802.1x Configuration Guidelines
These are the 802.1x authentication configuration guidelines:
• When the 802.1x protocol is enabled, ports are authenticated before any other Layer 2 feature is
enabled.
• The 802.1x protocol is supported on Layer 2 static-access ports, but it is not supported on these port
types:
–
Trunk port—If you try to enable 802.1x on a trunk port, an error message appears, and 802.1x
is not enabled. If you try to change the mode of an 802.1x-enabled port to trunk, the port mode
is not changed.

request to the client). This setting is not configurable.

the authentication server, the amount of time the switch
waits for a reply before retransmitting the response to the
