To use automatic registration, prepare the appliance for registration with the SCC by entering the IP address or DNS-registered hostname of the SCC when you run the configuration wizard on the appliance. Riverbed recommends that you set up your DNS servers to resolve riverbedcmc to the primary interface IP address of your SCC. If you configure your DHCP servers to forward the correct DNS settings, any appliance added into the network and powered on should automatically register with the SCC.

Alternatively, you can use the cmc enable and cmc hostname commands. If you do not change the default hostname, it remains riverbedcmc.
