How many session does the switch support for Multi-Auth mode?

[Hiep Nguyen]

Hi team,

We have customer deploying ISE with multi-auth mode on Cat 3650 switch. My question is how many authentication session supported on single port of the switch? I can not find any document mention about that limit number. Thank you.

In general there is no limitation as to how many data devices can be authenticated.

"When multi-auth is configured, a single authenticated phone is allowed in the voice domain (as with MDA) but an unlimited number of data devices can be authenticated in the data domain".

Be sure to check the image your running is within the compatibility requirements.

Hi Danny, is there a hardware limitation on a single port though? thanks

Hi Hiep, did you ever try this out? I see the answer is 'unlimited' but surely there must be a restriction as to how much the port hardware can handle
