Protocol version of IEEE 802.1x

Unanswered Question
Dec 31st, 2007


I ask question of dot1x's protocol version.

I want to configure version 1 of IEEE802.1x.

But, defaut version is 2 from IOS 12.2(25)SEE.

Could you tell me, how to configure for version 1 fo IEEE 802.1x.

(I use WS-C2950G-48TC-L)


I have this problem too.

I don't think you can ;-). But I'm interested in why you need to.

Our network is design for version 1 of IEEE 802.1X.

We have some Catalyst switch.



These are running IOS at 12.2(25)SEC.

(This protocol version of IEEE 802.1X is 1)

I can't anthenticate when WS-C2960G-48TC-L is running IOS 12.2(40)SE.

(This protocol viersion of IEEE 802.1X is 2)

I can't authenticate when WS-C3560G-48TS-S is running IOS at 12.2(40)SE.

But I can authenticate when WS-C3560G-48TS-S is running IOS at 12.2(25)SEC.

(These are same configuration)

I think this problem is version 2 of IEEE 802.1X.

(My configuration for version 1 of IEEE 802.1X)

I want to resolve this problem.

Best regards.

Yes, I think the protocol number changed as of 12.2(25)SEE. I hope the protocol version is not the problem, since the 2 should be completely interchangeable ;-).

I think there's something else amiss here.

Config, problem description, AAA failure, etc. might help.
