802.1X Port Authentication
– 848 –
COMMAND USAGE
This command sets the timeout for EAP-request frames other than EAP-
request/identity frames. If dot1x authentication is enabled on a port, the
switch will initiate authentication when the port link state comes up. It will
send an EAP-request/identity frame to the client to request its identity,
followed by one or more requests for authentication information. It may
also send other EAP-request frames to the client during an active
connection as required for reauthentication.
EXAMPLE
Console(config)#interface eth 1/2
Console(config-if)#dot1x timeout supp-timeout 300
Console(config-if)#
dot1x timeout
tx-period
This command sets the time that an interface on the switch waits during an
