authentication disable-aging

Disables aging of MAC sessions at the interface level.
Syntax
authentication disable-aging { permitted-mac-only | denied-mac-only }
no authentication disable-aging { permitted-mac-only | denied-mac-only }
Command Default

Aging of MAC sessions is not disabled.

Parameters
permitted-mac-only

Prevents permitted (authenticated and restricted) sessions from being aged out and ages denied sessions.

denied-mac-only

Prevents denied sessions from being aged out, but ages out permitted sessions.

Modes

Interface configuration mode

Usage Guidelines

Use this command to disable the aging of MAC sessions. Use the authentication disable-aging command at the interface level and the disable-aging command in the authentication configuration mode. Entered at the interface level, this command overrides the command entered at the authentication global level. However, the global configuration to disable aging of MAC sessions will still be applicable to other ports that don't have configuration at the interface level.

The no form of the command does not disable aging.

Examples

The following example disables aging for permitted MAC addresses. 

device(config)# authentication
device(config-authen)# interface ethernet 1/1/1
device(config-if-e1000-1/1/1)# authentication disable-aging permitted-mac-only
