Scheduling Policies

The Px series application switch uses scheduling policies in load balancing to select the real server to which to forward a client request. Scheduling policies are specified as part of the server-group command. This means that any service that uses a specific server group uses the policy defined for that group.

If different policies are needed for services using the same server group, simply create another group with the same members, but with a different policy selected, using the following command:

config server-group name <string> policy [lc rr wlc wrr]
