Hierarchy Level


Define one of the two interface ports for Ethernet ring protection, the other being defined by the west-interface statement at the same hierarchy level. The interface must use the control channel's logical interface name. The control channel is a dedicated VLAN channel for the ring port.

EX Series switches do not use the node-id statement--the node ID is automatically configured on the switches using the MAC address.


Always configure this port first, before configuring the west-interface statement.


The Node ID is not configurable on EX Series switches. The node ID is automatically configured using the MAC address.

The remaining statements are explained separately. See CLI Explorer.
