ISE- MAB - Session Uptime

[babalao]

Hello,

We have implemented MAB and dot1x with ISE and Cisco switches.

I have noticed that a lot of endpoints authenticated by MAB the "Session Uptime" resets every 30 sec. I see this with the command show auth sess int x/x detail                                                                                                                                                                   .....                                                                                                                                                                                                         Session Uptime: 11s   ---- when reaches 30 it starts over.

But with other devices this does not happen. Happens with some cameras and some phones, but with some only.

Where if possible is this configurable?  Do you know what is that value?

Thank you!

can you run debug mab all 
share debug here 
then disable debug 
the reauth timer some time is same as session timer

debug will give us hint if ISE send reauth or session timer to SW or not
