rep stcn

Use the rep stcn interface configuration command on a Resilient Ethernet Protocol (REP) edge port to

configure the port to send REP segment topology change notifications (STCNs) to another interface, to

other segments, or to Spanning Tree Protocol (STP) networks. Use the no form of this command to

disable the sending of STCNs to the interface, segment, or STP network.

Syntax Description

interface interface-id Identify a physical interface or port channel to receive STCNs.

segment id-list

Transmission of STCNs to other interfaces, segments, or STP networks is disabled.

Usage Guidelines

Enter this command on a segment edge port.

You use this command to notify other portions of the Layer 2 network of topology changes that occur in

the local REP segment. This removes obsolete entries in the Layer 2 forwarding table in other parts of

the network, which allows faster network convergence.

This example shows how to configure the REP primary edge port to send STCNs to segments 25 to 50:

Switch (config)# interface gigabitethernet0/2

Switch (config-if)# rep stcn segment 25-50

Switch (config-if)# exit

You can verify your settings by entering the show interfaces rep detail privileged EXEC command.
