NAC randomly fails mac-locked end systems reauthentication

[et1000]

Hello,

I’m facing a problem since I upgraded XMC and Extreme Control to 8.4.4.26. Sometimes, random mac-locked end systems are blocked because the periodic reauthentication fails with the following message:

The locked end system is connected to switch: xxx.xxx.xxx.xxx, port: null instead of: 1:4

If I force reauth, it’s working again. If I wait until the next automatic reauth, it’s working again to. But it can fail again in the future.

The switches are X440-G2 with firmware 22.6.1.4.

Is it a known bug?

Thanks!

Emile

Hello,

We have a known issue with port information being removed from end systems in 8.4. It should be resolved in 8.5.

Thanks
