Configuring Local Authentication and Authorization

How to Configure Local Authentication and Authorization

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.


Note

To secure the switch for HTTP access by using AAA methods, you must configure the switch with the ip http authentication aaa global configuration command. Configuring AAA authentication does not secure the switch for HTTP access by using AAA methods.

Follow these steps to configure AAA to operate without a server by setting the switch to implement AAA in local mode:

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. aaa new-model
  4. aaa authentication login default local
  5. aaa authorization exec local
  6. aaa authorization network local
  7. username name [privilege level] {password encryption-type password}
  8. end
  9. show running-config
  10. copy running-config startup-config

DETAILED STEPS

  Command or Action Purpose

Step 1

enable

Example:


Switch> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

Example:


Switch# configure terminal

Enters global configuration mode.

Step 3

aaa new-model

Example:


Switch(config)# aaa new-model

Enables AAA.

Step 4

aaa authentication login default local

Example:


Switch(config)# aaa authentication login default local

Sets the login authentication to use the local username database. The default keyword applies the local user database authentication to all ports.

Step 5

aaa authorization exec local

Example:


Switch(config)# aaa authorization exec local

Configures user AAA authorization, check the local database, and allow the user to run an EXEC shell.

Step 6

aaa authorization network local

Example:


Switch(config)# aaa authorization network local

Configures user AAA authorization for all network-related service requests.

Step 7

username name [privilege level] {password encryption-type password}

Example:


Switch(config)# username your_user_name privilege 1 password 7 secret567

Enters the local database, and establishes 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 8

end

Example:


Switch(config)# end

Returns to privileged EXEC mode.

Step 9

show running-config

Example:


Switch# show running-config

Verifies your entries.

Step 10

copy running-config startup-config

Example:


Switch# copy running-config startup-config

(Optional) Saves your entries in the configuration file.

Monitoring Local Authentication and Authorization

To display Local Authentication and Authorization configuration, use the show running-config privileged EXEC command.
