Usage Guidelines With Cisco Release 12.2(25) EWA, you can 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 into 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 packets have been detected on the interface.
Examples This example 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#
