Configuring REP Interfaces
For REP operation, you need to enable it on each segment interface and identify the segment ID. This
step is required and must be done before other REP configuration. You must also configure a primary
and secondary edge port on each segment. All other steps are optional.
To enable and configure REP on an interface, perform this task:
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(config)# interface interface-id
Specifies the interface, and enter interface configuration mode. The
interface can be a physical Layer 2 interface or a port channel
(logical interface). The port-channel range is 1 to 48.
Step 3
Switch(config-if)# switchport mode trunk
or,
switchport mode private-vlan trunk
promiscuous
Configures the Layer 2 interface as a Layer 2 trunk port.
Configures the Layer 2 interface as a PVLAN promiscuous trunk
port.
For information on command options for PVLAN promiscuous trunk
ports, refer to “Configuring a Layer 2 Interface as a Promiscuous
PVLAN Trunk Port” on page 21.
Note With REP, only the switchport mode private-vlan trunk
promiscuous command is supported; other PVLAN trunk
related configurations are not supported.
