ISE scale question.

[MikeAoD]

Hi Team, I have an standalone ISE 2.2 using TACACS+ with 350 max. concurrent sessions and I want to confirm if the ISE could support around 1500 additional Radius sessions, right now we have a VM with all the required characteristics for an small deployment.

Likely ok as long as you don’t have an exorbitant amount of Transaction per seconds on the tacacs side

Smallest stand alone is 5k radius sessions
