Introduction and Applicable Switches
Introduction and Applicable Switches
This guide describes how to use HP’s switch security features to protect
access to your HP ProCurveProCurve switch. This guide is intended for these
switch models:
■ HP ProCurve Switch 4100GL Series (4104GL, 4108GL)
■ HP ProCurve Switch 2800 Series (2824, 2848)
■ HP ProCurve Switch 2600 Series (2626, 2650)
■ HP ProCurve Switch 6108
The Product Documentation CD-ROM shipped with the switch includes this
guide. You can also download the latest version from the HP ProCurve
website. (Refer to
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 devices offer the
feature.
“Getting Documentation From the Web” on page 1-9.)

Overview of Access Security Features
Getting Started
Overview of Access Security Features
■ Local Manager and Operator Passwords (page 2-1): Control
access and privileges for the CLI, menu, and web browser interfaces.
■ TACACS+ Authentication (page 4-1): Uses an authentication appli-
cation on a server to allow or deny access to a switch.
■ RADIUS Authentication and Accounting (page 5-1): Like
TACACS+, uses an authentication application on a central server to
allow or deny access to the switch. RADIUS also provides accounting
services for sending data about user activity and system events to a
RADIUS server.
■ Secure Shell (SSH) Authentication (page 6-1): Provides
encrypted paths for remote access to switch management functions.
■ Secure Socket Layer (SSL) (page 7-1): Provides remote web access
to the switch via encrypted authentication paths between the switch
and management station clients capable of SSL/TLS operation.
■ Port-Based Access Control (802.1X) (page 8-1): On point-to-point
connections, enables the switch to allow or deny traffic between a
port and an 802.1X-aware device (supplicant) attempting to access
the switch. Also enables the switch to operate as a supplicant for
connections to other 802.1X-aware switches.
■ Port Security (page 9-1): Enables a switch port to maintain a unique
list of MAC addresses defining which specific devices are allowed to
access the network through that port. Also enables a port to detect,
prevent, and log access attempts by unauthorized devices.
■ Traffic/Security Filters (page 10-1 ): Source-Port filtering enhances
in-band security by enabling outbound destination ports on the switch
to forward or drop traffic from designated source ports (within the
same VLAN).
■ Authorized IP Managers (page 11-1): Allows access to the switch
by a networked device having an IP address previously configured in
the switch as "authorized".
HP recommends that you use local passwords together with your switch’s
other security features to provide a more comprehensive security fabric than
if you use only local passwords. For an overview, refer to
Table 1-1.

There are two security areas to protect: access to the switch management
features and access to the network through the switch. The preceeding table
shows the type of protection each switch security feature offers.
General Switch Traffic Security Guideline
Getting Started
General Switch Traffic Security
Guideline
Where the switch is running multiple security options, it implements network
traffic security based on the OSI (Open Systems Interconnection model)
precedence of the individual options, from the lowest to the highest. The
following list shows the order in which the switch implements configured
security features on traffic moving through a given port.
1. Disabled/Enabled physical port
2. MAC lockout (Applies to all ports on the switch.)
3. MAC lockdown
4. Port security
5. Authorized IP Managers
6. Application features at higher levels in the OSI model, such as SSH.
(The above list does not address the mutually exclusive relationship that
exists among some security features.)

Command Syntax Conventions
Command Syntax Conventions
This guide uses the following conventions for command syntax and displays.
Syntax: aaa port-access authenticator < port-list >
■ Vertical bars ( | ) separate alternative, mutually exclusive elements.
■ Square brackets ( [ ] ) indicate optional elements.
■ Braces ( < > ) enclose required elements.
■ Braces within square brackets ( [ < > ] ) indicate a required element
■ Boldface indicates use of a CLI command, part of a CLI command
■ Italics indicate variables for which you must supply a value when
[ control < authorized | auto | unauthorized >]
within an optional choice.
syntax, or other displayed element in general text. For example:
“Use the copy tftp command to download the key from a TFTP server.”
executing the command. For example, in this command syntax, you
must provide one or more port numbers:
Syntax: aaa port-access authenticator < port-list >
Simulating Display Output
Command Prompts
In the default configuration, your switch’s CLI prompt includes the switch
model number, and appears similar to the following examples:
HP ProCurve Switch 4108#
HP ProCurve Switch 2650#
HP ProCurve Switch 6108#
To simplify recognition, this guide uses HPswitch to represent command
prompts for all models. That is:
HPswitch#
(You can use the hostname command to change the text in the CLI prompt.)
Commands or command output positioned to simulate displays of switch
information in a computer screen are printed in a monospace font, as shown
above.
1-6
Port Identity Convention for Examples
Getting Started
Screen Simulations
Figures containing simulated screen text and command output appear similar
to this:
Figure 1-1.Example of a Figure Showing a Simulated Screen
In some cases, brief command-output sequences appear without figure identification. For example:
HPswitch(config)# clear public-key
HPswitch(config)# show ip client-public-key
show_client_public_key: cannot stat keyfile
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.

Console access includes both the menu interface and the CLI. There are two
levels of console access: Manager and Operator. For security, you can set a
password pair (username and password) on each of these levels.
Note- Usernames are optional. Also, in the menu interface, you can configure
passwords, but not usernames. To configure usernames, use the CLI or the
web browser interface.
Level Actions Permitted
Manager: Access to all console interface areas.
This is the default level. That is, if a Manager password has not been set prior
to starting the current console session, then anyone having access to the
console can access any area of the console interface.
Operator:- Access to the Status and Counters menu, the Event Log, and the CLI*, but no
Configuration capabilities.
On the Operator level, the configuration menus, Download OS, and Reboot
Switch options in the Main Menu are not available.
*Allows use of the ping, link-test, show, menu, exit, and logout commands, plus the enable
command if you can provide the Manager password.
2-2
Configuring Username and Password Security
Overview
To configure password security:
1. Set a Manager password pair (and an Operator password pair, if applicable
for your system).
2. Exit from the current console session. A Manager password pair will now
be needed for full access to the console.
If you do steps 1 and 2, above, then the next time a console session is started
for either the menu interface or the CLI, a prompt appears for a password.
Assuming you have protected both the Manager and Operator levels, the level
of access to the console interface will be determined by which password is
entered in response to the prompt.
If you set a Manager password, you may also want to configure the
Inactivity Time parameter. (Refer to the Management and Configuration
Guide for your switch.) This causes the console session to end after the
specified period of inactivity, thus giving you added security against unauthorized console access.
Note- The manager and operator passwords and (optional) usernames control
access to the menu interface, CLI, and web browser interface.
If you configure only a Manager password (with no Operator password), and
in a later session the Manager password is not entered correctly in response
to a prompt from the switch, then the switch does not allow management
access for that session.
If the switch has a password for both the Manager and Operator levels, and
neither is entered correctly in response to the switch’s password prompt, then
the switch does not allow management access for that session.
Passwords are case-sensitive.
Caution- If the switch has neither a Manager nor an Operator password, anyone
having access to the switch through either Telnet, the serial port, or the web
browser interface can access the switch with full manager privileges. Also,
if you configure only an Operator password, entering the Operator password enables full manager privileges.

b. Type a password of up to 16 ASCII characters with no spaces and
press
[Enter]. (Remember that passwords are case-sensitive.)
c. When prompted with Enter new password again, retype the new pass-
word and press
After you configure a password, if you subsequently start a new console
session, you will be prompted to enter the password. (If you use the CLI or
web browser interface to configure an optional username, the switch will
prompt you for the username, and then the password.)
[Enter].
Configuring Username and Password Security
Configuring Local Password Security
To Delete Password Protection (Including Recovery from a Lost Password): This procedure deletes all usernames (if configured) and pass-
words (Manager and Operator).
If you have physical access to the switch, press and hold the Clear button (on
the front of the switch) for a minimum of one second to clear all password
protection, then enter new passwords as described earlier in this chapter.
If you do not have physical access to the switch, you will need Manager-Level
access:
1. Enter the console at the Manager level.
2. Go to the Set Passwords screen as described above.
3. Select Delete Password Protection. You will then see the following prompt:
Continue Deletion of password protection? No
4. Press the Space bar to select Ye s, then press
5. Press
[Enter] to clear the Password Protection message.
[Enter].
To Recover from a Lost Manager Password: If you cannot start a console session at the Manager level because of a lost Manager password, you can clear the password by getting physical access to the switch and pressing and holding the Clear button for a minimum of one second. This action deletes all passwords and usernames (Manager and Operator) used by both the console and the web browser interface.

To Remove Password Protection. Removing password protection means
to eliminate password security. This command prompts you to verify that you
want to remove one or both passwords, then clears the indicated password(s).
(This command also clears the username associated with a password you are
removing.) For example, to remove the Operator password (and username, if
assigned) from the switch, you would do the following:
• Password entries appear
as asterisks.
• You must type the
password entry twice.
Press [Y] (for yes) and press [Enter].
Figure 2-3. Removing a Password and Associated Username from the Switch
The effect of executing the command in figure 2-3 is to remove password
protection from the Operator level. (This means that anyone who can access
the switch console can gain Operator access without having to enter a username or password.)
