Cisco ISE not support IOT device

[oumodom]

Dear Cisco lover, 

We would like to seek your support on case not functional IoT device when we perform Closed Mode on cisco ise such the MAC addresss can't be learn on switch port. 
Once we configure on switch with Low Impact mode, the  IoT device is able to perform without any interruption. 

It would be great if someone experienced this case and share the fix solution. 

Cisco ISE v3.1
Thank you,

Hi @Aref Alsouqi  could you please share the workable software on switch, since we are running the latest software already.

I am a Cisco ISE lover. Also some IOT network stacks are very poorly implemented. Make sure the firmware is up to date. If that doesn't work you may need to exclude that particular port from authentication.

It depends, I would look at the open caveat/bugs of the release you are running and see if there is anything reported in there.
