DETAILED STEPS
PurposeCommand or Action
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 1
Specifies the port to be configured, and enter interface
configuration mode.
interface interface-id
Example:
Switch(config)# interface gigabitethernet2/0/1
Step 2
Sets the number of seconds that the switch remains in
the quiet state following a failed authentication
exchange with the client.
authentication timer inactivity seconds
Example:
Switch(config-if)# authentication timer inactivity
Step 3
The range is 1 to 65535 seconds; the default is 60.
30
Returns to privileged EXEC mode.end
Example:
Switch(config-if)# end
Step 4
Verifies your entries.
show authentication sessions interface interface-id
Example:
Switch# show authentication sessions interface
Step 5
gigabitethernet2/0/1
(Optional) Saves your entries in the configuration file.copy running-config startup-config
Example:
Switch# copy running-config startup-config
Step 6
Changing the Switch-to-Client Retransmission Time
The client responds to the EAP-request/identity frame from the switch with an EAP-response/identity frame.
If the switch does not receive this response, it waits a set period of time (known as the retransmission time)
and then resends the frame.
