Switch(config-if)# ip access-group default_acl in
Switch(config-if)# exit

Configuring RADIUS-Provided Session Timeouts

You can configure the Catalyst 4500 series switch to use a RADIUS-provided reauthentication timeout.
To configure RADIUS-provided timeouts, perform this task:
Purpose
Controls access to the specified interface.
This step is mandatory for a functioning downloaded policy.
Returns to global configuration mode.
Enables AAA.
Sets the authorization method to local. To remove the authorization
method, use the no aaa authorization network default local command.
Enables the IP device tracking table.
To disable the IP device tracking table, use the no ip device tracking
global configuration commands.
(Optional) Configures these parameters for the IP device tracking table:
•
•
(Optional) Configures the optional probe delay parameter for the IP
device tracking table:
•
Returns to privileged EXEC mode.
Displays information about the entries in the IP device tracking table.
(Optional) Saves your entries in the configuration file.
End with CNTL/Z.
