ISE Device Administration NAS limit

[leciscokid]

Is there any sizing guidance available for number of maximum NAS or concurrent TACACS Authorizations into an ISE Deployment ?

I have (2) clients who wish to deploy stand alone ISE deployments specifically to replace ACS TACACS deployments.

ACS was licensed for Large Deployment when going over 500 NAS and there's obviously nothing of that sort in ISE when it comes to device admin. There also isn't a stated limit, that I can find.

The client in question is a small SP with 1200+ NAS calling in  TACACS+ AuthN and Command AuthZ.

Does anyone have any doc pointing to sizing or Max NAS configuration in 2.x+ ?

Thanks in advance,

BD

Hi,

Please see the Appendices of ACS to ISE Migration that discusses the deployment limits between ACS and ISE.
