rep stcn
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.
rep stcn {interface interface-id | segment id-list | stp}
no rep stcn {interface | segment | stp}
Syntax Description
Command Default Transmission of STCNs to other interfaces, segments, or STP networks is disabled.
Command Modes Interface configuration
Command History
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.
Examples This example shows how to configure the REP primary edge port to send STCNs to segments 25 to 50:
Router (config)# interface gigabitethernet0/2
Router (config-if)# rep stcn segment 25-50
Router (config-if)# exit
You can verify your settings by entering the show interfaces rep detail privileged EXEC command.
Related Commands
interface interface-id Identifies a physical interface or port channel to receive STCNs.
segment id-list Identifies one REP segment or list of segments to receive STCNs. The range is
1 to 1024. You can also configure a sequence of segments (for example 3-5, 77,
100).
stp Specifies that the router send STCNs to an STP network.
