I am trying to enable 802.1x on one of

the switchports of the Cisco Catalyst


C2960#sh run | i radius

aaa authentication login test group radius local

aaa authentication dot1x default group radius

radius-server host auth-port 1812 acct-port 1813

radius-server source-ports 1645-1646

radius-server key 123456

C2960#sh run | i dot

aaa authentication dot1x default group radius

dot1x system-auth-control

dot1x guest-vlan supplicant

dot1x critical eapol

C2960#conf t

Enter configuration commands, one per line. End with CNTL/Z.

C2960(config)#int g0/14

C2960(config-if)#dot1x ?

% Unrecognized command


As you can see, I can not enable 802.1x

at the interface level. The code is am running is 12.2.25SEE4:

Switch Ports Model SW Version SW Image

------ ----- ----- ---------- ----------

* 1 24 WS-C2960G-24TC-L 12.2(25)SEE4 C2960-LANBASEK9-M

System image file is "flash:c2960-lanbasek9-mz.122-25.SEE4.bin"

According to Cisco, this image supports

802.1x. Why can't enable it at the

interface level?

Can someone help me out? Thanks.

Before typing dot1x under interface try

C2960(config)#int g0/14

C2960(config-if)# switchport mode access

C2960(config-if)# dot1x ?

This works only if switchport is access port. So configure switchport mode access.

You must input "swithport mode access" first, then you can input 802.1x cmd.
