ISE 1.4: HA for PSNs

[abhijith891]

Hi all,

I am planning to deploy HA for PSNs. So I would like to know what are the pre-requisites for it: like do they need to be on same subnet? Or is it okay if they are on the same location but different subnets? Is it feasible if they happen to be on different locations? 

Regards.

Abhijit

Before doing anything with ISE 1.4, please upgrade your deployment to a current release. The currently recommended ones are 2.2 Patch 9 or ISE 2.4 Patch 1.

Supported deployment modes for PSNs in HA include all of the variations you mentioned.

To get an extensive look at all of the scale and HA options for ISE, please refer to the following Cisco Live presentation:
