Configure the WAN Network
The two WAN ports on each metro node director support dual 10 Gigabit Ethernet inter-cluster links. The WAN ports are
configured as part of the installation of a second cluster. This chapter describes the CLI contexts and procedures to change the
configuration created during installation.
Topics:
• Metro node hardware and WAN ports
• Metro over IP WAN port configuration rules
• CLI contexts
• Managing and Monitoring back-end network
• LDAP
Metro node hardware and WAN ports
In a metro node Metro over IP cluster, the director has two 10 Gigabit Ethernet (10 GbE) ports named WC-00 and WC-01.
WARNING:
Data carried on WAN ports on directors and between clusters in metro node Metro configurations is
not encrypted.
To prevent DNS attacks, the WAN ports should be routed only on secure and trusted networks.
Refer to the
Simple Support Matrix for metro node
for information about encryption devices supported in metro
node configurations.
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.
Port groups
All ports named WC-00 (in a cluster) are collectively referred to as ip-port-group-0.
All ports named WC-01 (in a cluster) are collectively referred to as ip-port-group-1.
NOTE: Port group names (ip-port-group-0 and ip-port-group-1) cannot be modified.
CLI contexts
The parent context for configuring Ethernet and WAN connections is:
/clusters/cluster-*/connectivity
The /clusters/cluster-*/connectivity context contains a sub-context for each connectivity role:
