Chapter 1 Configuring Switch-Based Authentication
Configuring the Switch for Local Authentication and Authorization
To set up a Kerberos-authenticated server-client system, follow these steps:
• Configure the KDC by using Kerberos commands.
• Configure the switch to use the Kerberos protocol.
For instructions, see the “Kerberos Configuration Task List” section in the “Security Server Protocols”
chapter of the Cisco IOS Security Configuration Guide, Release 12.4.
Configuring the Switch for Local Authentication and
Authorization
You can configure AAA to operate without a server by setting the switch to implement AAA in local
mode. The switch then handles authentication and authorization. No accounting is available in this
configuration.
Beginning in privileged EXEC mode, follow these steps to configure the switch for local AAA:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
aaa new-model Enable AAA.
Step 3
aaa authentication login default local Set the login authentication to use the local username database. The
default keyword applies the local user database authentication to all
ports.
Step 4
aaa authorization exec local Configure user AAA authorization, check the local database, and allow
the user to run an EXEC shell.
Step 5
aaa authorization network local Configure user AAA authorization for all network-related service
requests.
Step 6
username name [privilege level]
{password encryption-type password}
Enter the local database, and establish a username-based authentication
system.
Repeat this command for each user.
• For name, specify the user ID as one word. Spaces and quotation
marks are not allowed.
• (Optional) For level, specify the privilege level the user has after
gaining access. The range is 0 to 15. Level 15 gives privileged EXEC
mode access. Level 0 gives user EXEC mode access.
• For encryption-type, enter 0 to specify that an unencrypted password
follows. Enter 7 to specify that a hidden password follows.
• For password, specify the password the user must enter to gain access
to the switch. The password must be from 1 to 25 characters, can
contain embedded spaces, and must be the last option specified in the
username command.
Step 7
end Return to privileged EXEC mode.
Step 8
show running-config Verify your entries.
Step 9
copy running-config startup-config (Optional) Save your entries in the configuration file.
