Conguring Timeouts
If the supplicant or the authentication server is unresponsive, the authenticator terminates the authentication process after 30 seconds by
default. You can congure the amount of time the authenticator waits for a response.
To terminate the authentication process, use the following commands:
• Terminate the authentication process due to an unresponsive supplicant.
INTERFACE mode
dot1x supplicant-timeout seconds
The range is from 1 to 300.
The default is 30.
• Terminate the authentication process due to an unresponsive authentication server.
INTERFACE mode
dot1x server-timeout seconds
The range is from 1 to 300.
