we have hundreds of cisco devices on our network. we are currently deploying TACACS authentication/authorization on the network.
The devices need to be grouped, and NARs need to be assigned to different groups of people.
The network is very dynamic so cisco switches are being added/removed every day.
My question is is there a way to import network devices to ACS and place them automatically in the right NDG?
What do you think is the best way to keep ACS up to date with the latest changes on the network in my case?
