Two IP addresses on ACS 5.1

atif — Mon, 11 Mar 2019 00:31:59 GMT

Is it possible to assign two IP addresses (prim/sec) to the ACS 5.1 appliance ?

The reason I am asking this is that there are more than 500+ devices pointing to primary ACS 4.2 server and the rest pointing to the secondary ACS.

With migration to ACS 5.1, will this be possible ?

Thanks,

Hi Atif,

it is not possible to config 2 ip add on ACS appliance. The two ethernet ports are provided only in case first port is down, you can use the second.

You can use replication option for fallback.

Thank you. It will be a small issue to make changes to all devices to now point to just one IP.

Just wondering that for a distributed environment, two IPs would have been nice (assuming there is only one appliance replacing multiple 4.x instances).
