Usage Guidelines W ith Cisc o Release 12.2(25 ) EWA, you c an use the dot1x guest-vlan supplicant command to place an
802.1X-capable host into a guest VLAN. Prior to Cisco Release 12.2(25)EWA, you could only place
non-802.1X capable hosts int o a guest VLAN.
When guest VLAN supplicant behavior is enabled, the Catalyst 4500 series switch does not maintain
EAPOL packet history. The switch allows clients that fail 802.1X authentication to access a guest
VLAN, whether or not EAPOL pack ets have been detected on the int erface.
Examples This exampl e shows how to place an 802.1X- capable supplicant ( host) into a guest VLAN:
Switch# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# dot1x guest-vlan supplicant
Switch(config)# end
Switch#
