About the Feature Descriptions
In cases where a software feature is not available in all of the switch products
covered by this guide, the text specifically indicates which device(s) offer the
feature.
Getting Started
Conventions
Conventions
This guide uses the following conventions for command syntax and displayed
information.
Command Syntax Statements
Syntax: aaa port-access authenticator < port-list >
[ control < authorized | auto | unauthorized >]
■ Vertical bars ( | ) separate alternative, mutually exclusive elements.
■ Square brackets ( [ ] ) indicate optional elements.
■ Braces ( < > ) enclose required elements.
■ Braces within square brackets ( [ < > ] ) indicate a required element
within an optional choice.
■ Boldface indicates use of a CLI command, part of a CLI command
syntax, or other displayed element in general text. For example:
“Use the copy tftp command to download the key from a TFTP server.”
■ Italics indicate variables for which you must supply a value when
executing the command. For example, in this command syntax, < port-
list > indicates that you must provide one or more port numbers:
Syntax: aaa port-access authenticator < port-list >
Command Prompts
In the default configuration, your switch displays one of the following CLI
prompts:
HP ProCurve Switch 4104#
HP ProCurve Switch 4108#
HP ProCurve Switch 2626#
HP ProCurve Switch 2650#
HP ProCurve Switch 6108#
To simplify recognition, this guide uses HPswitch to represent command
prompts for all models. For example:
HPswitch#
(You can use the hostname command to change the text in the CLI prompt.)

Port Identity Convention for Examples
Screen Simulations
Figures containing simulated screen text and command output look like this:
Figure 1-1. Example of a Figure Showing a Simulated Screen
In some cases, brief command-output sequences appear outside of a numbered figure. For example:
HPswitch(config)# ip default-gateway 18.28.152.1/24
HPswitch(config)# vlan 1 ip address 18.28.36.152/24
HPswitch(config)# vlan 1 ip igmp
Port Identity Convention for Examples
This guide describes software applicable to both chassis-based and stackable
HP ProCurve switches. Where port identities are needed in an example, this
guide uses the chassis-based port identity system, such as “A1”, “B3 - B5”, “C7”,
etc. However, unless otherwise noted, such examples apply equally to the
stackable switches, which typically use only numbers, such as “1”, “3-5”, “15”,
etc. for port identities.

Overview
Overview
This chapter describes the following:
■ Switch management interfaces
■ Advantages of using each interface type
Understanding Management Interfaces
Management interfaces enable you to reconfigure the switch and to monitor
switch status and performance. Interface types include:
■ Menu interface—a menu-driven interface offering a subset of switch
commands through the built-in VT-100/ANSI console—page 2-3
■ CLI—a command line interface offering the full set of switch commands
through the VT-100/ANSI console built into the switch—page 2-4
■ Web browser interface --a switch interface offering status information
and a subset of switch commands through a standard web browser (such
as Netscape Navigator or Microsoft Internet Explorer)—
■ HP ProCurve Manager (PCM)—a windows-based network manage-
ment solution included in-box with all manageable HP ProCurve devices.
Features include automatic device discovery, network status summary,
topology and mapping, and device management.
■ HP ProCurve Manager Plus (PCM+)—a complete windows-based
network management solution that provides both the basic features
offered with PCM, as well as more advanced management features,
including in-depth traffic analysis, group and policy management, configuration management, device software updates, and advanced VLAN
management. (HP includes a copy of PCM+ in-box for a free 30-day trial.)

Selecting a Management Interface
Advantages of Using the CLI
■ Offers out-of-band access (through the RS-232 connection) to the
switch, so network bottlenecks, crashes, lack of configured or correct IP
address, and network downtime do not slow or prevent access
■ Enables Telnet (in-band) access to the menu functionality.
■ Allows faster navigation, avoiding delays that occur with slower
display of graphical objects over a web browser interface.
■ Provides more security; configuration information and passwords are
not seen on the network.

■ Features and benefits of HP ProCurve Manager:
• Network Status Summary: Upon boot-up, a network status screen
displays high-level information on network devices, end nodes,
events, and traffic levels. From here, users can research any one of
these areas to get more details.
• Alerts and Troubleshooting: An events summary screen displays
alerts to the user and categorizes them by severity, making it easier
to track where bottlenecks and issues exist in the network. Alerts
present detailed information on the problem, even down to the specific port.
• Automatic Device Discovery: This feature is customized for fast
discovery of all HP ProCurve manageable network devices. The user
can define which IP subnets to discover.
• Topology and Mapping: This feature automatically creates a map of
discovered network devices. Maps are color-coded to reflect device
status and can be viewed at multiple levels (physical view, subnet
view, or VLAN view).
• Device Management: Many device-focused tasks can be performed
directly by the software, or the user can access web-browser and
command-line interfaces with the click of a button to manage individual devices from inside the tool.
■ Features and benefits of HP ProCurve Manager Plus:
• All of the Features of HP ProCurve Manager: Refer to the above
listing.
• In-Depth Traffic Analysis: An integrated, low-overhead traffic mon-
itor interface shows detailed information on traffic throughout the
network. Using enhanced traffic analysis protocols such as Extended
RMON and sFlow, users can monitor overall traffic levels, segments
with the highest traffic, or even the top users within a network
segment.
• Group and Policy Management: Changes in configuration are
tracked and logged, and archived configurations can be applied to one
or many devices. Configurations can be compared over time or
between two devices, with the differences highlighted for users.
• Advanced VLAN Management: A new, easy-to-use VLAN management interface allows users to create and assign VLANs across the
entire network, without having to access each network device individually.

Using the Menu Interface
Overview
Overview
This chapter describes the following:
■ Overview of the Menu Interface
■ Starting and ending a Menu session (page 3-3))
■ The Main Menu (page 3-7))
■ Screen structure and navigation (page 3-9))
■ Rebooting the switch (page 3-12))
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
• Trunk groups
■ View status, counters, and Event Log information
■ Update switch software
■ Reboot the switch
• A network monitoring port
• Stack Management
• Spanning Tree operation
• SNMP community names
• IP authorized managers
• VLANs (Virtual LANs) and
GVRP
For a detailed list of menu features, see the “Menu Features List” on page 3-14).
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.)
3-2
Starting and Ending a Menu Session
Using the Menu Interface
Note 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, see the chapter on local passwords in
the Access Security Guide for your switch.
■ 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.
■ The stack Commander, if the switch is a stack member
Note 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).

2. Press [E] (for E
dit on the Actions line).
3. Use [Tab] or the arrow keys ([<], [>], [^], or [v]) to highlight the
item or field.
4. Do one of the following:
– If the parameter has preconfigured values, either use the
Space bar to select a new option or type the first part of your
selection and the rest of the selection appears automatically.
(The help line instructs you to “Select” a value.)
– If there are no preconfigured values, type in a value (the Help
line instructs you to “Enter” a value).
5. If you want to change another parameter value, return to step 3.
6. If you are finished editing parameters in the displayed screen,
press
[Enter] to return to the Actions line and do one of the
following:
– To save and activate configuration changes, press
[S] (for the
Save action). This saves the changes in the startup
configuration and also implements the change in the
currently running configuration. (See Chapter 6, “Switch
Memory and Configuration”.)
– To exit from the screen without saving any changes that you
have made (or if you have not made changes), press
[C] (for
the Cancel action).
Note: In the menu interface, executing Save activates most
parameter changes and saves them in the startup configuration
(or flash) memory, and it is therefore not necessary to reboot the
switch after making these changes. But if an asterisk appears
next to any menu item you reconfigure, the switch will not
activate or save the change for that item until you reboot the
switch. In this case, rebooting should be done after you have
made all desired changes and then returned to the Main Menu.

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
Note 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
4-2
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 6, “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 local manager and operator password chapter 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 4-1. 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# _
4-3
Using the Command Line Interface (CLI)
Using the CLI
Caution HP strongly recommends that you configure a Manager password. If a Man-
ager 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 4-2. 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.
4-4
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
privileges, 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)#

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.
4-7
Using the Command Line Interface (CLI)
Using the CLI
For example, if you use the menu interface to configure an IP address of “X”
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.

Typing? at the Global Configuration level or the Context Configuration level
produces similar results. In a particular context level, the first block of
command in the listing are the commands that are most relevant to the current
context.
Use
[Tab] To Search for or Complete a Command Word. You can use
[Tab] to help you find CLI commands or to quickly complete the current word
in a command. To do so, type one or more consecutive characters in a
command and then press
[Tab] (with no spaces allowed). For example, at the
Global Configuration level, if you press

As mentioned above, if you type part of a command word and press
[Tab], the
CLI completes the current word (if you have typed enough of the word for the
CLI to distinguish it from other possibilities), including hyphenated extensions. For example:
HPswitch(config)# port

Pressing
[Tab] after a completed command word lists the further options for
that command.

Conventions for Command Option Displays. When you use the CLI to
list options for a particular command, you will see one or more of the following
conventions to help you interpret the command data:
■ Braces (< >) indicate a required choice.
■ Square brackets ([]) indicate optional elements.
■ Vertical bars (|) separate alternative, mutually exclusive options in a
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.

A similar action lists the Help showing additional parameter options for a
given command. The following example illustrates how to list the Help for an
interface command acting on a specific port:

Figure 4-8. 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:
HPswitch# interface help
Invalid input: interface

Using the CLI
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 configuration options include interface (port or trunk group) and VLAN
context 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
HPswitch(eth-C5-C8)#
HPswitch(eth-Trk1)#
Command executed at
configuration level for
entering port or trk1 static
trunk-group context.

Session with the Switch
You can start a web browser session in the following ways:
■ Using a standalone web browser on a network connection from a PC or
UNIX workstation:
• Directly connected to your network
• Connected through remote access to your network
■ Using a management station running HP ProCurve Manager on your
network
Using a Standalone Web Browser in a PC or UNIX Workstation
This procedure assumes that you are using a compatible web browser (see
the software Release Notes for more information) and that the switch is
configured with an IP address accessible from your PC or workstation. (For
more on assigning an IP address, refer to “IP Configuration” on
1. Ensure that the Java
information on this topic, refer to your browser’s online Help.

2. Use the web browser to access the switch. If your network includes a
Domain Name Server (DNS), your switch’s IP address may have a name
associated with it (for example, switch5308) that you can type in the
Location or Address field instead of the IP address. Using DNS names
typically improves browser performance. Contact your network administrator to enquire about DNS names associated with your HP switch.
Type the IP address (or DNS name) of the switch in the browser Location
or Address (URL) field and press

Using the HP Web Browser Interface
Using HP ProCurve Manager (PCM) or HP ProCurve Manager Plus (PCM+)
HP ProCurve Manager and HP ProCurve Manager Plus are designed for
installation on a network management workstation. For this reason, the
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 PCM and PCM+ requirements, refer to the information provided
with the software.
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 PCM or PCM+.
(For more on assigning an IP address, refer to “IP Configuration” on
8-3.)
To establish a web browser session with HP PCM or PCM+ running, do the
following on the network management station:
1. Make sure the Java
TM
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.

Tasks for Your First HP Web Browser Interface Session
Using the HP Web Browser Interface
Tasks for Your First HP Web Browser
Interface Session
The first time you access the web browser interface, there are three tasks that
you should perform:
■ Review the “First Time Install” window
■ Set Manager and Operator passwords
■ Set access to the web browser interface online help
Viewing the “First Time Install” Window
When you access the switch’s web browser interface for the first time, the
Alert log contains a “First Time Install” alert, as shown in figure 5-2. This gives
you information about first time installations, and provides an immediate
opportunity to set passwords for security and to specify a Fault Detection
policy, which determines the types of messages that will be displayed in the
Alert Log.
Double click on First Time Install in the Alert log (figure 5-1 on page 5-6). The
web browser interface then displays the “First Time Install” window, below.
Figure 5-2.First-Time Install Window
5-7
Using the HP Web Browser Interface
Tasks for Your First HP Web Browser Interface Session
This window is the launching point for the basic configuration you need to
perform to set web browser interface passwords to maintain security and
Fault Detection policy, which determines the types of messages that will be
displayed in the Alert Log.
To set web browser interface passwords, click on secure access to the device
to display the Device Passwords screen, and then go to the next page. (You
can also access the password screen by clicking on the Security tab.)
To set Fault Detection policy, click on select the fault detection configuration
in
the second bullet in the window and go to the section, “Setting Fault Detection
Policy” on
the Configuration tab, and then
page 5-23. (You can also access the password screen by clicking on
[Fault Detection] button.)
Creating Usernames and Passwords in the Browser Interface
You may want to create both a username and password to create access
security for your switch. There are two levels of access to the interface that
can be controlled by setting user names and passwords:
■ Operator. An Operator-level user name and password allows read-only
access to most of the web browser interface, but prevents access to the
Security window.
■ Manager. A Manager-level user name and password allows full read/
write access to the web browser interface.
5-8
Figure 5-3. The Device Passwords Window
Tasks for Your First HP Web Browser Interface Session
Using the HP Web Browser Interface
To set the passwords:
1. Access the Device Passwords screen by one of the following methods:
• If the Alert Log includes a “First Time Install” event entry, double
click on this event, then, in the resulting display, click on the
secure access to the device link.
• Select the Security tab.
2. Click in the appropriate box in the Device Passwords window and enter
user names and passwords. You will be required to repeat the password
strings in the confirmation boxes.
Both the user names and passwords can be up to 16 printable ASCII
characters.
3. Click on
[Apply Changes] to activate the user names and passwords.
5-9
Using the HP Web Browser Interface
Tasks for Your First HP Web Browser Interface Session
Note 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 5-4. 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.
Note that the Command Prompt and switch console interfaces use only the
password, and do not prompt you for the User Name.

Tasks for Your First HP Web Browser Interface Session
Using the HP Web Browser Interface
If You Lose a Password
If you lose the passwords, you can clear them by pressing the Clear button on
the front of the switch. This action deletes all password and user name
protection from all of the switch’s interfaces.
The Clear button is provided for your convenience, but its presence means
that if you are concerned with the security of the switch configuration and
operation, you should make sure the switch is installed in a secure location,
such as a locked wiring closet.(For more information, refer to “Front Panel
Security” in the chapter titled “Configuring Username and Password Security” in the Access Security Guide for your switch.)

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

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 control 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 5-10.
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.

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. For
more information on alerts, see
Figure 5-13.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

reported to the Alert Log based on their level of severity.
Set this policy in the Fault Detection window (figure 5-16).
Figure 5-16. The Fault Detection Window
The Fault Detection screen contains a list box for setting fault detection and
response policy. You set the sensitivity level at which a network problem
should generate an alert and send it to the Alert Log.
To provide the most information on network problems in the Alert Log, the
recommended sensitivity level for Log Network Problems is High Sensitivity. The
Fault Detection settings are:

■ High Sensitivity. This policy directs the switch to send all alerts to the
Alert Log. This setting is most effective on networks that have none or
few problems.
■ Medium Sensitivity. This policy directs the switch to send alerts related
to network problems to the Alert Log. If you want to be notified of
problems which cause a noticeable slowdown on the network, use this
setting.
■ Low Sensitivity. This policy directs the switch to send only the most
severe alerts to the Alert Log. This policy is most effective on a network
that normally has a lot of problems and you want to be informed of only
the most severe ones.
■ Never. Disables the Alert Log and transmission of alerts (traps) to the
management server (in cases where a network management tool such as
HP ProCurve Manager is in use). Use this option when you don’t want to
use the Alert Log.
The Fault Detection Window also contains three Change Control Buttons:
■ Apply Changes. This button stores the settings you have selected for all
future sessions with the web browser interface until you decide to change
them.
■ Clear Changes. This button removes your settings and returns the
settings for the list box to the level it was at in the last saved detectionsetting session.
■ Reset to Default Settings. This button reverts the policy setting to
Medium Sensitivity for Log Network Problems.

(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

■ 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.

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 Apply Changes 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
to the startup-config file, then the switch prompts you to save the change. For
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:
HPswitch(config)# vlan 20

If you type
[Y], the switch overwrites the startup-config file with the running-
config file, and your configuration change(s) will be preserved across reboots.
If you type
[N], your configuration change(s) will remain only in the running-
config file. In this case, if you do not subsequently save the running-config file,
your unsaved configuration changes will be lost if the switch reboots for any
reason.

Using the CLI To Implement Configuration Changes
Switch Memory and Configuration
Using the CLI To Implement
Configuration Changes
The CLI offers these capabilities:
■ Access to the full set of switch configuration features
■ The option of testing configuration changes before making them perma-
nent
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.
Not 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

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.)
6-6
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:
Using the CLI To Implement Configuration Changes
Disables port 1 in the running configuration, which causes port 1 to block all traffic.

Press [Y] to continue the rebooting process.
You will then see this prompt.
Do you want to save current configuration [y/n]?
Figure 6-2.Boot Prompt for an Unsaved Configuration
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.
■ If you want to update the startup-config file to match the running-config
file, press
[Y] for "yes". (This means that the changes you entered in the
running-config file will be saved in the startup-config file.)
■ If you want to discard the changes you made to the running-config file so
that it will match the startup-config file, then press
[N] for "no". (This means
that the switch will discard the changes you entered in the running-config
file and will update the running-config file to match the startup-config
file.)
Note If you use the CLI to make a change to the running-config file, you should
either use the

Configuration Changes Using the Menu Interface
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.

Using the Menu and Web Browser Interfaces To Implement Configuration Changes
Note If you reconfigure a parameter in the CLI and then go to the menu interface
without executing a write memory command, those changes are stored only in
the running configuration. If you then execute a switch reboot command in
the menu interface, the switch discards the configuration changes made while
using the CLI. To ensure that changes made while using the CLI are saved,
execute write memory in the CLI before rebooting the switch.
Rebooting from the Menu Interface
■ Terminates the current session and performs a reset of the operating
system
■ Activates any configuration changes that require a reboot
■ Resets statistical counters to zero
(Note that statistical counters can be reset to zero without rebooting the
switch. See “Displaying Port Counters” on “To Display the Port Counter
Summary Report” on page B-12.)
To Reboot the switch, use the Reboot Switch option in the Main Menu. (Note
that the Reboot Switch option is not available if you log on in Operator mode,
that is, if you enter an Operator password instead of a manager password at
the password prompt.)

Using Primary and Secondary Flash Image Options
Using Primary and Secondary Flash
Image Options
The switch features two flash memory locations for storing switch software
image files:
■ Primary Flash: The default storage for a switch software image.
■ Secondary Flash: The additional storage for either a redundant or an
alternate switch software image.
With the Primary/Secondary flash option you can test a new image in your
system without having to replace a previously existing image. You can also
use the image options for troubleshooting. For example, you can copy a
problem image into Secondary flash for later analysis and place another,
proven image in Primary flash to run your system. The switch can use only
one image at a time.
The following tasks involve primary/secondary flash options:
■ Displaying the current flash image data and determining which switch
software versions are available
■ Switch software downloads
■ Replacing and removing (erasing) a local switch software version
■ System booting
