web authentication timeout problem

mukka — Sun, 04 Jul 2021 05:41:51 GMT

We have one SSID using web-auth with ISE.

On WLC we configured idle timeout fot 2400 seconds and on wlan>advanced with 65535 seconds for session timeout. But we are having continuos deauthentication in about 10 minutes.

When we check WLC, our mac-address is deleted after about each 10 minutes

How Can I solved this issue?

Deauth can be caused by interference or even an issue with the client device. What devices are being affected? Is it everywhere or certain areas? What code and wlc an ap model do you have?

If I am connected on wlan and disable radio during 10 minutes (or go out Wi-Fi coverage area), when I enable the radio (or come back for Wi-Fi zone) I need reauthenticate

My customer would like to remain the connection during idle timeout (40 minutes).
Notebooks has this issue.

I have tested this in the past and I have never had to log back on as long as I was still under the idle timeout. I'm testing it right now and so far with the card disabled 1300 seconds and still in the RUN state.

Thanks,

You know what you should do is create a test wlan that has webauth on the wlc. Have one of your devices join that ssid and then disable the adapter. See if the issue might be with the ISE or with the WLC.

Well just to give you an update, i have my pc wlan card disabled for 3 hours and the client is still in the run state. So I would try to determine if the WLC or ISE is causing you the issue.

Well didn't know you we're doing that also.. Since your doing PSK, that changes everything. You would have to go in the CLI of the wlc and change the key timeout.

The ability to configure the WPA-Handshake timeout through the WLCs was integrated in software release 4.2 and later. You do not need this option in earlier WLC software versions.

These commands can be used to change the WPA Handshake timeout:

config advanced eap eapol-key-timeout config advanced eap ?

eapol-key-timeout

Configures EAPOL-Key Timeout in seconds.

eapol-key-retries

Configures EAPOL-Key Max Retries.

identity-request-timeout

Configures EAP-Identity-Request Timeout in seconds.

identity-request-retries

Configures EAP-Identity-Request Max Retries.

key-index

Configure the key index used for

dynamic WEP(802.1x) unicast key (PTK).

max-login-ignore-identity-response

Configure to ignore the same username count

reaching max in the EAP identity response

request-timeout

Configures EAP-Request Timeout in seconds.

request-retries

Configures EAP-Request Max Retries.
