User Guidelines
This command configures the Ethernet Ring Protection Link (RPL) and role.
The administrator must ensure that only one RPL Owner is configured per
ring and that the RPL port role is configured as RPL Neighbor on the
connecting link of the adjacent switch.
• RPL Owner: The owner is responsible for the RPL's blocking and
forwarding states. This ensures that no loops are formed in the ring. There
can be only one RPL owner in a ring.
• RPL Neighbor: The Ethernet ring node connected to the RPL owner node.
It is responsible for blocking its end of the RPL when no failures are
present. This configuration is optional.
Example
This example configures a closed ring node for interface Te1/0/1 and Te1/0/2.
A single instance is created and associated with ERP profile1. The profile sets
the hold-off timer to 500 milliseconds. Interface Te1/0/2 is configured in the
Owner role. Interface Te1/0/2 connects to an adjacent switch port Te1/0/1.
Traffic is blocked on these two ports under normal conditions.
