By default, the management servers are assigned the same priority when configured for failover and load balancing. If you want to change the default priority after installation, you can do so by using the Symantec Endpoint Protection Manager console. You can only configure load balancing when a site includes more than one management server.
Load balancing occurs between the servers that are assigned to priority 1 in a management server list. If more than one server is assigned to priority 1, the clients randomly choose one of the servers and establish communication with it. If all priority 1 servers fail, clients connect with the server assigned to priority 2.
To provide both load balancing and roaming:
Enable DNS and put a domain name as the only entry in a custom management server list.
Enable the Symantec Endpoint Protection location awareness feature and use a custom management server list for each location. Create at least one location for each of your sites.
Use a hardware device that provides failover or load balancing. Many of these devices also offer a setup for roaming.
