�

The Main Menu (page 2-7)

�

Screen structure and navigation (page 2-9)

�

Rebooting the switch (page 2-12)

The menu interface operates through the switch console to provide you with
a subset of switch commands in an easy-to-use menu format enabling you to:

�

Perform a “quick configuration” of basic parameters, such as the IP

addressing needed to provide management access through your network

�

Configure these features:

• Manager and Operator pass­words

• System parameters

• IP addressing

• Time protocol

• Ports

• A network monitoring port

• Spanning Tree operation

• SNMP community names

• IP authorized managers

• VLANs (Virtual LANs) and

GVRP

• Trunk groups

�

View status, counters, and Event Log information

�

Update switch software

�

For a detailed list of menu features, see the “Menu Features List” on page 2-14.

Privilege Levels and Password Security. HP strongly recommends that
you configure a Manager password to help prevent unauthorized access to
your network. A Manager password grants full read-write access to the switch.
An Operator password, if configured, grants access to status and counter,
Event Log, and the Operator level in the CLI. After you configure passwords
on the switch and log off of the interface, access to the menu interface (and
the CLI and web browser interface) will require entry of either the Manager
or Operator password. (If the switch has only a Manager password, then
someone without a password can still gain read-only access.)

2-2

Starting and Ending a Menu Session

Using the Menu Interface

Not e If the switch has neither a Manager nor an Operator password, anyone

having access to the console interface can operate the console with full
manager privileges. Also, if you configure only an Operator password,
entering the Operator password enables full manager privileges.

For more information on passwords, refer to the Access Security Guide for
your switch.

Menu Interaction with Other Interfaces.

�

The menu interface displays the current running-config parameter set-

tings. You can use the menu interface to save configuration changes made
in the CLI only if the CLI changes are in the running config when you save
changes made in the menu interface. (For more on how switch memory
manages configuration changes, see
Configuration”.)

�

A configuration change made through any switch interface overwrites

earlier changes made through any other interface.

�

The Menu Interface and the CLI (Command Line Interface) both use the

switch console. To enter the menu from the CLI, use the

Command Line (CLI) option.)

Starting and Ending a Menu Session

You can access the menu interface using any of the following:

�

A direct serial connection to the switch’s console port, as described in the

installation guide you received with the switch

�

A Telnet connection to the switch console from a networked PC or the

switch’s web browser interface. Telnet requires that an IP address and
subnet mask compatible with your network have already been configured
on the switch.

Not e This section assumes that either a terminal device is already configured and

connected to the switch (see the Installation and Getting Started Guide
shipped with your switch) or that you have already configured an IP address
on the switch (required for Telnet access).

Using the Command Line Interface (CLI)

Overview

Overview

The CLI is a text-based command interface for configuring and monitoring the
switch. The CLI gives you access to the switch’s full set of commands while
providing the same password protection that is used in the web browser
interface and the menu interface.

Accessing the CLI

Like the menu interface, the CLI is accessed through the switch console, and,
in the switch’s factory default state, is the default interface when you start a
console session. You can access the console out-of-band by directly
connecting a terminal device to the switch, or in-band by using Telnet either
from a terminal device or through the web browser interface.

Also, if you are using the menu interface, you can access the CLI by selecting
the Command Line (CLI) option in the Main Menu.

Using the CLI

The CLI offers these privilege levels to help protect the switch from unautho­rized access:

1. Operator

2. Manager

3. Global Configuration

4. Context Configuration

Not e CLI commands are not case-sensitive.

When you use the CLI to make a configuration change, the switch writes the
change to the Running-Config file in volatile memory. This allows you to test
your configuration changes before making them permanent. To make changes
permanent, you must use the write memory command to save them to the

3-2

Using the Command Line Interface (CLI)

Startup Config file in non-volatile memory. If you reboot the switch without
first using write memory, all changes made since the last reboot or write memory
(whichever is later) will be lost. For more on switch memory and saving
configuration changes, see

Chapter 5, “Switch Memory and Configuration”.

Using the CLI

Privilege Levels at Logon

Privilege levels control the type of access to the CLI. To implement this
control, you must set at least a Manager password. Without a Manager

password configured, anyone having serial port, Telnet, or web browser
access to the switch can reach all CLI levels. (For more on setting passwords,

refer to the chapter on usernames and passwords in the Access Security Guide
for your switch.)

When you use the CLI to log on to the switch, and passwords are set, you will
be prompted to enter a password. For example:

Password Prompt

Figure 3-1. Example of CLI Log-On Screen with Password(s) Set

In the above case, you will enter the CLI at the level corresponding to the
password you provide (operator or manager).

If no passwords are set when you log onto the CLI, you will enter at the
Manager level. For example:

HPswitch# _

3-3

Using the Command Line Interface (CLI)

Using the CLI

Caution HP strongly recommends that you configure a Manager password. If a

Manager password is not configured, then the Manager level is not password­protected, and anyone having in-band or out-of-band access to the switch may
be able to reach the Manager level and compromise switch and network
security. Note that configuring only an Operator password does not prevent
access to the Manager level by intruders who have the Operator password.

Pressing the Clear button on the front of the switch removes password
protection. For this reason, it is recommended that you protect the switch
from physical access by unauthorized persons. If you are concerned about
switch security and operation, you should install the switch in a secure
location, such as a locked wiring closet.

Privilege Level Operation

Operator Privileges

Manager Privileges

Figure 3-2. Access Sequence for Privilege Levels

1. Operator Level

2. Manager Level

3. Global Configuration

4. Context Configuration Level

Operator Privileges

At the Operator level you can examine the current configuration and move
between interfaces without being able to change the configuration. A “>”
character delimits the Operator-level prompt. For example:

HPswitch> _ (Example of the Operator prompt.)

When using enable to move to the Manager level, the switch prompts you for
the Manager password if one has already been configured.

3-4

Using the Command Line Interface (CLI)

Using the CLI

Manager Privileges

Manager privileges give you three additional levels of access: Manager, Global
Configuration, and Context Configuration. (See figure.) A “#” character
delimits any Manager prompt. For example:

HPswitch#_ (Example of the Manager prompt.)

�

Manager level: Provides all Operator level privileges plus the ability to

perform system-level actions that do not require saving changes to the
system configuration file. The prompt for the Manager level contains only
the system name and the “#” delimiter, as shown above. To select this
level, enter the enable command at the Operator level prompt and enter
the Manager password, when prompted. For example:

HPswitch> enable (Enter enable at the Operator prompt.)
HPswitch# _ (The Manager prompt.)

�

Global Configuration level: Provides all Operator and Manager level

privileges, and enables you to make configuration changes to any of the
switch’s software features. The prompt for the Global Configuration level
includes the system name and “(config)”. To select this level, enter the
config command at the Manager prompt. For example:

HPswitch# _ (Enter config at the Manager prompt.)
HPswitch(config)#_(The Global Config prompt.)

�

Context Configuration level: Provides all Operator and Manager priv-

ileges, and enables you to make configuration changes in a specific
context, such as one or more ports or a VLAN. The prompt for the Context
Configuration level includes the system name and the selected context.
For example:

HPswitch(eth-1)#

HPswitch(vlan-10)#

The Context level is useful, for example, if you want to execute several
commands directed at the same port or VLAN, or if you want to shorten
the command strings for a specific context area. To select this level, enter
the specific context at the Global Configuration level prompt. For
example, to select the context level for an existing VLAN with the VLAN
ID of 10, you would enter the following command and see the indicated
result:

HPswitch(config)# vlan 10

HPswitch(vlan-10)#

Using the Command Line Interface (CLI)

Using the CLI

Changing Interfaces. If you change from the CLI to the menu interface, or
the reverse, you will remain at the same privilege level. For example, entering
the menu command from the Operator level of the CLI takes you to the
Operator privilege level in the menu interface.

Moving Between the CLI and the Menu Interface. When moving
between interfaces, the switch retains the current privilege level (Manager or
Operator). That is, if you are at the Operator level in the menu and select the
Command Line Interface (CLI) option from the Main Menu, the CLI prompt
appears at the Operator level.

Changing Parameter Settings. Regardless of which interface is used (CLI,
menu interface, or web browser interface), the most recently configured
version of a parameter setting overrides any earlier settings for that parameter.
For example, if you use the menu interface to configure an IP address of “X”

3-7

Using the Command Line Interface (CLI)

Using the CLI

for VLAN 1 and later use the CLI to configure a different IP address of “Y” for
VLAN 1, then “Y” replaces “X” as the IP address for VLAN 1 in the running­config file. If you subsequently execute write memory in the CLI, then the
switch also stores “Y” as the IP address for VLAN 1 in the startup-config file.
(For more on the startup-config and running config files, see
“Switch Memory and Configuration”.)

Listing Commands and Command Options

At any privilege level you can:

�

List all of the commands available at that level

�

List the options for a specific command

Listing Commands Available at Any Privilege Level

At a given privilege level you can list and execute the commands that level
offers, plus all of the commands available at preceding levels. For example,
at the Operator level, you can list and execute only the Operator level
commands. However, at the Manager level, you can list and execute the
commands available at both the Operator and Manager levels.

Chapter 5,

Type “?” To List Available Commands. 1.Typing the

? symbol lists the

commands you can execute at the current privilege level. For example,
typing ? at the Operator level produces this listing:

�

Detailed information on how to use individual commands

Displaying Command-List Help. You can display a listing of command
Help summaries for all commands available at the current privilege level. That
is, when you are at the Operator level, you can display the Help summaries
only for Operator-Level commands. At the Manager level, you can display the
Help summaries for both the Operator and Manager levels, and so on.

Syntax: help

For example, to list the Operator-Level commands with their purposes:

Figure 3-8. Example of Help for a Specific Instance of a Command

Note that trying to list the help for an individual command from a privilege
level that does not include that command results in an error message. For
example, trying to list the help for the interface command while at the global
configuration level produces this result:

Configuration Commands and the Context Configuration Modes

You can execute any configuration command in the global configuration mode
or in selected context modes. However, using a context mode enables you to
execute context-specific commands faster, with shorter command strings.

The Series 5300XL switches offers interface (port or trunk group) and VLAN
context configuration modes:

Port or Trunk-Group Context . Includes port- or trunk-specific
commands that apply only to the selected port(s) or trunk group, plus the
global configuration, Manager, and Operator commands. The prompt for this
mode includes the identity of the selected port(s):

HPswitch(config)# interface e c3-c6

HPswitch(config)# interface e trk1

Pswitch(eth-C5-C8)#

H

HPswitch(eth-Trk1)#

HPswitch(eth-C5-C8)# ?

HPswitch(eth-C5-C8)# ?

Command executed at
configuration level for
entering port or trk1 static
trunk-group context.

Resulting prompt showing

contexts.

Lists the commands you
can use in the port or static
trunk context, plus the
Manager, Operator, and
context commands you
can execute at this level.

Using HP TopTools for Hubs & Switches

HP TopTools for Hubs & Switches is designed for installation on a network
management workstation. For this reason, the HP TopTools system require­ments are different from the system requirements for accessing the switch’s
web browser interface from a non-management PC or workstation. For HP
TopTools requirements, refer to the information provided with HP TopTools
for Hubs & Switches.

This procedure assumes that:

�

You have installed the recommended web browser on a PC or workstation

that serves as your network management station.

�

The networked device you want to access has been assigned an IP address

and (optionally) a DNS name and has been discovered by HP TopTools
for Hubs & Switches. (For more on assigning an IP address, refer to “IP
Configuration” on

page 7-3.)

To establish a web browser session with HP TopTools running, do the
following on the network management station:

TM

1. Make sure the Java

applets are enabled for your web browser. If they
are not, refer to the web browser online Help for specific information on
enabling the Java applets.

2. Do one of the following tasks:

• On the HP TopTools Maps view, double-click on the symbol for the

networking device that you want to access.

• In HP TopTools, in the Topology Information dialog box, in the device

list, double-click on the entry for the device you want to access (IP
address or DNS name).

Not e Passwords you assign in the web browser interface will overwrite previous

passwords assigned in either the web browser interface, the Command
Prompt, or the switch console. That is, the most recently assigned passwords
are the switch’s passwords, regardless of which interface was used to assign
the string.

Using the Passwords

Figure 4-4. Example of the Password Window in the Web Browser Interface

The manager and operator passwords are used to control access to all switch
interfaces. Once set, you will be prompted to supply the password every time
you try to access the switch through any of its interfaces. The password you
enter determines the capability you have during that session:

�

Entering the manager password gives you full read/write capabilities

�

Entering the operator password gives you read and limited write capabil-

ities.

Using the User Names

If you also set user names in the web browser interface screen, you must
supply the correct user name for web browser interface access. If a user name
has not been set, then leave the User Name field in the password window
blank.

Port Utilization

The Port Utilization bar graphs show the network traffic on the port with a
breakdown of the packet types that have been detected (unicast packets, non­unicast packets, and error packets). The Legend identifies traffic types and
their associated colors on the bar graph:

�

% Unicast Rx & All Tx: This is all unicast traffic received and all

transmitted traffic of any type. This indicator (a blue color on many
systems) can signify either transmitted or received traffic.

�

% Non-Unicast Pkts Rx: All multicast and broadcast traffic received by

the port. This indicator (a gold color on many systems) enables you to
know “at-a-glance” the source of any non-unicast traffic that is causing
high utilization of the switch. For example, if one port is receiving heavy
broadcast or multicast traffic, all ports will become highly utilized. By
color-coding the received broadcast and multicast utilization, the bar
graph quickly and easily identifies the offending port. This makes it faster
and easier to discover the exact source of the heavy traffic because you
don’t have to examine port counter data from several ports.

�

% Error Pkts Rx: All error packets received by the port. (This indicator

is a reddish color on many systems.) Although errors received on a port
are not propagated to the rest of the network, a consistently high number
of errors on a specific port may indicate a problem on the device or
network segment connected to the indicated port.

height to reflect the level of network activity on the corresponding port,
they leave an outline to identify the maximum activity level that has been
observed on the port.

Utilization Guideline. A network utilization of 40% is considered the
maximum that a typical Ethernet-type network can experience before encoun­tering performance difficulties. If you observe utilization that is consistently
higher than 40% on any port, click on the Port Counters button to get a detailed
set of counters for the port.

To change the amount of bandwidth the Port Utilization bar graph
shows. Click on the bandwidth display contro l button in the upper left corner

of the graph. (The button shows the current scale setting, such as 40%.) In the
resulting menu, select the bandwidth scale you want the graph to show (3%,
10%, 25%, 40%, 75%, or 100%), as shown in figure

figure 4-10.

Note that when viewing activity on a gigabit port, you may want to select a
lower value (such as 3% or 10%). This is because the bandwidth utilization of
current network applications on gigabit links is typically minimal, and may
not appear on the graph if the scale is set to show high bandwidth utilization.

Port Connected – the port is enabled and is properly connected to an

active network device.

�

Port Not Connected – the port is enabled but is not connected to an

active network device. A cable may not be connected to the port, or the
device at the other end may be powered off or inoperable, or the cable or
connected device could be faulty.

�

Port Disabled – the port has been configured as disabled through the

web browser interface, the switch console, or SNMP network manage­ment.

�

Port Fault-Disabled – a fault condition has occurred on the port that

has caused it to be auto-disabled. Note that the Port Fault-Disabled
symbol will be displayed in the legend only if one or more of the ports is
in that status. See appendix B, “Monitoring and Analyzing Switch Opera­tion” for more information.

The Alert Log

The web browser interface Alert Log, shown in the lower half of the screen,
shows a list of network occurrences, or alerts, that were detected by the
switch. Typical alerts are Broadcast Storm, indicating an excessive number of
broadcasts received on a port, and Problem Cable, indicating a faulty cable. A
full list of alerts is shown in the table on

Figure 4-13. Example of the Alert Log

Each alert has the following fields of information:

�

Status – The level of severity of the event generated. Severity levels can

be Information, Normal, Warning, and Critical. If the alert is new (has not
yet been acknowledged), the New symbol is also in the Status column.

�

Alert – The specific event identification.

�

Date/Time – The date and time the event was received by the web

browser interface. This value is shown in the format: DD-MM-YY
HH:MM:SS AM/PM, for example, 16-Sep-99 7:58:44 AM.

�

Description – A short narrative statement that describes the event. For

example, Excessive CRC/Alignment errors on port: 8.

Sorting the Alert Log Entries

The alerts are sorted, by default, by the Date/Time field with the most recent
alert listed at the top of the list. The second most recent alert is displayed
below the top alert and so on. If alerts occurred at the same time, the
simultaneous alerts are sorted by order in which they appear in the MIB.

The alert field that is being used to sort the alert log is indicated by which
column heading is in bold. You can sort by any of the other columns by clicking
on the column heading. The Alert and Description columns are sorted alpha­betically, while the Status column is sorted by severity type, with more critical
severity indicators appearing above less critical indicators.

Overview

This chapter describes:

�

How switch memory manages configuration changes

�

How the CLI implements configuration changes

�

How the menu interface and web browser interface implement configu-

ration changes

�

How the switch provides OS (operating system) options through primary/

�

How to use the switch’s primary and secondary flash options, including

topics

Overview of Configuration File Management

5-2

The switch maintains two configuration files, the running-config file and the
startup-config file.

Volatile Memory

Running-Config File

(Controls switch operation. When the switch reboots,
the contents of this file are erased and replaced by the
contents of the startup-config file.)

Flash (Non-Volatile) Memory

Startup-Config File

(Preserves the most recently saved configuration
through any subsequent reboot.)

CLI configuration
changes are written to
this file. To use the CLI to
save the latest version of
this file to the startup­config file, you must
execute the write
memory command.

Menu interface configu­ration changes are simul­taneously written to both
of these files.

Figure 5-1. Conceptual Illustration of Switch Memory Operation

Overview of Configuration File Management

�

Running Config File: Exists in volatile memory and controls switch

operation. If no configuration changes have been made in the CLI since
the switch was last booted, the running-config file is identical to the
startup-config file.

�

Startup-config File: Exists in flash (non-volatile) memory and is used

to preserve the most recently-saved configuration as the “permanent”
configuration.

Rebooting the switch replaces the current running-config file with a new
running-config file that is an exact copy of the current startup-config file.

Not e Any of the following actions reboots the switch:

• Executing the boot or the reload command in the CLI

• Executing the Reboot command in the menu interface

• Pressing the Reset button on the front of the switch

• Removing, then restoring power to the switch

For more on reboots and the switch’s dual-flash images, see “Using Primary
and Secondary Flash Image Options” on page 5-12.

Switch Memory and Configuration

Options for Saving a New Configuration. Making one or more changes
to the running-config file creates a new operating configuration. Saving a new
configuration means to overwrite (replace) the current startup-config file with
the current running-config file. This means that if the switch subsequently
reboots for any reason, it will resume operation using the new configuration
instead of the configuration previously defined in the startup-config file. There
are three ways to save a new configuration:

�

In the CLI: Use the write memory command. This overwrites the current

startup-config file with the contents of the current running-config file.

�

In the menu interface: Use the Save command. This overwrites both the

running-config file and the startup-config file with the changes you have
specified in the menu interface screen.

�

In the web browser interface: Use the

���������������

button or other
appropriate button. This overwrites both the running-config file and the
startup-config file with the changes you have specified in the web browser
interface window.

Note that using the CLI instead of the menu or web browser interface gives
you the option of changing the running configuration without affecting the
startup configuration. This allows you to test the change without making it

“permanent”. When you are satisfied that the change is satisfactory, you can
make it permanent by executing the
suppose you use the following command to disable port 5:

HPswitch(config)# interface ethernet 5 disable

The above command disables port 5 in the running-config file, but not in the
startup-config file. Port 5 remains disabled only until the switch reboots. If
you want port 5 to remain disabled through the next reboot, use
to save the current running-config file to the startup-config file in flash
memory.

HPswitch(config)# write memory

If you use the CLI to make a configuration change and then change from the
CLI to the Menu interface without first using write memory to save the change

example, if you use the CLI to create VLAN 20, and then select the menu
interface, VLAN 20 is configured in the running-config file, but not in the
startup-config file. In this case you will see:

How To Use the CLI To View the Current Configuration Files. Use

show commands to view the configuration for individual features, such as port

status or Spanning Tree Protocol. However, to view either the entire startup­config file or the entire running-config file, use the following commands:

�

show config — Displays a listing of the current startup-config file.

�

show running-config — Displays a listing of the current running-config file.

�

write terminal — Displays a listing of the current running-config file.

�

show config status — Compares the startup-config file to the running-

config file and lists one of the following results:

• If the two configurations are the same you will see:
– Running configuration is the same as the startup

configuration.

• If the two configurations are different, you will see:
– Running configuration has been changed and needs

to be saved.

No t e Show config, show running-config, and write terminal commands display the

configuration settings that differ from the switch’s factory-default configura­tion.

How To Use the CLI To Reconfigure Switch Features. Use this proce­dure to permanently change the switch configuration (that is, to enter a change
in the startup-config file).

1. Use the appropriate CLI commands to reconfigure the desired switch
parameters. This updates the selected parameters in the running-config
file.

2. Use the appropriate
made the desired changes.

3. Observe the switch’s performance with the new parameter settings to
verify the effect of your changes.

4. When you are satisfied that you have the correct parameter settings, use
the write memory command to copy the changes to the startup-config file.

Syntax: write memory

For example, the default port mode setting is

auto. Suppose that your network

uses Cat 3 wiring and you want to connect the switch to another autosensing
device capable of 100 Mbps operation. Because 100 Mbps over Cat 3 wiring
can introduce transmission problems, the recommended port mode is

auto-10,

which allows the port to negotiate full- or half-duplex, but restricts speed to
10 Mbps. The following command configures port A5 to auto-10 mode in the
running-config file, allowing you to observe performance on the link without
making the mode change permanent.

HPswitch(config)# interface e a5 speed-duplex auto-10

After you are satisfied that the link is operating properly, you can save the
change to the switch’s permanent configuration (the startup-config file) by
executing the following command:

HPswitch(config)# write memory

The new mode (

auto-10) on port A5 is now saved in the startup-config file, and

the startup-config and running-config files are identical. If you subsequently
reboot the switch, the

auto-10 mode configuration on port A5 will remain

because it is included in the startup-config file.

How To Cancel Changes You Have Made to the Running-Config File.

If you use the CLI to change parameter settings in the running-config file, and
then decide that you don’t want those changes to remain, you can use either
of the following methods to remove them:

�

Manually enter the earlier values you had for the changed settings. (This

is recommended if you want to restore a small number of parameter
settings to their previous boot-up values.)

�

Update the running-config file to match the startup-config file by reboot-

ing the switch. (This is recommended if you want to restore a larger
number of parameter settings to their previous boot-up values.)

5-6

If you use the CLI to change a parameter setting, and then execute the
command without first executing the

write memory command to save the

boot

change, the switch prompts you to specify whether to save the changes in the
current running-config file. For example:

The above prompt means that one or more parameter settings in the running­config file differ from their counterparts in the startup-config file and you need
to choose which config file to retain and which to discard.

Menu: Implementing Configuration Changes

You can use the menu interface to simultaneously save and implement a subset
of switch configuration changes without having to reboot the switch. That is,
when you save a configuration change in the menu interface, you simulta­neously change both the running-config file and the startup-config file.
