Use the command set mgc list on a branch gateway while adding a PE-enabled Avaya Solutions Platform S8300 as a primary controller or as an alternate controller. The primary controller or gatekeeper is the first gateway controller on the list.

For example, an NIC card with IP address 10.1.1.1 is chosen for the PE interface during configuration. The set mgc list command is:

set mgc list 10.1.1.1, <alt_ip-address_1>, <alt ip-address 2>
