Wireless EAP issues

Hello Community

Since ca. 2 - 3 weeks we heard about wireless troubles from our customers. Now a few days of troubleshooting later, i don't any idea why this would happen.

Our Wireless Controller is an WLC4404 with software Rev. 7.0.220.0 the controller stand in our headquarter. The Accesspoints connect over an GRE Tunnel from the branch.

Accesspoint --> Branch Router --> WAN 1Gbps GRE Tunnel --> Headquarter Router --> Core Switch --> WLC 4404

When i'm logging some Client MAC on the WLC i become the following log:

In the Log i will see that the EAP Request successfuly sended to the client but the Respond missmatch and after 3 times the controller will delete the client

Sometimes it works and somtimes not...

Through the troubleshooting i found some other interesting thing:

On the controller:

Oct 24 13:31:05.667 MET: ICMP: dst (10.2.128.142) frag. needed and DF set unreachable sent to 10.2.169.1

On the AccessPoint:

Oct 24 12:18:31.001: ICMP: dst (10.2.169.10) frag. needed and DF set unreachable rcv from 10.2.169.1

But i don't think thats the primary cause of the problem, because the MTU or MSS Size was never changed since 2010.

By the way, i don't understand why the client and the controller can't handle out the right MTU (ICMP is not blocking), maybe i'm on the wrong way regarding MTU, MSS and PMTU Discovery.

This error only happen in the Wireless interface i don't see it for other networks... and the log message are on all branch routers...

It would be great to hear somthing from somewhere who can help me to understand or to solve the problem

Many thanks for a reply!

Wireless EAP issues

Hi Kevin,

i see the client  goes to dot1x auth reqd state and then gets deleted.

i believe the radius request does not reach the radius server? can you check the radius server  if the request reaches?

is 10.2.128.142 your Radius server?

is it a consistent issue or happens once in a while? if it happens once in a while, is that the time you see the pmtu errors?

Wireless EAP issues

Hello Joseph

Thanks for reply

I've already looked at the radius server (Windows Server 2008 R2) and don't found any Event Log that seams have not todo with the problem.

A possible reason only can be that the server has to long to send an reply...

Strange is that some times the client's can auth without problems and sometimes they get an timeout message...

No 10.2.128.142, 10.2.128.144 are the ap-manager adress of the WLC and 10.2.128.241, 10.2.128.243 are the adresses for management (SSH, GUI)

The WLC can connect the radius server over an firewall, on the firewall i don't see any deny between the wlc and the radius server and additionally i don't made any changes on the radius server, firewall or wlc...

We hear about many users who have problems with the wireless so i think it happens constant, the pmtu errors happen in equal intervals (look likes an update from the controller or ap (heartbeat etc.)

I don't think there is an relation between the pmtu and eap, because i think an eap req can not contain so many data for an fragmentation, or am I wrong ?

You may want to adjust EAP

You may want to adjust EAP timers as George suggested, however when I look at the debug, first the WLC sends an Identity request (ID=1).  The Client immediatley sends an EAPOL-Start to that.  That's no big deal, it just means the supplicant has started the EAPOL exhange, therefore the WLC then sends another Identity Request (ID=2).  This would be the point that your client sends an EAPOL-Response, ie. the debug would indicate EAPOL-Packet received from client station, however it simply receives a new EAPOL-Start.

The supplicant seems to be acting problematic or you simply have something wrong "over the air" that's causing these EAPOL exchanges to not be heard on either end.

I would start by updating your device drivers and supplicant software.  For instance, if you are using Intel, make sure you are using the latest driver and version of ProSet supplicant software.  Another "test" would be to change the supplicant software you are using, such as not using Intel ProSet or whatever supplicant you have and simply connect via the native Wireless Zero Config of Windows.

Wireless EAP issues

Hi George

Thanks for your reply!

Now we restarted the WLC's and it seams the problem is solved, but we don't no why :S

I would think about your tip with adjusting the MTU size of the EAP packet... I hope it solves the problem with the to big packets...
