained recent unlisted remote host list by Model 2285.
Note If user set Inactivity Timeout as 0 in UDP mode, Model 2285 does not allow
any new connection from/to remote host if the number of current remote
host exceeds Max. allowed connection.
Modem emulation mode
1) Operations
In modem emulation mode, the serial port process acts as if it is a modem attached to the serial device. It
accepts AT modem commands and answers to them, as modems would do. It also handles the modem signals
correctly. Modem emulation mode is useful in the following cases.
• There already exists a modem attached to the user’s serial device.
If user’s serial device already has a modem for phone-line connection, it can be just replaced by the Model
2285 for Ethernet connection. What users need to do is to use an IP address (or domain name) and port
number instead of phone number as a parameter of ATA/ATDT commands.
• It is required to send serial data to the multiple remote hosts.
If the serial device should send data to the multiple hosts, modem emulation mode is required. For example, the first data from the serial device can be sent to the first data acquisition server and the second to the
second server. What user device has to do is to change the IP address (or domain name) and port number
parameters whenever the device sends ATD(T) XXX command.
Serial Port Configuration 54
Model 2285 Getting Started Guide 4 • Serial port configuration
By using the modem emulation mode of the Model 2285, users can have their serial device connected to the
Ethernet network easily, which is cheaper than using phone line modem. Table 6 is a summarized AT command table which is supported by the Model 2285. Figure 26 on page 57 shows the typical case of the serial
port command flow when ATDA command is used to connect to the Ethernet network.

Remote host configuration
Remote host configuration is the list of hosts that will receive data from serial port of Model 2285 when there
is data transmission from the serial port of the Model 2285.
In TCP mode, user can also configure secondary remote host (Backup host) that will receive data from serial
port if Model 2285 fails to connect to primary remote host. If a connection to the primary remote host can be
Serial Port Configuration 58
Model 2285 Getting Started Guide 4 • Serial port configuration
made, Model 2285 dose not send data to secondary remote host until connection to primary remote host
failed. And the maximum possible number of primary remote host is limited up to 4 remote connections.
In UDP mode, user can only configure a primary remote host because there is no way for Model 2285 to check
status of primary remote host, so secondary remote host is meaningless.
The maximum number of remote host is limited up to 4 in the Model 2285. Figure 28 shows Remote host
configuration pages of the Web UI. (TCP mode)
User can also set any effective domain name as Host IP address in the Remote host configuration.

Serial Port Configuration 59
Model 2285 Getting Started Guide 4 • Serial port configuration
Cryptography configuration
The Model 2285 supports encrypted sessions for only the TCP mode including modem emulation mode (not
UDP mode).
Figure 29. Cryptography configuration
Secure Sockets Layer(SSL) cryptography method
By setting the cryptography method as SSL, the Model 2285 can communicate with another device supporting
SSLv3 cryptography method during encrypted sessions.
SSL was developed by Netscape for use between clients and servers. SSL layers on top of any transport protocol
and can run under application protocols such as HTTP. SSL aims to be secure, fast, and adaptable to other
Web protocols. SSL provides data security for applications that communicate across networks. SSL is a transport-layer security protocol layered between application protocols and TCP/IP.
To initiate SSL sessions, exchange of messages called the SSL handshake is required between two devices
(Server and Client). The SSL protocol uses a combination of public-key and symmetric key encryption. Symmetric key encryption is much faster than public-key encryption, but public-key encryption provides better
authentication techniques. The handshake allows the server to authenticate itself to the client using public-key
techniques, and then allows the client and the server to cooperate in the creation of symmetric keys used for
rapid encryption, decryption, and tamper detection during the session that follows. The details of handshake
process step involved can be summarized as follows:
1. The client sends the server the client’s SSL version number, cipher settings, randomly generated data, and
other information the server needs to communicate with the client using SSL.
Serial Port Configuration 60
Model 2285 Getting Started Guide 4 • Serial port configuration
2. The server sends the client the server’s SSL version number, cipher settings, randomly generated data, and
other information the client needs to communicate with the server over SSL. The server also sends its own
certificate and, if the client is requesting a server resource that requires client authentication, requests the
client’s certificate.
3. The client uses some of the information sent by the server to authenticate the server. If the server cannot be
authenticated, the user is warned of the problem and informed that an encrypted and authenticated connection cannot be established. If the server can be successfully authenticated, the client goes on to
next step.
4. Using all data generated in the handshake so far, the client (with the cooperation of the server, depending
on the cipher being used) creates the premaster secret for the session, encrypts it with the server’s publickey (obtained from the server’s certificate, sent in step 2), and sends the encrypted premaster secret to the
server. SSL differ in the way this "shared" master secret is created
5. If the server has requested client authentication (an optional step in the handshake), the client also signs
another piece of data that is unique to this handshake and known by both the client and server. In this case
the client sends both the signed data and the client’s own certificate to the server along with the encrypted
premaster secret.
6. If the server has requested client authentication, the server attempts to authenticate the client. If the client
cannot be authenticated, the session is terminated. if the client can be successfully authenticated, the server
uses its private key to decrypt the premaster secret, then performs a series of steps (which the client also
performs, starting from the same premaster secret) to generate the master secret.
7. Both the client and the server use the master secret to generate the session keys, which are symmetric keys
used to encrypt and decrypt information exchanged during the SSL/TLS session and to verify its integrity—that is, to detect any changes in the data between the time it was sent and the time it is received over
the SSL connection.
8. The client sends a message to the server informing it that future messages from the client will be encrypted
with the session key. It then sends a separate (encrypted) message indicating that the client portion of the
handshake is finished.
9. The server sends a message to the client informing it that future messages from the server will be encrypted
h the session key. It then sends a separate (encrypted) message indicating that the server portion of the
handshake is finished.
10. The SSL handshake is now complete, and the SSL session has begun. The client and the server use the ses-
sion keys to encrypt and decrypt the data they send to each other and to validate its integrity.

Figure 30. Typical SSL Handshake Process
The Model 2285 can act as a SSL server or as a SSL client depending on status of TCP mode. If TCP connection with SSL is initiated from remote host first, Model 2285 acts as a SSL server during the SSL handshake
process. On the contrary, if TCP connection with SSL is initiated from serial port of Model 2285 first, Model
2285 acts as a SSL client during the SSL handshake process.

Serial port parameters
To connect the serial device to the Model 2285 serial port, the serial port parameters of the Model 2285 should
match exactly to that of the serial device attached. The serial port parameters are required to match this serial
communication. The parameters required for the serial communication are: UART type, baud rate, data bits,
parity, stop bits, flow control DTR/DSR behavior and inter-character timeout.
• UART type: First of all, the Model 2285 and the serial device must agree on the serial communication type,
which is one of RS232 mode, RS422(RS485 full) mode or RS485 half mode. User can set the serial com-

Note Turn off the power of the Model 2285 device before changing the position
of DIP switch in case of Model 2285. Changing the position of DIP switch
while the power is on may cause damage to the device.
(If the DIP switches are set incorrectly the Model 2285 will display
“Invalid” for the UART type on the UI as shown on Figure 33, which will
hinder communications to the serial port.)
\
Figure 33. Invalid UART type settings displayed on the Serial port configuration main screen
• Baud rate: The valid baud rate for the Model 2285 is as follows: 75, 150, 200, 300, 600, 1200, 2400, 4800,
9600, 14400, 19200, 38400, 57600, 115200, and 230400. The factory default setting is 9600.
• Data bits: Data bits can be between 7 bits and 8 bits. The factory default setting is 8 bits.
• Parity: Parity can be none, even or odd. The factory default setting is none.
• Stop bits: Stop bits can be between 1 bit and 2 bits. The factory default setting is 1 bit.

Model 2285 Getting Started Guide 4 • Serial port configuration
Figure 34. Serial parameter configuration
• Flow control: The factory default setting of the flow control is None. Software Flow Control using XON/
XOFF and hardware flow control using RTS/CTS are supported by the Model 2285.
Software flow control method controls data communication flow by sending special characters XON/XOFF
(0x11/0x13) between two connected devices. And hardware flow control method controls data communication flow by sending signals back and forth between two connected devices.
Note Flow control is supported only in RS232 and RS422 mode. RS485 mode
does not support any kind of flow control method.
• DTR/DSR behavior: Purpose of the DTR/DSR pin is to emulate modem signal control or to control TCP
connection state by using serial port signal. The DTR is a write-only output signal, whereas the DSR is a
read-only input signal in the Model 2285.
The DTR option can be set to one of three types: always high, always low or high when TCP/UDP is opened.
If the DTR behavior is set to high when TCP/UDP is opened, the state of the DTR pin will be maintained
high if the TCP/UDP connection is established.
The DSR input behavior can be set to one of two types: none or allow TCP/UDP connection only by high. If
user sets the DSR input behavior as Allow TCP/UDP connection only by HIGH, TCP connection to remote
host from Model 2285 is made only when the DSR status is changed from low to high. And TCP connection to remote host is disconnected when the DSR status is changed from high to low. And also Model
2285 accepts TCP connection from the remote host only when the DSR status is high. In case of UDP
mode, Model 2285 receives UDP data from the remote host only when the DSR status is high. But In
modem emulation mode, the connection to the remote host will be disconnected when the DSR status is
changed from high to low regardless of the value of DSR behavior.
Serial Port Configuration 65
Model 2285 Getting Started Guide 4 • Serial port configuration
Serial device connected to Model 2285 can control TCP/UDP connection of Model 2285 by controlling
DTR signal of it.
Note DTR/DSR behavior configuration will not be effective when the modem is
enabled. DTR/DSR behavior does not effective in RS422 and RS485 mode.
• Inter-character timeout: This parameter defines the interval the Model 2285 fetches the overall serial data
from its internal buffer. If there is an incoming data through the serial port, the Model 2285 stores data into
the internal buffer. The Model 2285 transfers data stored in the buffer via TCP/IP, only if the internal
buffer is full or if the inter-character time interval reaches the time specified in the inter-character timeout
setting. If inter-character timeout is set at 0, then data stored in the internal buffer will be transferred immediately without any delay.
Optimal inter-character timeout would be different according to your application but at least it must be
larger than one character interval within specified baud rate. For example, assume that the serial port is set
to 1200 bps, 8 Data bits, 1 stop bit, and no parity. In this case, the total number of bits to send a character
is 10 bits and the time required to transfer one character is
10 (bits) / 1200 (bits/s) * 1000 (ms/s) = 8.3 ms.
Therefore, you have to set inter-character timeout to be larger than 8.3 ms. The inter-character timeout is
specified in milliseconds.
Serial Port Configuration 66
Model 2285 Getting Started Guide 4 • Serial port configuration
Figure 35. Modem configuration
Modem configuration
The Model 2285 supports direct modem connection to the serial port. When user wants to connect to a
modem on its serial port, he must configure Modem init-string and DCD behavior on the modem configuration page. The Model 2285 supports modem connection only when host mode is set as TCP mode.
• Enable/Disable modem: By enabling this menu, user can attach a modem directly to the serial port of
Model 2285. If this parameter is enabled, Model 2285 considers this port will be used for modem
use exclusively.
• Modem init-string: User can specify modem initialization string for his modem in Modem init-string
parameter. When a serial port is set to modem mode by setting Enable/Disable modem parameter as Enabled,
Model 2285 sends modem initialization string to the serial port whenever rising edge of DTR pin is
detected or parameter related with serial port configuration is changed.
• DCD behavior: If DCD behavior is set as Allow TCP connection only by HIGH, Model 2285 permits a con-
nection from the remote host only when the DCD status of serial port is high. This feature is useful when
user want to use a serial port only for dial-in modem mode. In this case, if there is no connection through
modem already, Model 2285 will not permit a TCP side connection.
• Automatic release modem connection: If Automatic release modem connection is set as Enable, modem con-
nection will be closed by Model 2285 if all TCP connections are closed. If this option is set as Disable,
modem connection will not be closed by Model 2285 even if all TCP connections are closed. Please note
that actual phone line connection will be closed if one of modems closes connection. That is, this option
Serial Port Configuration 67
Model 2285 Getting Started Guide 4 • Serial port configuration
can be used for Model 2285 to allow disconnection of a modem connection by itself when all TCP connections are closed.
If user wants to use dial-out function, he should set DCD behavior as None because he must be able to
access modem connected to a serial port to send dial out command to the modem first.
Port Logging
With the port logging feature, the data sent through the serial port is stored to MEMORY or a mounting point
on an NFS server.
• Enable/disable port logging: This parameter defines whether to enable or disable the port-logging feature.
The factory default setting is [disabled].
• Port log storage location: The port log data can be stored to the Model 2285’ internal memory or the
mounting point on an NFS server. If the internal memory is used to store port log data, the port log data
will be cleared when the Model 2285 is turned off. To preserve the serial port log data, set the storage location to be the NFS server. To do this, the user must configure the NFS server in advance. Refer to section
“NFS server configuration” on page 42 for details of NFS server configuration.
• Port log buffer size: This parameter defines the maximum amount of port log data to be logged. When
using internal memory to store the log data, the total size of the port buffer cannot exceed 10 kbytes.
When using an NFS server to store log data, the maximum port buffer size is unlimited. The user should
configure the NFS server to ensure that the port logging system works properly.

Figure 37. Port event-handling configurations
Port event handling configurations
The Model 2285 provides users with a means for monitoring or reacting to data from serial device attached to
a serial port of it through Port event handling configuration. Namely, user can define keywords for each serial
port that will trigger the email/SNMP notification or command sent to the serial port directly on Port event
handling configuration. This will enable the user to monitor the data from the attached device or to manage/
control a device attached serial port directly when pre-defined keywords are detected. Also, the status of the
connection between the Model 2285 and the serial device and the status of the TCP connection between the
Model 2285 and remote hosts could be monitored and managed as well.
Each reaction can be configured individually upon each event. Reaction can be an email delivery, SNMP trap
sending, command sending or a combination of the reactions.
• Port event handling: If the user wants to enable port event handling feature, set Port event handling as
enable. This is a global parameter so if this feature is disabled, the Model 2285 does not take any actions on
port events.
• Notification interval: To prevent Model 2285 from being trapped in handling port event, there is a Notifi-
cation interval parameter. Model 2285 will send notification email or SNMP trap every Notification interval
even it detects predefined keyword within Notification interval. The smaller value of this parameter will
result in immediate response for predefined keyword and heavy usage of system resources. The largest value
accepted by user is recommended to prevent system resource usage minimization.
Serial Port Configuration 69
Model 2285 Getting Started Guide 4 • Serial port configuration
Note The port command in keyword response is not affected by this parameter.
Port command will be sent immediately when the corresponding keyword
is detected.
• Email notification: This parameter enables or disables Email notification feature of the Model 2285. When
Model 2285 sends Email notification, it uses the SMTP server configured in SMTP server configuration. If
the SMTP server is not configured correctly or disabled, Email feature will be disabled. For details of SMTP
server configurations and descriptions, refer to section “SMTP Configuration” on page 37.
• Subject of Email: This parameter set the subject of Email that will be sent by Model 2285 when pre-defined
keyword is detected.
• Recipient’s Email address: This parameter set mail recipient who will receive notification mail when pre-
defined keyword is detected.
• SNMP trap notification: This parameter enables or disables SNMP trap notification feature of
Model 2285.
• Subject of SNMP trap: This parameter set the subject of SNMP trap that will be sent by Model 2285 when
pre-defined keyword is detected.
• SNMP trap receiver’s IP address: This parameter sets the IP address of SNMP trap receiver that will receive
SNMP trap notification when pre-defined keyword is detected.
• SNMP trap community: This parameter sets a community that will be included in SNMP trap message
when pre-defined keyword is detected.
• SNMP trap version: This parameter sets a version of SNMP trap, which will be sent when pre-defined key-
word is detected.
Event keywords
The user can assign event keywords so that the Model 2285 takes actions such as sending e-mail notification,
sending SNMP trap notification or sending pre-defined command to a serial port if the keyword is detected at
the serial port.
• Event keyword: User can specify any words, which he/she wants to set as a keyword.
• Email notification: User can select enable or disable for the Email notification action on keyword selected.
• SNMP trap notification: User can select enable or disable for the SNMP trap notification action on key-
word selected.
• Port command: Model 2285 supports direct reaction to a device attached to serial port when pre-defined
keyword is detected. User can specify command or string, which will be sent to a serial port on this menu.

Introduction
The Model 2285 displays the system status and the log data via a Status Display Screen. This screen is used for
management purposes. System status data includes the model name, serial number, firmware version and the
network configuration of the Model 2285. The Model 2285 can also be configured to deliver log data automatically via email to a specified recipient with the system-logging feature.
The users can configure the Model 2285’ device name, date and time settings, and reload factory default settings in this menu group. The users can also upgrade the firmware of the Model 2285 using the web interface,
remote consoles or serial console.
Figure 38. System status display
System Logging
The Model 2285 provides both the system logging feature and the system log status display. The user may configure the Model 2285 to enable or disable the system logging process, the system log buffer size, as well as
select the log storage location.
System log storage location: The system log can be stored in the Model 2285 internal memory, the mounting
point on an NFS server or the SYSLOG server. If the internal memory is used to store system log data, the log
data will be cleared when the Model 2285 is turned off. To preserve the system log data, set the storage location
to be SYSLOG server or NFS server. To do this, the user must configure the corresponding media in advance.
Unless the media is properly set up, the log will not be written to a specified storage location properly.
Introduction 72
Model 2285 Getting Started Guide 5 • System administration
Figure 39. System log configuration and view
The Model 2285 can also be configured to send log data automatically if the number of logs unsent reaches a
pre-defined number. If enabled, the user must set parameters to initiate the creation of a email. These parameters would include the number of logs required to trigger an email, the recipient’s email address, etc. Figure 39
shows the configuration and system log view screen.
Change Password
The password for the administrative system user (root) of Model 2285 can be changed using this menu.
This password is required when user wants to access serial console, telnet/ssh console or Web UI of Model
2285. (Refer to the section “User administration” on page 79 for details about port user management)

Model 2285 Getting Started Guide 5 • System administration
Device Name Configuration
The Model 2285 has its own name for administrative purposes. Figure 41 shows the device name configura-
tion screen. When user changes Device name, hostname of Model 2285 will be also changed.
Figure 41. Device name configuration
Note The user cannot set space character as a device name. If user sets blank as
Device name then hostname is set as IP address of Model
2285 automatically.
And also the device name is utilized for management program, Model 2285
Manager.
Date and Time Settings
The Model 2285 maintains current date and time information.
Note The Model 2285 does not have a battery for internal clock. Current date and
time setting will not be retained after system rebooting. So it is recommended to use NTP server to maintain correct date and time in the
Model 2285.
The user can change the current date and time, as shown in figure 42.
Figure 42. Date and time configuration
Device Name Configuration 74
Model 2285 Getting Started Guide 5 • System administration
The user can also use an NTP (Network Time Protocol) server for setting the time of the Model 2285 as
shown in figure 43. If the NTP feature is enabled, the Model 2285 will obtain the date and time information
from the NTP server at each reboot. If the NTP server is set to 0.0.0.0, the Model 2285 will use the default
NTP servers. In this case, the Model 2285 should be connected from the network to the Internet. The user
may also need to set the time offset from UTC depending on the users’ location.

Introduction 81
Model 2285 Getting Started Guide 6 • System statistics
IP Statistics
The IP Statistics screen provides statistical information about packets/connections using an IP protocol. Definitions and descriptions of each parameter are described below:
Figure 51. IP statistics
• Forwarding: Specifies whether IP forwarding is enabled or disabled.
• DefaultTTL: Specifies the default initial time to live (TTL) for datagrams originating on a
particular computer.
• InReceives: Shows the number of datagrams received.
• InHdrErrors: Shows the number of datagrams received that have header errors. Datagrams Received
Header Errors is the number of input datagrams discarded due to errors in their IP headers, including bad
checksums, version number mismatch, other format errors, time-to-live exceeded, errors discovered in processing their IP options, etc.
• InAddrErrors: Specifies the number of datagrams received that have address errors. These datagrams are dis-
carded because the IP address in their IP header’s destination field was not a valid address to be received at
this entity. This count includes invalid addresses (for example, 0.0.0.0) and addresses of unsupported
Classes (for example, Class E).
• ForwDatagrams: Specifies the number of datagrams forwarded.
• InUnknownProtos: Specifies the number of locally addressed datagrams received successfully but discarded
because of an unknown or unsupported protocol.
• InDiscard: Specifies the number of input IP datagrams for which no problems were encountered to prevent
their continued processing, but which were discarded (for example, for lack of buffer space). This counter
does not include any datagrams discarded while awaiting reassembly.
Serial Ports Statistics 82
Model 2285 Getting Started Guide 6 • System statistics
• InDelivers: Specifies the number of received datagrams delivered.
• OutRequests: Specifies the number of outgoing datagrams that an IP is requested to transmit. This number
does not include forwarded datagrams.
• OutDiscards: Specifies the number of transmitted datagrams discarded. These are datagrams for which no
problems were encountered to prevent their transmission to their destination, but which were discarded (for
example, for lack of buffer space.) This counter would include datagrams counted in Datagrams Forwarded
if any such packets met this (discretionary) discard criterion.
• OutNoRoutes: Specifies the number of datagrams for which no route could be found to transmit them to
the destination IP address. These datagrams were discarded. This counter includes any packets counted in
Datagrams Forwarded that meet this “no route” criterion.
• ReasmTimeout: Specifies the amount of time allowed for all pieces of a fragmented datagram to arrive. If all
pieces do not arrive within this time, the datagram is discarded.
• ReasmReqds: Specifies the number of datagrams that require reassembly.
• ReasmOKs: Specifies the number of datagrams that were successfully reassembled.
• ReasmFails: Specifies the number of datagrams that cannot be reassembled.
• FragOKs: Specifies the number of datagrams that were fragmented successfully.
• FragFails: Specifies the number of datagrams that need to be fragmented but couldn’t be because the IP
header specifies no fragmentation. For example, if the datagrams “Don’t Fragment” flag was set, the datagram would not be fragmented. These datagrams are discarded.
• FragCreates: Specifies the number of fragments created.
Serial Ports Statistics 83
Model 2285 Getting Started Guide 6 • System statistics
ICMP Statistics
The ICMP Statistics screen provides statistical information about packets/connections using an ICMP protocol. Definitions and descriptions of each parameter are described below:
Figure 52. ICMP Statistics
• InMsgs, OutMsgs: Specifies the number of messages received or sent.
• InErrors, OutErrors: Specifies the number of errors received or sent.
• InDestUnreachs, OutDestUnreachs: Specifies the number of destination-unreachable messages received or
sent. A destination-unreachable message is sent to the originating computer when a datagram fails to reach
its intended destination.
• InTimeExcds, OutTimeExcds: Specifies the number of time-to-live (TTL) exceeded messages received or
sent. A time-to-live exceeded message is sent to the originating computer when a datagram is discarded
because the number of routers it has passed through exceeds its time-to-live value.
• InParmProbs, OutParmProbs: Specifies the number of parameter-problem messages received or sent. A
parameter-problem message is sent to the originating computer when a router or host detects an error in a
datagram’s IP header.
• InSrcQuenchs, OutSrcQuenchs: Specifies the number of source quench messages received or sent. A source
quench request is sent to a computer to request that it reduces its rate of packet transmission.
• InRedirects, OutRedirects: Specifies the number of redirect messages received or sent. A redirect message is
sent to the originating computer when a better route is discovered for a datagram sent by that computer.
• InEchos, OutEchos: Specifies the number of echo requests received or sent. An echo request causes the
receiving computer to send an echo reply message back to the originating computer.
ICMP Statistics 84
Model 2285 Getting Started Guide 6 • System statistics
• NEchoReps, OutEchoReps: Specifies the number of echo replies received or sent. A computer sends an
echo reply in response to receiving an echo request message.
• InTimestamps, OutTimestamps: Specifies the number of time-stamp requests received or sent. A time-
stamp request causes the receiving computer to send a time-stamp reply back to the originating computer.
• InTimestampReps, OutTimestampReps: Specifies the number of time-stamp replies received or sent. A
computer sends a time-stamp reply in response to receiving a time-stamp request. Routers can use timestamp requests and replies to measure the transmission speed of datagrams on a network.
• InAddrMasks, OutAddrMasks: Specifies the number of address mask requests received or sent. A computer
sends an address mask request to determine the number of bits in the subnet mask for its local subnet.
• InAddrMaskReps, OutAddrMaskReps: Specifies the number of address mask responses received or sent. A
computer sends an address mask response in response to an address mask request.
TCP Statistics
The TCP Statistics screen provides statistical information about packets/connections using a TCP protocol.
Definitions and descriptions of each parameter are described below:
Figure 53. TCP Statistics
• RtoAlgorithm: Specifies the retransmission time-out (RTO) algorithm in use. The Retransmission Algo-
rithm can have one of the following values.
- 0: CONSTANT - Constant Time-out
- 1: RSRE - MIL-STD-1778 Appendix B
- 2: VANJ - Van Jacobson’s Algorithm
- 3: OTHER - Other
• RtoMin: Specifies the minimum retransmission time-out value in milliseconds.
• RtoMax: Specifies the maximum retransmission time-out value in milliseconds.
• MaxConn: Specifies the maximum number of connections. If is the maximum number is set to -1, the
maximum number of connections are dynamic.
TCP Statistics 85
