Configuring 802.1x Authentication
This example shows how to globally enable VLAN ID-based MAC authentication on a switch:

Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# mab request forma
t attribute 32 vlan access-vlan
Switch(config-if)# exit
Configuring Flexible Authentication Ordering
Beginning in privileged EXEC mode, follow these steps:
This example shows how to configure a port attempt 802.1x authentication first, followed by web
aut
hentication as fallback method:
Switch# configure terminal
Switch(config)# interface gigabit
ethernet 1/0/1
Switch(config)# authentication or
der dot1x webauth
Configuring Open1x
Beginning in privileged EXEC mode:
