Edit 802.1x Authentication (Switch Ports)
This window allows you to enable and configure 802.1x authentication
parameters.
If a message is displayed indicating that the port is operati ng in trunk mode
instead of the 802.1x authentication parameters, then the switch cannot have
802.1x authentication enabled.
If the 802.1x authentication parameters appear but are disabled, then one of the
following is true:
AAA has not been enabled.
To enable AAA, go to Configure > Additional Tasks > AAA.
AAA has been enabled, but an 802.1x authentication pol icy has not been
configured.
To configure an 802.1x authentication policy, go to Configure > Additional
Tasks > AAA > Authentication Policies > 802.1x.

Enable 802.1x Authentication

Check Enable 802.1x Authentication to enable 802.1x authentication on this
switch port.

Host Mode

Choose Single or Multiple. Single mode allows only one authenticated client to
have access. Multiple mode allows for any number of clients to have access once
a single client has been authenticated.
Note Ports on Cisco 87x routers can be set only to multiple host mode. Single mode is
disabled for these routers.
