I know of w few customer using UDT where NAC is deployed with no issues. How are you planning your deployment, in-band or out-of-band? Sounds like you're going with out-of-band.
"Also, is UDT able to use switch port mac notification or link up/down traps?" Not currently, but this is something the PM team is investigating for a future release.
Thanks for the response.
We are L2 OOB (Virtual Gateway). I was just curious because with all the automated VLAN switching that NAC does it seems that there would be a good chance of confusing UDT depending on when it polls.
