ESCRIPTION OF SOFTWARE FEATURES
Description of Software Features
The switch provides a wide range of advanced performance enhancing
features. Flow control eliminates the loss of packets due to bottlenecks
caused by port saturation. Broadcast storm suppression prevents broadcast
traffic storms from engulfing the network. Port-based and protocol-based
VLANs, plus support for automatic GVRP VLAN registration provide
traffic security and efficient use of network bandwidth. CoS priority
queueing ensures the minimum delay for moving real-time multimedia data
across the network. While multicast filtering and routing provides support
for real-time network applications. Some of the management features are
briefly described below.
Configuration Backup and Restore – You can save the current
configuration settings to a file on a TFTP server, and later download this
file to restore the switch configuration settings.
Authentication – This switch authenticates management access via the
console port, Telnet or web browser. User names and passwords can be
configured locally or can be verified via a remote authentication server (i.e.,
RADIUS or TACACS+). Port-based authentication is also supported via
the IEEE 802.1x protocol. This protocol uses Extensible Authentication
Protocol over LANs (EAPOL) to request a user name and password from
the 802.1x client, and then uses the EAP between the switch and the
authentication server to verify the client’s right to access the network via an
authentication server.
Other authentication options include HTTPS for secure management
access via the web, SSH for secure management access over a
Telnet-equivalent connection, IP address filtering for SNMP/web/Telnet
management access, and MAC address filtering for port access.
Access Control Lists – ACLs provide packet filtering for IP frames
(based on address, protocol, TCP/UDP port number or TCP control
code) or any frames (based on MAC address or Ethernet type). ACLs can
1-3

NTRODUCTION
by used to improve performance by blocking unnecessary network traffic
or to implement security controls by restricting access to specific network
resources or protocols.
DHCP Server and DHCP Relay – A DHCP ser ver is provided to assign
IP addresses to host devices. Since DHCP uses a broadcast mechanism, a
DHCP server and its client must physically reside on the same subnet.
Since it is not practical to have a DHCP server on every subnet, DHCP
Relay is also supported to allow dynamic configuration of local clients
from a DHCP server located in a different network.
Port Configuration – You can manually configure the speed, duplex
mode, and flow control used on specific ports, or use auto-negotiation to
detect the connection settings used by the attached device. Use the
full-duplex mode on ports whenever possible to double the throughput of
switch connections. Flow control should also be enabled to control
network traffic during periods of congestion and prevent the loss of
packets when port buffer thresholds are exceeded. The switch supports
flow control based on the IEEE 802.3x standard.
Rate Limiting – This feature controls the maximum rate for traffic
transmitted or received on an interface. Rate limiting is configured on
interfaces at the edge of a network to limit traffic into or out of the
network. Traffic that falls within the rate limit is transmitted, while packets
that exceed the acceptable amount of traffic are dropped.
Port Mirroring – The switch can unobtrusively mirror traffic from any
port to a monitor port. You can then attach a protocol analyzer or RMON
probe to this port to perform traffic analysis and verify connection
integrity.
Port Trunking – Ports can be combined into an aggregate connection.
Trunks can be manually set up or dynamically configured using IEEE
802.3ad Link Aggregation Control Protocol (LACP). The additional ports
dramatically increase the throughput across any connection, and provide
1-4
Page 31

ESCRIPTION OF SOFTWARE FEATURES
redundancy by taking over the load if a port in the trunk should fail. The
switch supports up to 6 trunks.
Broadcast Storm Control – Broadcast suppression prevents broadcast
traffic from overwhelming the network. When enabled on a port, the level
of broadcast traffic passing through the port is restricted. If broadcast
traffic rises above a pre-defined threshold, it will be throttled until the level
falls back beneath the threshold.
Static Addresses – A static address can be assigned to a specific interface
on this switch. Static addresses are bound to the assigned interface and will
not be moved. When a static address is seen on another interface, the
address will be ignored and will not be written to the address table. Static
addresses can be used to provide network security by restricting access for
a known host to a specific port.
IEEE 802.1D Bridge – The switch supports IEEE 802.1D transparent
bridging. The address table facilitates data switching by learning addresses,
and then filtering or forwarding traffic based on this information. The
address table supports up to 16K addresses.
Store-and-Forward Switching – The switch copies each frame into its
memory before forwarding them to another port. This ensures that all
frames are a standard Ethernet size and have been verified for accuracy
with the cyclic redundancy check (CRC). This prevents bad frames from
entering the network and wasting bandwidth.
To avoid dropping frames on congested ports, the switch provides 1 MB
for frame buffering. This buffer can queue packets awaiting transmission
on congested networks.
Spanning Tree Protocol – The switch supports these spanning tree
protocols:
Spanning Tree Protocol (STP, IEEE 802.1D) – This protocol adds a level
of fault tolerance by allowing two or more redundant connections to be
created between a pair of LAN segments. When there are multiple physical
1-5
Page 32
I
NTRODUCTION
paths between segments, this protocol will choose a single path and disable
all others to ensure that only one route exists between any two stations on
the network. This prevents the creation of network loops. However, if the
chosen path should fail for any reason, an alternate path will be activated
to maintain the connection.
Rapid Spanning Tree Protocol (RSTP, IEEE 802.1w) – This protocol
reduces the convergence time for network topology changes to about 10%
of that required by the older IEEE 802.1D STP standard. It is intended as
a complete replacement for STP, but can still interoperate with switches
running the older standard by automatically reconfiguring ports to
STP-compliant mode if they detect STP protocol messages from attached
devices.
Multiple Spanning Tree Protocol (MSTP, IEEE 802.1s) – This protocol is
a direct extension of RSTP. It can provide an independent spanning tree
for different VLANs. It simplifies network management, provides for even
faster convergence than RSTP by limiting the size of each region, and
prevents VLAN members from being segmented from the rest of the
group (as sometimes occurs with IEEE 802.1D STP).
Virtual LANs – The switch supports up to 255 VLANs. A Virtual LAN is
a collection of network nodes that share the same collision domain
regardless of their physical location or connection point in the network.
The switch supports tagged VLANs based on the IEEE 802.1Q standard.
Members of VLAN groups can be dynamically learned via GVRP, or ports
can be manually assigned to a specific set of VLANs. This allows the
switch to restrict traffic to the VLAN groups to which a user has been
assigned. By segmenting your network into VLANs, you can:
•Eliminate broadcast storms which severely degrade performance in a
flat network.
•Simplify network management for node changes/moves by remotely
configuring VLAN membership for any port, rather than having to
manually change the network connection.
•Provide data security by restricting all traffic to the originating VLAN,
1-6
Page 33
D
ESCRIPTION OF SOFTWARE FEATURES
except where a connection is explicitly defined via the switch’s routing
service.
•Use private VLANs to restrict traffic to pass only between data ports
and the uplink ports, thereby isolating adjacent ports within the same
VLAN, and allowing you to limit the total number of VLANs that need
to be configured.
Traffic Prioritization – This switch prioritizes each packet based on the
required level of service, using four priority queues with strict or Weighted
Round Robin Queuing. It uses IEEE 802.1p and 802.1Q tags to prioritize
incoming traffic based on input from the end-station application. These
functions can
data and best-effort data.
This switch also supports several common methods of prioritizing layer 3/
4 traffic to meet application requirements. Traffic can be prioritized based
on the priority bits in the IP frame’s Type of Service (ToS) octet. When
these services are enabled, the priorities are mapped to a Class of Service
value by the switch, and the traffic then sent to the corresponding output
queue.
be used to provide independent priorities for delay-sensitive
IP Routing – The switch provides Layer 3 IP routing. To maintain a high
rate of throughput, the switch forwards all traffic passing within the same
segment, and routes only traffic that passes between different
subnetworks. The wire-speed routing provided by this switch lets you
easily link network segments or VLANs together without having to deal
with the bottlenecks or configuration hassles normally associated with
conventional routers.
Routing for unicast traffic is supported with the Routing Information
Protocol (RIP) and the Open Shortest Path First (OSPF) protocol.
RIP – This protocol uses a distance-vector approach to routing. Routes are
determined on the basis of minimizing the distance vector, or hop count,
which serves as a rough estimate of transmission cost.
1-7
Page 34
I
NTRODUCTION
OSPF – This approach uses a link state routing protocol to generate a
shortest-path tree, then builds up its routing table based on this tree. OSPF
produces a more stable network because the participating routers act on
network changes predictably and simultaneously, converging on the best
route more quickly than RIP.
Router Redundancy – Hot Standby Router Protocol (HSRP) and Virtual
Router Redundancy Protocol (VRRP) both use a virtual IP address to
support a primary router and multiple backup routers. The backups can be
configured to take over the workload if the master fails or to load share the
traffic. The primary goal of these protocols is to allow a host device which
has been configured with a fixed gateway to maintain network connectivity
in case the primary gateway goes down.
Address Resolution Protocol – The switch uses ARP and Proxy ARP to
convert between IP addresses and MAC (i.e., hardware) addresses. This
switch supports conventional ARP, which locates the MAC address
corresponding to a given IP address. This allows the switch to use IP
addresses for routing decisions and the corresponding MAC addresses to
forward packets from one hop to the next. You can configure either static
or dynamic entries in the ARP cache.
Proxy ARP allows hosts that do not support routing to determine the
MAC address of a device on another network or subnet. When a host
sends an ARP request for a remote network, the switch checks to see if it
has the best route. If it does, it sends its own MAC address to the host. The
host then sends traffic for the remote destination via the switch, which
uses its own routing table to reach the destination on the other network.
Multicast Filtering – Specific multicast traffic can be assigned to its own
VLAN to ensure that it does not interfere with normal network traffic and
to guarantee real-time delivery by setting the required priority level for the
designated VLAN. The switch uses IGMP Snooping and Query at Layer 2
and IGMP at Layer 3 to manage multicast group registration.
1-8
Page 35
D
ESCRIPTION OF SOFTWARE FEATURES
Multicast Routing – Routing for multicast packets is supported by the
Distance Vector Multicast Routing Protocol (DVMRP) and
Protocol-Independent Multicasting - Dense Mode (PIM-DM). These
protocols work in conjunction with IGMP to filter and route multicast
traffic. DVMRP is a more comprehensive implementation that maintains
its own routing table, but is gradually being replacing by most network
managers with PIM, Dense Mode and Sparse Mode. PIM is a very simple
protocol that uses the routing table of the unicast routing protocol enabled
on an interface. Dense Mode is designed for areas where the probability of
multicast clients is relatively high, and the overhead of frequent flooding is
justified. While Sparse mode is designed for network areas, such as the
Wide Area Network, where the probability of multicast clients is low. This
switch currently supports DVMRP and PIM-DM.

System Defaults
The switch’s system defaults are provided in the configuration file
“Factory_Default_Config.cfg.” To reset the switch defaults, this file
should be set as the startup configuration file (page 3-27).
The following table lists some of the basic system defaults.
The switch includes a built-in network management agent. The agent
offers a variety of management options, including SNMP, RMON and a
web-based interface. A PC may also be connected directly to the switch for
configuration and monitoring via a command line interface (CLI).
Note: The IP address for this switch is unassigned by default. To change
this address, see “Setting an IP Address” on page 2-7.
The switch’s HTTP web agent allows you to configure switch parameters,
monitor port connections, and display statistics using a standard web
browser such as Netscape Navigator version 6.2 and higher or Microsoft
IE version 5.0 and higher. The switch’s web management interface can be
accessed from any computer attached to the network.

The CLI program can be accessed by a direct connection to the RS-232
serial console port on the switch, or remotely by a Telnet connection over
the network.
The switch’s management agent also supports SNMP (Simple Network
Management Protocol). This SNMP agent permits the switch to be
managed from any system in the network using network management
software such as HP OpenView.

ONNECTING TO THE SWITCH
Required Connections
The switch provides an RS-232 serial port that enables a connection to a
PC or terminal for monitoring and configuring the switch. A null-modem
console cable is provided with the switch.
Attach a VT100-compatible terminal, or a PC running a terminal
emulation program to the switch. You can use the console cable provided
with this package, or use a null-modem cable that complies with the wiring
assignments shown in the Installation Guide.
To connect a terminal to the console port, complete the following steps:
1. Connect the console cable to the serial port on a terminal, or a PC
running terminal emulation software, and tighten the captive retaining
screws on the DB-9 connector.
2. Connect the other end of the cable to the RS-232 serial port on the
switch.
3. Make sure the terminal emulation software is set as follows:
•Select the appropriate serial port (COM port 1 or COM port 2).
•Set to any of the following baud rates: 9600, 19200, 38400, 57600,
115200
(Note: Set to 9600 baud if want to view all the system initialization
messages.)
•Set the data format to 8 data bits, 1 stop bit, and no parity.
•Set flow control to none.
•Set the emulation mode to VT100.
•When using HyperTerminal, select Terminal keys, not Windows

Remote Connections
Prior to accessing the switch’s onboard agent via a network connection,
you must first configure it with a valid IP address, subnet mask, and default
gateway using a console connection, DHCP or BOOTP protocol.
The IP address for this switch is unassigned by default. To manually
configure this address or enable dynamic address assignment via DHCP or
BOOTP, see “Setting an IP Address” on page 2-7.
Notes: 1. This switch supports four concurrent Telnet/SSH sessions.
2.Each VLAN group can be assigned its own IP interface address
(page 2-7). You can manage the switch via any of these
addresses.
After configuring the switch’s IP parameters, you can access the onboard
configuration program from anywhere within the attached network. The
onboard configuration program can be accessed using Telnet from any
computer attached to the network. The switch can also be managed by any
computer using a web browser (Internet Explorer 5.0 or above, or
Netscape Navigator 6.2 or above), or from a network computer using
SNMP network management software.
Note: The onboard program only provides access to basic configuration
functions. To access the full range of SNMP management
functions, you must use SNMP-based network management
software.
Basic Configuration
Console Connection
The CLI program provides two different command levels — normal
access level (Normal Exec) and privileged access level (Privileged Exec).
The commands available at the Normal Exec level are a limited subset of
2-5
Page 46
I
NITIAL CONFIGURATION
those available at the Privileged Exec level and allow you to only display
information and use basic utilities. To fully configure the switch
parameters, you must access the CLI at the Privileged Exec level.
Access to both CLI levels are controlled by user names and passwords.
The switch has a default user name and password for each level. To log
into the CLI at the Privileged Exec level using the default user name and
password, perform these steps:
1. To initiate your console connection, press <Enter>. The “User Access
Verification” procedure starts.
2. At the Username prompt, enter “admin.”
3. At the Password prompt, also enter “admin.” (The password
characters are not displayed on the console screen.)
4. The session is opened and the CLI displays the “Console#” prompt
indicating you have access at the Privileged Exec level.
Setting Passwords
Note: If this is your first time to log into the CLI program, you should
define new passwords for both default user names using the
“username” command, record them and put them in a safe place.
Passwords can consist of up to 8 alphanumeric characters and are case
sensitive. To prevent unauthorized access to the switch, set the passwords
as follows:
1. Open the console interface with the default user name and password
“admin” to access the Privileged Exec level.
2. Type “configure” and press <Enter>.
3. Type “username guest password 0 password,” for the Normal Exec
level, where password is your new password. Press <Enter>.

To end the CLI session, enter [Exit].
You must establish IP address information for the switch to obtain
management access through the network. This can be done in either of the
following ways:
Manual — You have to input the information, including IP address and
subnet mask. If your management station is not in the same IP subnet as
the switch, you will also need to specify the default gateway router.
Dynamic — The switch sends IP configuration requests to BOOTP or
DHCP address allocation servers on the network.
Manual Configuration
You can manually assign an IP address to the switch. You may also need to
specify a default gateway that resides between this device and management
stations that exist on another network segment (if routing is not enabled
on this switch). Valid IP addresses consist of four decimal numbers, 0 to
255, separated by periods. Anything outside this format will not be
accepted by the CLI program.
Note: The IP address for this switch is unassigned by default.
Before you can assign an IP address to the switch, you must obtain the
following information from your network administrator:
2-7
Page 48
I
NITIAL CONFIGURATION
•IP address for the switch
•Default gateway for the network
•Network mask for this network
To assign an IP address to the switch, complete the following steps:
1. From the Privileged Exec level global configuration mode prompt,
type “interface vlan 1” to access the interface-configuration mode.
Press <Enter>.
2. Type “ip address ip-address netmask,” where “ip-address” is the switch
IP address and “netmask” is the network mask for the network. Press
<Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press
<Enter>.
4. To set the IP address of the default gateway for the network to which
the switch belongs, type “ip default-gateway gateway,” where “gateway”
is the IP address of the default gateway. Press <Enter>.
If you select the “bootp” or “dhcp” option, IP will be enabled but will not
function until a BOOTP or DHCP reply has been received. You therefore
need to use the “ip dhcp restart client” command to start broadcasting
service requests. Requests will be sent periodically in an effort to obtain IP
configuration information. (BOOTP and DHCP values can include the IP
address, subnet mask, and default gateway.)
2-8
Page 49

ASIC CONFIGURATION
If the “bootp” or “dhcp” option is saved to the startup-config file (step 6),
then the switch will start broadcasting service requests as soon as it is
powered on.
To automatically configure the switch by communicating with BOOTP or
DHCP address allocation servers on the network, complete the following
steps:
1. From the Global Configuration mode prompt, type “interface vlan 1”
to access the interface-configuration mode. Press <Enter>.
2. At the interface-configuration mode prompt, use one of the following
commands:
•To obtain IP settings via DHCP, type “ip address dhcp” and press
<Enter>.
•To obtain IP settings via BOOTP, type “ip address bootp” and
press <Enter>.
3. Type “end” to return to the Privileged Exec mode. Press <Enter>.
4. Type “ip dhcp restart client” to begin broadcasting service requests.
Press <Enter>.
5. Wait a few minutes, and then check the IP configuration settings by
typing the “show ip interface” command. Press <Enter>.

Enabling SNMP Management Access
The switch can be configured to accept management commands from
Simple Network Management Protocol (SNMP) applications such as HP
OpenView. You can configure the switch to (1) respond to SNMP requests
or (2) generate SNMP traps.
When SNMP management stations send requests to the switch (either to
return information or to set a parameter), the switch provides the
requested data or sets the specified parameter. The switch can also be
configured to send information to SNMP managers (without being
requested by the managers) through trap messages, which inform the
manager that certain events have occurred.
Community Strings
Community strings are used to control management access to SNMP
stations, as well as to authorize SNMP stations to receive trap messages
from the switch. You therefore need to assign community strings to
specified users or user groups, and set the access level.
2-10
Page 51
B
ASIC CONFIGURATION
The default strings are:
•public - with read-only access. Authorized management stations are
only able to retrieve MIB objects.
•private - with read-write access. Authorized management stations are
able to both retrieve and modify MIB objects.
Note: If you do not intend to utilize SNMP, we recommend that you
delete both of the default community strings. If there are no
community strings, then SNMP management access to the switch
is disabled.
To prevent unauthorized access to the switch via SNMP, it is
recommended that you change the default community strings.
To configure a community string, complete the following steps:
1. From the Privileged Exec level global configuration mode prompt,
type “snmp-server community string mode,” where “string” is the
community access string and “mode” is rw (read/write) or ro (read
only). Press <Enter>. (Note that the default mode is read only.)
2. To remove an existing string, simply type “no snmp-server community
string,” where “string” is the community access string to remove. Press
<Enter>.
Console(config)#snmp-server community admin rw
Console(config)#snmp-server community private
Console(config)#
Trap Receivers
You can also specify SNMP stations that are to receive traps from the
switch.
To configure a trap receiver, complete the following steps:
2-11
Page 52
I
NITIAL CONFIGURATION
1. From the Privileged Exec level global configuration mode prompt,
type “snmp-server host host-address community-string,” where
“host-address” is the IP address for the trap receiver and
“community-string” is the string associated with that host. Press
<Enter>.
2. In order to configure the switch to send SNMP notifications, you must
enter at least one snmp-server enable traps command. Type
“snmp-server enable traps type,” where “type” is either authentication
or link-up-down. Press <Enter>.
Configuration commands only modify the running configuration file and
are not saved when the switch is rebooted. To save all your configuration
changes in nonvolatile storage, you must copy the running configuration
file to the start-up configuration file using the “copy” command.
To save the current configuration settings, enter the following command:
1. From the Privileged Exec mode prompt, type “copy running-config
startup-config” and press <Enter>.
2. Enter the name of the start-up file. Press <Enter>.
Console#copy running-config startup-config

ANAGING SYSTEM FILES
Managing System Files
The switch’s flash memory supports three types of system files that can be
managed by the CLI program, web interface, or SNMP. The switch’s file
system allows files to be uploaded and downloaded, copied, deleted, and
set as a start-up file.
The three types of files are:
•Configuration — This file stores system configuration information
and is created when configuration settings are saved. Saved
configuration files can be selected as a system start-up file or can be
uploaded via TFTP to a server for backup. A file named
“Factory_Default_Config.cfg” contains all the system default settings
and cannot be deleted from the system. See “Saving or Restoring
Configuration Settings” on page 3-26 for more information.
•Operation Code — System software that is executed after boot-up,
also known as run-time code. This code runs the switch operations and
provides the CLI and web management interfaces. See “Managing
Firmware” on page 3-24 for more information.
•Diagnostic Code — Software that is run during system boot-up, also
known as POST (Power On Self-Test).
Due to the size limit of the flash memory, the switch supports only two
operation code files. However, you can have as many diagnostic code files
and configuration files as available flash memory space allows.
In the system flash memory, one file of each type must be set as the
start-up file. During a system boot, the diagnostic and operation code files
set as the start-up file are run, and then the start-up configuration file is
loaded.
2-13
Page 54
I
NITIAL CONFIGURATION
Note that configuration files should be downloaded using a file name that
reflects the contents or usage of the file settings. If you download directly
to the running-config, the system will reboot, and the settings will have to
be copied from the running-config to a permanent file.

Using the Web Interface
This switch provides an embedded HTTP web agent. Using a web browser
you can configure the switch and view statistics to monitor network
activity. The web agent can be accessed by any computer on the network
using a standard web browser (Internet Explorer 5.0 or above, or Netscape
Navigator 6.2 or above).
Note: You can also use the Command Line Interface (CLI) to manage
the switch over a serial connection to the console port or via
Telnet.For more information on using the CLI, refer to Chapter 4
“Command Line Interface.”
Prior to accessing the switch from a web browser, be sure you have first
performed the following tasks:
1. Configure the switch with a valid IP address, subnet mask, and default
gateway using an out-of-band serial connection, BOOTP or DHCP
protocol. (See“Setting an IP Address” on page 2-7.)
3
2. Set user names and passwords using an out-of-band serial connection.
Access to the web agent is controlled by the same user names and
passwords as the onboard configuration program. (See “Setting
Passwords” on page 2-6.)
3. After you enter a user name and password, you will have access to the
system configuration program.
Notes: 1. You are allowed three attempts to enter the correct password;
3-1
Page 56
C
ONFIGURING THE SWITCH
on the third failed attempt the current connection is
terminated.
2. If you log into the web interface as guest (Normal Exec level),
you can view the configuration settings or change the guest
password. If you log in as “admin” (Privileged Exec level), you
can change the settings on any page.
3. If the path between your management station and this switch
does not pass through any device that uses the Spanning Tree
Algorithm, then you can set the switch port attached to your
management station to fast forwarding (i.e., enable Admin
Edge Port) to improve the switch’s response time to
management commands issued through the web interface. See
“Configuring Interface Settings” on page 3-140.

ONFIGURING THE SWITCH
Setting the Switch’s IP Address
This section describes how to configure an initial IP interface for
management access over the network. The IP address for this switch is
unassigned by default. To manually configure an address, you need to
change the switch’s default settings (IP address 0.0.0.0 and netmask
255.0.0.0) to values that are compatible with your network. You may also
need to a establish a default gateway between the switch and management
stations that exist on another network segment (if routing is not enabled
on this switch).
You can manually configure a specific IP address, or direct the device to
obtain an address from a BOOTP or DHCP server. Valid IP addresses
consist of four decimal numbers, 0 to 255, separated by periods. Anything
outside this format will not be accepted by the CLI program.
Command Usage
•This section describes how to configure a single local interface for
initial access to the switch. To configure multiple IP interfaces on this
switch, you must set up an IP interface for each VLAN (page 3-252).
•To enable routing between the different interfaces on this switch, you
must enable IP routing (page 3-250).
•To enable routing between the interfaces defined on this switch and
external network interfaces, you must configure static routes (page
3-269) or use dynamic routing; i.e., either RIP (page 3-273) or OSPF
(page 3-285).
•The precedence for configuring IP interfaces is the IP / General /
Routing Interface menu (page 3-252), static routes (page 3-269), and
then dynamic routing.
Command Attributes
•VLAN – ID of the configured VLAN (1-4094, no leading zeroes). By
default, all ports on the switch are members of VLAN 1. However, the
management station can be attached to a port belonging to any VLAN,
3-20
Page 75
B
ASIC CONFIGURATION
as long as that VLAN has been assigned an IP address.
•IP Address Mode – Specifies whether IP functionality is enabled via
manual configuration (Static), Dynamic Host Configuration Protocol
(DHCP), or Boot Protocol (BOOTP). If DHCP/BOOTP is enabled,
IP will not function until a reply has been received from the server.
Requests will be broadcast periodically by the switch for an IP address.
(DHCP/BOOTP values can include the IP address, subnet mask, and
default gateway.)
•IP Address – Address of the VLAN interface through which the
management station is attached. Valid IP addresses consist of four
numbers, 0 to 255, separated by periods. (Default: 0.0.0.0)
•Subnet Mask – This mask identifies the host address bits used for
routing to specific subnets. (Default: 255.0.0.0)
•Default Gateway – IP address of the gateway router between this
device and management stations that exist on other network segments.
(Default: 0.0.0.0)
•MAC Address – The physical layer address for this switch.
Manual Configuration
Web – Click IP, General, Routing Interface. Select the VLAN through
which the management station is attached, set the IP Address Mode to

Configuring Event Logging
The switch allows you to control the logging of error messages, including
the type of events that are recorded in switch memory, logging to a remote
System Log (syslog) server, and displays a list of recent event messages.
System Log Configuration
The system allows you to enable or disable event logging, and specify
which levels are logged to RAM or flash memory.
Severe error messages that are logged to flash memory are permanently
stored in the switch to assist in troubleshooting network problems. Up to
4096 log entries can be stored in the flash memory, with the oldest entries
being overwritten first when the available log memory (256 kilobytes) has
been exceeded.
The System Logs page allows you to configure and limit system messages
that are logged to flash or RAM memory. The default is for event levels 0
to 3 to be logged to flash and levels 0 to 7 to be logged to RAM.
Command Attributes
•System Log Status – Enables/disables the logging of debug or error
messages to the logging process.
•Flash Level – Limits log messages saved to the switch’s permanent
flash memory for all levels up to the specified level. For example, if

Remote Log Configuration
The Remote Logs page allows you to configure the logging of messages
that are sent to syslog servers or other management stations. You can also
limit the event messages sent to only those messages at or above a
specified level.
Command Attributes
•Remote Log Status – Enables/disables the logging of debug or error
messages to the remote logging process. (Default: enabled)
•Logging Facility – Sets the facility type for remote logging of syslog
messages. There are eight facility types specified by values of 16 to 23.
The facility type is used by the syslog server to dispatch log messages
to an appropriate service.
The attribute specifies the facility type tag sent in syslog messages. (See
RFC 3164.) This type has no effect on the kind of messages reported
by the switch. However, it may be used by the syslog server to process
messages, such as sorting or storing messages in the corresponding
database. (Range: 16-23, Default: 23)
•Logging Trap – Limits log messages that are sent to the remote syslog
server for all levels up to the specified level. For example, if level 3 is

Setting the System Clock
Simple Network Time Protocol (SNTP) allows the switch to set its internal
clock based on periodic updates from a time server (SNTP or NTP).
Maintaining an accurate time on the switch enables the system log to
record meaningful dates and times for event entries. You can also manually
set the clock using the CLI. (See “calendar set” on page 3-76.) If the clock
is not set, the switch will only record the time from the factory default set
at the last bootup.
This switch acts as an SNTP client in two modes:
Unicast – The switch periodically sends a request for a time update to a
configured time server. You can configure up to three time server IP
3-33
Page 88
C
ONFIGURING THE SWITCH
addresses. The switch will attempt to poll each server in the configured
sequence.
Broadcast – The switch sets its clock from a time server in the same subnet
that broadcasts time updates. If there is more than one SNTP server, the
switch accepts the first broadcast it detects and ignores broadcasts from
other servers.
Configuring SNTP
You can configure the switch to send time synchronization requests to
specific time servers (i.e., client mode), update its clock based on
broadcasts from time servers, or use both methods. When both methods
are enabled, the switch will update its clock using information broadcast
from time servers, but will query the specified server(s) if a broadcast is
not received within the polling interval.
Command Attributes
•SNTP Client – Configures the switch to operate as an SNTP unicast
client. This mode requires at least one time server to be specified in the
SNTP Server field.
•SNTP Broadcast Client – Configures the switch to operate as an
SNTP broadcast client. This mode requires no other configuration
settings; the switch will obtain time updates from time server
broadcasts (using the multicast address 224.0.1.1).
•SNTP Poll Interval – Sets the interval between sending requests for
a time update from a time server when set to SNTP Client mode.
(Range: 16-16284 seconds; Default: 16 seconds)
•SNTP Server – In unicast mode, sets the IP address for up to three
time servers. The switch attempts to update the time from the first
server, if this fails it attempts an update from the next server in the
sequence.

Simple Network Management Protocol (SNMP) is a communication
protocol designed specifically for managing devices on a network.
Equipment commonly managed with SNMP includes switches, routers
and host computers. SNMP is typically used to configure these devices for
proper operation in a network environment, as well as to monitor them to
evaluate performance or detect potential problems.
The switch includes an onboard SNMP agent that continuously monitors
the status of its hardware, as well as the traffic passing through its ports. A
network management station can access this information using software
such as HP OpenView. Access rights to the onboard agent are controlled
by community strings. To communicate with the switch, the management
station must first submit a valid community string for authentication. The
options for configuring community strings, trap functions, and restricting
access to clients with specified IP addresses are described in the following
sections.

Filtering Addresses for SNMP Client Access
The switch allows you to create a list of up to 16 IP addresses or IP
address groups that are allowed access to the switch via SNMP
management software (also see page 3-69).
Command Usage
•To specify the clients allowed SNMP access, enter an IP address along
with a subnet mask to identify a specific host or a range of valid
addresses. For example:
-IP address 192.168.1.1 and mask 255.255.255.255 –
Specifies a valid IP address of 192.168.1.1 for a single client.
-IP address 192.168.1.1 and mask 255.255.255.0 –
Specifies a valid IP address group from 192.168.1.0 to
192.168.1.254.
•IP filtering only restricts management access for clients running SNMP
management software such as HP OpenView. It does not affect
management access to the switch using the web interface or Telnet.
•The default setting is null, which allows all IP groups SNMP access to
the switch. If one or more IP addresses are configured, IP filtering is
enabled and only addresses listed in this table will have SNMP access.
Command Attributes
•IP Filter List – Displays a list of the IP address/subnet mask entries
currently configured for SNMP access.
•IP address – Specifies a new IP address to add to the IP Filter List.
•Subnet Mask – Specifies a single IP address or group of addresses. If
