Metro over IP WAN port configuration rules

Metro over IP WAN ports must conform to the following rules:

• The two WAN ports on a director should be on different physical networks, and must be on different subnets so that port WC-00 (ip-port-group 0) cannot see port WC-01 (ip-port-group 1) on any director.
• All port WC-00s in the cluster (one from each director) must be in the same subnet and connected to the same LAN. Ports in the same subnet are usually connected to the same Ethernet switch.
• All port WC-01s must be in one subnet, which cannot be the same subnet used for ports WC-00.
• The management port subnet cannot be the same as either of the subnet used for the WAN ports.
