Displaying MRP Information
It shows the metro ring instance configured on the switch, including the ring ID and name (Metro Ring 2 - mrp-node1), the operational state (enabled), and the assigned role (master). It lists the associated VLAN (2), the topology status (not configured), and the timer values for hello messages (300 ms) and topology changes (600 ms). The output also details the ring interfaces, identifying each port (ethernet 2/2/2 and ethernet 2/2/3), its role in the ring (primary or secondary), the forwarding state (forwarding or blocking), and the interface type (regular). Finally, it provides counters for control traffic, including Ring Hello Packets (RHPs) sent and received, topology change (TC) events, and RBPDUs received, along with the current ring state.
