Configuring 802.1x Authentication
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
authentication as fallback method:
Switch# configure terminal
Switch(config)# interface gigabitethernet 1/0/1
Switch(config)# authentication order dot1x webauth
Configuring Open1x
Beginning in privileged EXEC mode:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Specify the port to be configured, and enter interface
configuration mode.
Step 3
authentication order dot1x | mab {webauth} (Optional) Set the order of authentication methods used on a port.
Step 4
authentication priority dot1x | mab
{webauth}
(Optional) Add an authentication method to the port-priority list.
Step 5
show authentication (Optional) Verify your entries.
Step 6
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose

bidirectional.
Step 4
authentication fallback name (Optional) Configure a port to use web authentication as a
fallback method for clients that do not support 802.1x
authentication.
Step 5
authentication host-mode [multi-auth |
multi-domain | multi-host | single-host]
(Optional) Set the authorization manager mode on a port.
Step 6
authentication open (Optional) Enable or disable open access on a port.
Step 7
authentication order dot1x | mab {webauth} (Optional) Set the order of authentication methods used on a port.
Step 8
authentication periodic (Optional) Enable or disable reauthentication on a port.
Step 9
authentication port-control {auto |
force-authorized | force-un authorized}
