Chapter 1 Switch Management
1.1 Management Options
After purchasing the switch, the user needs to configure the switch for network
management. ES4700 series provides two management options: in-band management
and out-of-band management.
1.1.1 Out-of-band Management
Out-of-band management is the management through Console interface. Generally,
the user will use out-of-band management for the initial switch configuration, or when
in-band management is not available. For instance, the user must assign an IP address
to the switch via the Console interface to be able to access the switch through Telnet.
The procedures for managing the switch via Console interface are listed below:
Step 1: setting up the environment:
Fig 1-1 Out-of-band Management Configuration Environment
As shown in Fig 1-1, the serial port (RS-232) is connected to the switch with the
serial cable provided. The table below lists all the devices used in the connection.
Device Name Description
PC machine Has functional keyboard and RS-232, with terminal
emulator installed, such as HyperTerminal included in
Windows 9x/NT/2000/XP.
Serial port cable One end attach to the RS-232 serial port, the other end to
the Console port.
Connect with serial port
Page 19
19
ES4700 series Functional Console port required.
Step 2 Entering the HyperTerminal
Open the HyperTerminal included in Windows after the connection established. The
example below is based on the HyperTerminal included in Windows XP.
1) Click Start menu - All Programs -Accessories -Communication - HyperTerminal.
Fig 1-2 Opening HyperTerminal
2) Type a name for opening HyperTerminal, such as “Switch”.
Fig 1-3 Opening HyperTerminal
3) In the “Connecting with” drop-list, select the RS-232 serial port used by the PC, e.g.
COM1, and click “OK”.
Page 20
20
Fig 1-4 Opening HyperTerminal
4) COM1 property appears, select “9600” for “Baud rate”, “8” for “Data bits”, “none” for
“Parity checksum”, “1” for stop bit and “none” for traffic control; or, you can also click
“Revert to default” and click “OK”.
Fig 1-5 Opening HyperTerminal
Step 3 Entering switch CLI interface:
Power on the switch. The following appears in the HyperTerminal windows, that is
the CLI configuration mode for ES4700 series.

ES4700 series Switch
26 Ethernet/IEEE 802.3 interface(s)
Press ENTER to start session
The user can now enter commands to manage the switch. For a detailed description
for the commands, please refer to the following chapters.
1.1.2 In-band Management
In-band management refers to the management by login to the switch using
Telnet. In-band management enables management of the switch for some devices
attached to the switch. In the case when in-band management fails due to switch
configuration changes, out-of-band management can be used for configuring and
managing the switch.
1.1.3 Management via Telnet
To manage the switch with Telnet, the following conditions should be met:
1) Switch has an IP address configured
2) The host IP address (Telnet client) and the switch’s VLAN interface IP address is
in the same network segment.
3) If not 2), Telnet client can connect to an IP address of the switch via other
devices, such as a router.
ES4700 seriesis a Layer 3 switch that can be configured with several IP addresses.
The following example assumes the shipment status of the switch where only VLAN1
exists in the system.
Page 22
22
The following describes the steps for a Telnet client to connect to the switch’s VLAN1
interface by Telnet.
Fig 1-6 Manage the switch by Telnet
Step 1: Configure the IP addresses for the switch
First is the configuration of host IP address. This should be within the same network
segment as the switch VLAN1 interface IP address. Suppose the switch VLAN interface
IP address 10.1.128.251/24. Then, a possible host IP address is 10.1.128.252/24. Run
“ping 10.1.128.251” from the host and verify the result, check for reasons if ping failed.
The IP address configuration commands for VLAN1 interface are listed below.
Before in-band management, the switch must be configured with an IP address by
out-of-band management (i.e. Console mode), The configuration commands are as
follows (All switch configuration prompts are assumed to be “switch” hereafter if not
otherwise specified):
Switch>
Switch>en
Switch#config
Switch(Config)#interface vlan 1
Switch(Config-If-Vlan1)#ip address 10.1.128.251 255.255.255.0
Switch(Config-If-Vlan1)#no shutdown
Step 2: Run Telnet Client program.
Run Telnet client program included in Windows with the specified Telnet target.
Page 23
23
Fig 1-7 Run telnet client program included in Windows
Step 3: Login to the switch
Login to the Telnet configuration interface. Valid login name and password are
required, otherwise the switch will reject Telnet access. This is a method to protect the
switch from unauthorized access. As a result, when Telnet is enabled for configuring and
managing the switch, username and password for authorized Telnet users must be
configured with the following command:
username <user> password {0|7} <password>.
Assume an authorized user in the switch has a username of “test”, and password of
“test”, the configuration procedure should like the following:
Switch
>en
Switch#config
Switch(Config)#username test password 0 test
Enter valid login name and password in the Telnet configuration interface, Telnet
user will be able to enter the switch’s CLI configuration interface. The commands used in
the Telnet CLI interface after login is the same as in that in the Console interface.
Page 24
24
Fig 1-8 Telnet Configuration Interface
1.1.4 Management via HTTP
To manage the switch via HTTP, the following conditions should be met:
1) Switch has an IP address configured
2) The host IP address (HTTP client) and the switch’s VLAN interface IP address
are in the same network segment;
3) If 2) is not met, HTTP client should connect to an IP address of the switch via
other devices, such as a router.
Similar to management via Telnet, as soon as the host succeeds to ping an IP
address of the switch and to type the right login password, it can access the switch via
HTTP. The configuration list is as below:
Step 1: Configure the IP addresses for the switch and start the HTTP function on the
switch.
For configuring the IP address on the switch through out-of-band management, see
the relevant chapter.
To enable the WEB configuration, users should type the CLI command ip http
server in the global mode as below:
Switch
>en
Switch#config
Switch(Config)#ip http server
Page 25
25
Step 2: Run HTTP protocol on the host.
Open the Web browser on the host and type the IP address of the switch. Or run
directly the HTTP protocol on the Windows. For example, the IP address of the switch is
“10.1.128.251”.
Fig 1-9 Run HTTP Protocol
When accessing a switch with IPv6 address, it is recommended to use the Firefox
browser with 1.5 or later version. For example, if the IPv6 address of the switch is
“3ffe:506:1:2::3”, enter the switch address at the address bar: http://[3ffe:506:1:2::3],
where the address should be in the square brackets.
Step 3: Logon to the switch
To logon to the HTTP configuration interface, valid login user name and password
are required; otherwise the switch will reject HTTP access. This is a method to protect
the switch from the unauthorized access. Consequently, in order to configure the switch
via HTTP, username and password for authorized HTTP users must be configured with
the following command in the global mode:
username <username> password <show_flag> <password>.
Suppose an authorized user in the switch has a username as “test”, and password
as “test”. The configuration procedure is as below:
Switch
>en
Switch#config
Switch(Config)# username test password 0 test
The Web login interface is as below:
Page 26
26
Fig 1-10 Web Login Interface
Input the right username and password, and then the main Web configuration
interface is shown as below.
Fig 1-11 Main Web Configuration Interface
Page 27

1.2 Management Interface
1.2.1 CLI Interface
CLI interface is familiar to most users. As aforementioned, out-of-band management
and Telnet login are all performed through CLI interface to manage the switch.
CLI Interface is supported by Shell program, which consists of a set of configuration
commands.Those commands are categorized according to their functions in switch
configuration and management. Each category represents a different configuration mode.
The Shell for the switch is described below:
z Configuration Modes
z Configuration Syntax
z Shortcut keys
z Help function
z Input verification
z Fuzzy match support

1.2.2.1 User Mode
On entering the CLI interface, entering user entry system first. If as common user, it
is defaulted to User Mode. The prompt shown is “Switch>“, the symbol “>“ is the prompt
for User Mode. When disable command is run under Admin Mode, it will also return to
the User Mode.
Under User Mode, no configuration to the switch is allowed, only clock time and
version information of the switch can be queries.
1.2.2.2 Admin Mode
To enter Admin Mode sees the following: In user entry system, if as Admin user, it is
defaulted to Admin Mode. Admin Mode prompt “Switch#” can be entered under the User
Mode by running the enable command and entering corresponding access levels admin
user password, if a password has been set. Or, when exit command is run under Global
Mode, it will also return to the Admin Mode. ES4700 series also provides a shortcut key
sequence "Ctrl+z”, this allows an easy way to exit to Admin Mode from any configuration
mode (except User Mode).
Under Admin Mode, when disable command is run, it will return to User Mode. When
exit command is run, it will exit the entry and enter user entry system direct. Next users
can reenter the system on entering corresponding user name and password.
Under Admin Mode, the user can query the switch configuration information,
connection status and traffic statistics of all ports; and the user can further enter the
Global Mode from Admin Mode to modify all configurations of the switch. For this reason,
a password must be set for entering Admin mode to prevent unauthorized access and
malicious modification to the switch.
1.2.2.3 Global Mode
Type the config command under Admin Mode will enter the Global Mode prompt
“Switch(Config)#”. Use the exit command under other configuration modes such as
Interface Mode, VLAN mode will return to Global Mode.
The user can perform global configuration settings under Global Mode, such as MAC
Table, Port Mirroring, VLAN creation, IGMP Snooping start, GVRP and STP, etc. And the
user can go further to Interface Mode for configuration of all the interfaces.
1.2.2.4 Interface Mode
Use the interface command under Global Mode can enter the interface mode
specified. ES4700 series provides three interface type: VLAN interface, Ethernet port and

1.2.3 Configuration Syntax
ES4700 series provides various configuration commands. Although all the
commands are different, they all abide by the syntax for ES4700 series configuration
commands. The general command format of ES4700 series is shown below:
cmdtxt <variable> { enum1 | … | enumN } [option]
Conventions: cmdtxt in bold font indicates a command keyword; <variable> indicates a
variable parameter; {enum1 | … | enumN } indicates a mandatory parameter that should
be selected from the parameter set enum1~enumN; and the square bracket ([ ]) in
[option] indicate an optional parameter. There may be combinations of “< >“, “{ }” and
Page 31
31
“[ ]” in the command line, such as [<variable>],{enum1 <variable>| enum2}, [option1

“help” command and the “?”.
Access to Help Usage and function
Help Under any command line prompt, type in “help” and press Enter will
get a brief description of the associated help system.
“?” 1. Under any command line prompt, enter “?” to get a command
list of the current mode and related brief description.
2. Enter a “?” after the command keyword with a embedded
space. If the position should be a parameter, a description of
that parameter type, scope, etc, will be returned; if the position
should be a keyword, then a set of keywords with brief
description will be returned; if the output is “<cr>“, then the
command is complete, press Enter to run the command.
3. A “?” immediately following a string. This will display all the
commands that begin with that string.
1.2.6 Input verification
Returned Information: success
All commands entered through keyboards undergo syntax check by the Shell.
Nothing will be returned if the user entered a correct command under corresponding
modes and the execution is successful.
Returned Information: error
Output error message Explanation
Unrecognized command or illegal
parameter!
The entered command does not exist, or there
is error in parameter scope, type or format.
Ambiguous command At least two interpretations is possible basing on
the current input.

syntax error : missing '"' before the
end of command line!
Quotation marks are not used in pairs.
1.2.7 Fuzzy match support
ES4700 series Shell support fuzzy match in searching command and keyword. Shell
will recognize commands or keywords correctly if the entered string causes no conflict.
For example:
1. For command “show interfaces status ethernet 1/1”, typing “sh in status e 1/1” will
work
2. However, for command “show running-config”, the system will report a “> Ambiguous
command!” error if only “show r” is entered, as Shell is unable to tell whether it is
“show rom” or “show running-config”. Therefore, Shell will only recognize the
command if “sh ru” is entered.

Usage Guide: After a set of configuration with desired functions, the setting should be
saved to the Flash memory, so that the system can revert to the saved configuration
automatically in the case of accidentally powered down or power failure. This is the
equivalent to the copy running-config startup-config command.
2.2 Commands for Maintenance and Debug
When the users configures the switch, they will need to verify whether the
configurations are correct and the switch is operating as expected, and in network failure,
the users will also need to diagnostic the problem. ES4700 series provides various debug
commands including ping, telnet, show and debug, etc. to help the users to check system
configuration, operating status and locate problem causes.
2.2.1 Ping
Ping command is mainly used for sending ICMP query packet from the switches to
Page 50
50
remote devices, also for check the accessibility between the switch and the remote
device. Refer to the Ping command chapter in the Command Manual for explanations of
various parameters and options of the Ping command.
2.2.2 Ping6
Ping6 command is mainly used by the switch to send ICMPv6 query packet to the
remote equipment, verifying the accessibility between the switch and the remote
equipment. Options and explanations of the parameters of the Ping6 command please
refer to Ping6 command chapter in the command manual.
2.2.3 Telnet
2.2.3.1 Introduction to Telnet
Telnet is a simple remote terminal protocol for remote login. Using Telnet, the user
can login to a remote host with its IP address of hostname from his own workstation.
Telnet can send the user’s keystrokes to the remote host and send the remote host
output to the user’s screen through TCP connection. This is a transparent service, as to
the user, the keyboard and monitor seems to be connected to the remote host directly.
Telnet employs the Client-Server mode, the local system is the Telnet client and the
remote host is the Telnet server. ES4700 series can be either the Telnet Server or the
Telnet client.
When ES4700 series is used as the Telnet server, the user can use the Telnet client
program included in Windows or the other operation systems to login to ES4700 series,
as described earlier in the In-band management section. As a Telnet server, ES4700
series allows up to 5 telnet client TCP connections.
And as Telnet client, use telnet command under Admin Mode allow the user to login
to the other remote hosts. ES4700 series can only establish TCP connection to one
remote host. If a connection to another remote host is desired, the current TCP
connection must be dropped.

2.2.3.3 Command For Telnet
2.2.3.3.1 telnet
Command: telnet {<ip-addr> | <ipv6-addr> | host <hostname>} [<port>]
Function: Log on the remote host by Telnet
Parameter:<ip-addr> is the IP address of the remote host,shown in dotted decimal
notation;<ipv6-addr> is the IPv6 address of the remote host;<hostname> is the name of
the remote host,containing max 30 characters;<port> is the port number,ranging
between 0~65535.
Command Mode: Admin Mode
Usage Guide: This command is used when the switch is applied as Telnet client, for
logging on remote host to configure. When a switch is applied as a Telnet client, it can
only establish one TCP connection with the remote host. To connect to another remote
host, the current TCP connection must be disconnected with a hotkey “CTRL+ |”. To
telnet a host name, mapping relationship between the host name and the IP/IPv6
address should be previously configured. For required commands please refer to ip host
and ipv6 host. In case a host corresponds to both an IPv4 and an IPv6 addresses, the
IPv6 should be preferred when telneting this host name.
Command Explanation

2.2.4 SSH
2.2.4.1 Introduction to SSH
SSH (Secure Shell) is a protocol which ensures a secure remote access connection
to network devices. It is based on the reliable TCP/IP protocol. By conducting the
mechanism such as key distribution, authentication and encryption between SSH server
and SSH client, a secure connection is established. The information transferred on this
connection is protected from being intercepted and decrypted. The switch meets the
requirements of SSH2.0. It supports SSH2.0 client software such as SSH Secure Client
and putty. Users can run the above software to manage the switch remotely.
The switch presently supports RSA authentication, 3DES cryptography protocol and
SSH user password authentication etc.
2.2.4.2 SSH Server Configuration Task List

2.2.4.3 Command for SSH
2.2.4.3.1 ssh-server authentication-retries
Command:ssh-server authentication-retries < authentication-retries >
no ssh-server authentication-retries
Function: Configure the number of times for retrying SSH authentication; the “no
ssh-server authentication-retries” command restores the default number of times for
retrying SSH authentication.
Parameter: < authentication-retries > is the number of times for retrying authentication;
valid range is 1 to 10.
Command mode: Global Mode
Default: The number of times for retrying SSH authentication is 3 by default.
Example: Set the number of times for retrying SSH authentication to 5.
Switch(Config)#ssh-server authentication-retries 5
2.2.4.3.2 ssh-server enable

no ssh-server enable
Function: Enable SSH function on the switch; the “no ssh-server enable” command
disables SSH function.
Command mode: Global Mode
Default: SSH function is disabled by default.
Usage Guide: In order that the SSH client can log on the switch, the users need to
configure the SSH user and enable SSH function on the switch.
Example: Enable SSH function on the switch.
Switch(Config)#ssh-server enable
2.2.4.3.3 ssh-server host-key create rsa
Command: ssh-server host-key create rsa [modulus < modulus >]
Function: Generate new RSA host key
Parameter: modulus is the modulus which is used to compute the host key; valid range
is 768 to 2048. The default value is 1024.
Command mode: global Mode
Default: The system uses the key generated when the ssh-server is started at the first
Page 55
55
time.
Usage Guide: This command is used to generate the new host key. When SSH client
logs on the server, the new host key is used for authentication. After the new host key is
generated and “write” command is used to save the configuration, the system uses this
key for authentication all the time. Because it takes quite a long time to compute the
new key and some clients are not compatible with the key generated by the modulus
2048, it is recommended to use the key which is generated by the default modulus
1024.
Example: Generate new host key.
Switch(Config)#ssh-server host-key create rsa

2.2.5 Traceroute
Trace route command is for testing the gateways through which the data packets
travels from the source device to the destination device, so to check the network
accessibility and locate the network failure.
Execution procedure of the Trace route command consists of: first a data packet with
TTL at 1 is sent to the destination address, if the first hop returns an ICMP error message
to inform this packet can not be sent (due to TTL timeout), a data packet with TTL at 2 will
be sent. Also the send hop may be a TTL timeout return, but the procedure will carries on
till the data packet is sent to its destination. These procedures is for recording every
source address which returned ICMP TTL timeout message, so to describe a path the IP
data packets traveled to reach the destination
2.2.6 Traceroute6
The Traceroute6 function is used on testing the gateways passed through by the
data packets from the source equipment to the destination equipment, to verify the
accessibility and locate the network failure. The principle of the Traceroute6 under IPv6 is
the same as that under IPv4, which adopts the hop limit field of the ICMPv6 and IPv6
header. First, Traceroute6 sends an IPv6 datagram (including source address,
destination address and packet sent time) whose HOPLIMIT is set to 1. When first route
on the path receives this datagram, it minus the HOPLIMIT by 1 and the HOPLIMIT is
now 0. So the router will discard this datagram and returns with a 「ICMPv6 time
Page 57
57
exceeded」 message (including the source address of the IPv6 packet, all content in the
IPv6 packet and the IPv6 address of the router). Upon receiving this message, the
Traceroute6 sends another datagram of which the HOPLIMIT is increased to 2 so to
discover the second router. Plus 1 to the HOPLIMIT every time to discover another router,
the Traceroute6 repeat this action till certain datagram reaches the destination.
Traceroute6 Options and explanations of the parameters of the Traceroute6
command please refer to traceroute6 command chapter in the command manual.

2.2.9 System log
2.2.9.1 System Log Introduction
The system log takes all information output under it control, while making detailed
catalogue, so to select the information effectively. Combining with Debug programs, it will
provide a powerful support to the network administrator and developer in monitoring the
network operation state and locating the network failures.
The switch system log has following characteristics
z Log output from four directions (or log channels) of the Console, Telnet terminal
and monitor, log buffer zone, and log host.
z The log information is classified to four level of severities by which the
information will be filtered
z According to the severity level the log information can be auto outputted to
corresponding log channel.
2.2.9.1.1 Log Output Channel
So far the system log can be outputted the log information through four channels
z Through Console port to the local console
z Output the log information to remote Telnet terminal or monitor, this function is
good for remote maintenance.
z Assign a proper log buffer zone inside the switch, for record the log information
permanently or temporarily
z Configure the log host, the log system will directly send the log information to
the log host, and save it in files to be viewed at any time
Among above log channels, users rarely use the console monitor, but will commonly
choose the Telnet terminal to monitor the system operation status. However information
outputted from these channels are of low traffic capacity and can not be recorded for later
view. The other two channels---the log buffer zone and log host channel are two
important channels
SDRAM (Synchronous Dynamic Random Access Memory) and NVRAM (Non
Vulnerable Random Access Memory) is provided inside the switch as two part of the log
buffer zone, The two buffer zone record the log information in a circuit working pattern,
namely when log information need to be recorded exceeds the buffer size, the oldest log
information will be erased and replaced by the new log information, information saved in
NVRAM will stay permanently while those in SDRAM will lost when the system restarts or
encounter an power failure. Information in the log buffer zone is critical for monitoring the
Page 64
64
system operation and detecting abnormal states.
Note: the NVRAM log buffer may not exist on some switches, which only
have the SDRAM log buffer zone
It is recommended to use the system log server. By configuring the log host
on the switch, the log can be sent to the log server for future examination
2.2.9.1.2 Format And Severity Of The Log Information
The log information format is compatible with the BSD syslog protocol, so we can
record and analyze the log by the systlog (system log protect session) on the
UNIX/LINUX, as well as syslog similar applications on PC.
The log information is classified into eight classes by severity or emergency
procedure. One level per value and the higher the emergency level the log information
has, the smaller its value will be. For example, the level of critical is 2, and warning is 4,
debugging is leveled at 7, so the critical is higher than warnings which no doubt is high
than debugging. The rule applied in filtering the log information by severity level is that:
only the log information with level equal to or higher than the threshold will be outputted.
So when the severity threshold is set to debugging, all information will be outputted and if
set to critical, only critical, alerts and emergencies will be outputted.
Follow table summarized the log information severity level and brief description.
Note: these severity levels are in accordance with the standard UNIX/LINUX syslog

Right now the switch can generate information of following four levels
z Restart the switch, mission abnormal, hot plug on the CHASSIS switch chips are
classified critical
z Up/down switch, topology change, aggregate port state change of the interface
are classified warnings
z Outputted information from the CLI command is classified informational
Page 65

z Information from the debugging of CLI command is classified debugging
Log information can be automatically sent to corresponding channels with regard to
respective severity levels. Amongst the debugging information can only be sent to the
monitor. Those with the Informational level can only be sent to current monitor terminal,
such as the information from the Telnet terminal configuration command can only be
transmitted to the Telnet terminal. Warnings information can be sent to all terminal with
also saved in the SDRAM log buffer zone. And the critical information can be save both in
SDRAM and the NVRAM (if exists) besides sent to all terminals. To check the log save in
SDRAM and the NVRAM, we can use the show logging buffered command. To clear the
log save in NVRAM and SDRAM log buffer zone, we can use the clear logging command

2.3 Configurate Switch IP Addresses
All Ethernet ports of ES4700 series is default to Data Link layer ports and perform
layer 2 forwarding. VLAN interface represent a Layer 3 interface function , which can be
assigned an IP address, which is also the IP address of the switch. All VLAN interface
related configuration commands can be configured under VLAN Mode. ES4700 series
provides three IP address configuration methods:
& Manual
& BootP
& DHCP
Manual configuration of IP address is assign an IP address manually for the switch.
In BootP/DHCP mode, the switch operates as a BootP/DHCP client, send broadcast
packets of BootPRequest to the BootP/DHCP servers, and the BootP/DHCP servers
assign the address on receiving the request. In addition, ES4700 series can act as a
Page 69
69
DHCP server, and dynamically assign network parameters such as IP addresses,
gateway addresses and DNS server addresses to DHCP clients DHCP Server
configuration is detailed in later chapters.

2.4 SNMP Configuration
2.4.1 Introduce to SNMP
SNMP (Simple Network Management Protocol) is a standard network management
protocol widely used in computer network management. SNMP is an evolving protocol.
SNMP v1 [RFC1157] is the first version of SNMP which is adapted by vast numbers of
manufacturers for its simplicity and easy implementation; SNMP v2c is an enhanced
version of SNMP v1, which supports layered network management; SNMP v3
strengthens the security by adding USM (User-based Security Mode) and VACM
(View-based Access Control Model).
SNMP protocol provides a simple way of exchange network management
information between two points in the network. SNMP employs a polling mechanism of
message query, and transmits messages through UDP (a connectionless transport layer
protocol). Therefore it is well supported by the existing computer networks.
SNMP protocol employs a station-agent mode. There are two parts in this structure:
NMS (Network Management Station) and Agent. NMS is the workstation on which SNMP
client program is running. It is the core on the SNMP network management. Agent is the
server software runs on the devices which need to be managed. NMS manages all the
managed objects through Agents. The switch supports Agent function.
The communication between NMS and Agent functions in Client/Server mode by
exchanging standard messages. NMS sends request and the Agent responds. There are
seven types of SNMP message:
z Get-Request
Page 72
72
z Get-Response
z Get-Next-Request
z Get-Bulk-Request
z Set-Request
z Trap
z Inform-Request
NMS sends queries to the Agent with Get-Request, Get-Next-Request,
Get-Bulk-Request and Set-Request messages; and the Agent, upon receiving the
requests, replies with Get-Response message. On some special situations, like network
device ports are on Up/Down status or the network topology changes, Agents can send
Trap messages to NMS to inform the abnormal events. Besides, NMS can also be set to
alert to some abnormal events by enabling RMON function. When alert events are
triggered, Agents will send Trap messages or log the event according to the settings.
Inform-Request is mainly used for inter-NMS communication in the layered network
management.
USM ensures the transfer security by well-designed encryption and authentication.
USM encrypts the messages according to the user typed password. This mechanism
ensures that the messages can’t be viewed on transmission. And USM authentication
ensures that the messages can’t be changed on transmission. USM employs DES-CBC
cryptography. And HMAC-MD5 and HMAC-SHA are used for authentication.
VACM is used to classify the users’ access permission. It puts the users with the
same access permission in the same group. Users can’t conduct the operation which is
not authorized.
Introduction to MIB
The network management information accessed by NMS is well defined and
organized in a Management Information Base (MIB). MIB is pre-defined information
which can be accessed by network management protocols. It is in layered and structured
form. The pre-defined management information can be obtained from monitored network
devices. ISO ASN.1 defines a tree structure for MID. Each MIB organizes all the available
information with this tree structure. And each node on this tree contains an OID (Object
Identifier) and a brief description about the node. OID is a set of integers divided by
periods. It identifies the node and can be used to locate the node in a MID tree structure,
shown in the figure below:
Page 73
73
Fig 2-1 ASN.1 Tree Instance
In this figure, the OID of the object A is 1.2.1.1. NMS can locate this object through
this unique OID and gets the standard variables of the object. MIB defines a set of
standard variables for monitored network devices by following this structure.
If the variable information of Agent MIB needs to be browsed, the MIB browse
software needs to be run on the NMS. MIB in the Agent usually consists of public MIB
and private MIB. The public MIB contains public network management information that
can be accessed by all NMS; private MIB contains specific information which can be
viewed and controlled by the support of the manufacturers
MIB-I [RFC1156] is the first implemented public MIB of SNMP, and is replaced by
MIB-II [RFC1213]. MIB-II expands MIB-I and keeps the OID of MIB tree in MIB-I. MIB-II
contains sub-trees which are called groups. Objects in those groups cover all the
functional domains in network management. NMS obtains the network management
information by visiting the MIB of SNMP Agent.
The switch can operate as a SNMP Agent, and supports both SNMP v1/v2c and
SNMP v3. The switch supports basic MIB-II, RMON public MIB and other public MID
such as BRIDGE MIB. Besides, the switch supports self-defined private MIB.
Introduction to RMON
RMON is the most important extended of the standard SNMP. RMON is a set of MIB
definitions, used to define standard network monitor functions and interfaces, enabling
the communication between SNMP management terminals and remote monitors. RMON
provides a highly efficient method to monitor actions inside the subnets.
MID of RMON consists of 10 groups. The switch supports the most frequently used
group 1, 2, 3 and 9:
Statistics: Maintain basic usage and error statistics for each subnet monitored by
the Agent.
History: Record periodical statistic samples available from Statistics.
Page 74
74
Alarm: Allow management console users to set any count or integer for sample
intervals and alert thresholds for RMON Agent records.
Event: A list of all events generated by RMON Agent.
Alarm depends on the implementation of Event. Statistics and History display some
current or history subnet statistics. Alarm and Event provide a method to monitor any
integer data change in the network, and provide some alerts upon abnormal events
(sending Trap or record in logs).

2.4.4 Typical SNMP Configuration Examples
Page 86
86
Fig 2-2 Typical SNMP Configuration
The IP address of the NMS is 1.1.1.5; the IP address of the switch (Agent) is 1.1.1.9
Scenario 1: The NMS network administrative software uses SNMP protocol to obtain
data from the switch.
The configuration on the switch is listed below:
Switch(config)#snmp-server
Switch(Config)#snmp-server community private rw
Switch(Config)#snmp-server community public ro
Switch(Config)#snmp-server securityip 1.1.1.5
The NMS can use “private” as the community string to access the switch with read-write
permission, or use “public” as the community string to access the switch with read-only
permission.
Scenario 2: NMS will receive Trap messages from the switch (Note: NMS may have
community string verification for the Trap messages. In this scenario, the NMS uses a
Trap verification community string of “ectrap”).
The configuration on the switch is listed below:
Switch(config)#snmp-server
Switch(Config)#snmp-server host 1.1.1.5 ectrap
Switch(Config)#snmp-server enable traps
Scenario 3: NMS uses SNMP v3 to obtain information from the switch.
The configuration on the switch is listed below:
Switch(config)#snmp-server
Switch (Config)#snmp-server user tester UserGroup encrypted auth md5 hello
Switch (Config)#snmp-server group UserGroup AuthPriv read max write max notify max
Switch (Config)#snmp-server view max 1 include
1.1.1.5
1.1.1.9
Page 87
87
Scenario 4: NMS wants to receive the v3Trap messages sent by the switch.
The configuration on the switch is listed below:
Switch(config)#snmp-server
Switch(config)#snmp-server host 10.1.1.2 v3 AuthPriv tester
Switch(config)#snmp-server enable traps
2.4.5 SNMP Troubleshooting Help
When users configure the SNMP, the SNMP server may fail to run properly due to
physical connection failure and wrong configuration, etc. Users can troubleshoot the
problems by following the guide below:
Good condition of the physical connection.
Interface and datalink layer protocol is Up (use the “show interface” command), and
the connection between the switch and host can be verified by ping ( use “ping”
command).
The switch enabled SNMP Agent server function (use “snmp-server” command)
Secure IP for NMS (use “snmp-server securityip” command) and community string
(use “snmp-server community” command) are correctly configured, as any of them
fails, SNMP will not be able to communicate with NMS properly.
If Trap function is required, remember to enable Trap (use “snmp-server enable
traps” command): and remember to properly configure the target host IP address
and community string for Trap (use “snmp-server host” command) to ensure Trap
message can be sent to the specified host.
If RMON function is required, RMON must be enabled first (use “rmon enable”
command).
Use “show snmp” command to verify sent and received SNMP messages; Use
“show snmp status” command to SNMP configuration information; Use “debug snmp
packet” to enable SNMP debug function and verify debug information.
If users still can’t solve the SNMP problems, Please contact our technical and
service center.
2.5 Switch Upgrade
ES4700 series provides two ways for switch upgrade: BootROM upgrade and the
TFTP/FTP upgrade under Shell.
2.5.1 Switch System Files
Page 88
88
The system files includes system image file and boot file. The updating of the switch
is to update the two files by overwrite the old files with the new ones.
The system image files refers to the compressed files of the switch hardware drivers,
and software support program, etc, namely what we usually call the IMG update file. The
IMG file can only be saved in the FLASH with a defined name of nos.img
The boot file is for initiating the switch, namely what we usually call the ROM update
file ((It can be compressed into IMG file if it is of large size). The boot file can only be
saved in the ROM in which the file name is defined as boot.rom
The update method of the system image file and the boot file is the same. The
switch supplies the user with two modes of updating: 1. BootROM mode; 2. TFTP and
FTP update at Shell mode. This two update method will be explained in details in
following two sections.
2.5.2 BootROM Upgrade
There are two methods for BootROM upgrade: TFTP and FTP, which can be
selected at BootROM command settings.
Fig 2-3 Typical topology for switch upgrade in BootROM mode
The upgrade procedures are listed below:
Step 1:
As shown in the figure, a PC is used as the console for the switch. A console cable is
used to connect PC to the management port on the switch. The PC should have
FTP/TFTP server software installed and has the img file required for the upgrade.
Step 2:
Press “ctrl+b” on switch boot up until the switch enters BootROM monitor mode. The
operation result is shown below:

[Boot]:
Step 3:
Under BootROM mode, run “setconfig” to set the IP address and mask of the switch
under BootROM mode, server IP address and mask, and select TFTP or FTP upgrade.
Suppose the switch address is 192.168.1.2/24, and PC address is 192.168.1.66/24, and
select TFTP upgrade, the configuration should like:
[Boot]: setconfig
Host IP Address: 10.1.1.1 192.168.1.2
Server IP Address: 10.1.1.2 192.168.1.66
FTP(1) or TFTP(2): 1 2
Network interface configure OK.
[Boot]:
Step 4:
Enable FTP/TFTP server in the PC. For TFTP, run TFTP server program; for FTP, run
FTP server program. Before start downloading upgrade file to the switch, verify the
connectivity between the server and the switch by ping from the server. If ping succeeds,
run “load” command in the BootROM mode from the switch; if it fails, perform
troubleshooting to find out the cause. The following is the configuration for the system
update image file.
[Boot]: load nos.img
Loading...
entry = 0x10010
Page 90
90
size = 0x1077f8
Step 5:
Execute “write nos.img” in BootROM mode. The following saves the system update
image file.
[Boot]: write nos.img
Programming...
Program OK.
[Boot]:
Step 6:
After successful upgrade, execute “run” command in BootROM mode to return to CLI
configuration interface.
[Boot]: run（or reboot）
Other commands in BootROM mode
1. DIR command
Used to list existing files in the FLASH.
[Boot]: dir
boot.rom 327,440 1900-01-01 00: 00: 00 --SH
boot.conf 83 1900-01-01 00: 00: 00 --SH

temp.img 2,431,631 1980-01-01 00: 00: 32 ----
2. CONFIG RUN command
Used to set the IMG file to run upon system start-up, and the configuration file to run
upon configuration recovery.
[Boot]: config run
Boot File: [nos.img] nos1.img
Config File: [boot.conf]
2.5.3 FTP/TFTP Upgrade
2.5.3.1 Introduction to FTP/TFTP
FTP(File Transfer Protocol)/TFTP(Trivial File Transfer Protocol) are both file transfer
protocols that belonging to fourth layer(application layer) of the TCP/IP protocol stack,
Page 91
91
used for transferring files between hosts, hosts and switches. Both of them transfer files
in a client-server model. Their differences are listed below.
FTP builds upon TCP to provide reliable connection-oriented data stream transfer
service. However, it does not provide file access authorization and uses simple
authentication mechanism(transfers username and password in plain text for
authentication). When using FTP to transfer files, two connections need to be established
between the client and the server: a management connection and a data connection. A
transfer request should be sent by the FTP client to establish management connection on
port 21 in the server, and negotiate a data connection through the management
connection.
There are two types of data connections: active connection and passive connection.
In active connection, the client transmits its address and port number for data
transmission to the sever, the management connection maintains until data transfer is
complete. Then, using the address and port number provided by the client, the server
establishes data connection on port 20 (if not engaged) to transfer data; if port 20 is
engaged, the server automatically generates some other port number to establish data
connection.
In passive connection, the client, through management connection, notify the server
to establish a passive connection. The server then create its own data listening port and
inform the client about the port, and the client establishes data connection to the
specified port.
As data connection is established through the specified address and port, there is a
third party to provide data connection service.
TFTP builds upon UDP, providing unreliable data stream transfer service with no
user authentication or permission-based file access authorization. It ensures correct data
transmission by sending and acknowledging mechanism and retransmission of time-out
packets. The advantage of TFTP over FTP is that it is a simple and low overhead file
transfer service.
ES4700 series can operate as either FTP/TFTP client or server. When ES4700
series operates as a FTP/TFTP client, configuration files or system files can be
downloaded from the remote FTP/TFTP servers(can be hosts or other switches) without
affecting its normal operation. And file list can also be retrieved from the server in ftp
client mode. Of course, ES4700 series can also upload current configuration files or
system files to the remote FTP/TFTP servers(can be hosts or other switches). When
ES4700 series operates as a FTP/TFTP server, it can provide file upload and download
service for authorized FTP/TFTP clients, as file list service as FTP server.
Here are some terms frequently used in FTP/TFTP.
ROM: Short for EPROM, erasable read-only memory. EPROM is repalced by FLASH
Page 92
92
memory in ES4700 series.
SDRAM: RAM memory in the switch, used for system software operation and
configuration sequence storage.
FLASH: Flash memory used to save system file and configuration file
System file: including system image file and boot file.
System image file: refers to the compressed file for switch hardware driver and software
support program, usually refer to as IMG upgrade file. In ES4700 series, the system
image file is allowed to save in FLASH only. ES4700 series mandates the name of
system image file to be uploaded via FTP in Global Mode to be nos.img, other IMG
system files will be rejected.
Boot file: refers to the file initializes the switch, also referred to as the ROM upgrade file
(Large size file can be compressed as IMG file). In ES4700 series, the boot file is allowed
to save in ROM only. ES4700 series mandates the name of the boot file to be boot.rom.
Configuration file: including start up configuration file and active configuration file. The
distinction between start up configuration file and active configuration file can facilitate the
backup and update of the configurations.
Start up configuration file: refers to the configuration sequence used in switch start up.
ES4700 series start up configuration file stores in FLASH only, corresponding to the so
called configuration save. To prevent illicit file upload and easier configuration, ES4700
series mandates the name of start up configuration file to be startup-config.
Active configuration file: refers to the active configuration sequence use in the switch.
In ES4700 series, the active configuration file stores in the RAM. In the current version,
the active configuration sequence running-config can be saved from the RAM to FLASH
by write command or copy running-config startup-config command, so that the active
configuration sequence becomes the start up configuration file, which is called
configuration save. To prevent illicit file upload and easier configuration, ES4700 series
mandates the name of active configuration file to be running-config.
Factory configuration file: The configuration file shipped with ES4700 series in the
name of factory-config. Run set default and write, and restart the switch, factory
configuration file will be loaded to overwrite current start up configuration file.
