Chapter Cisco MWR 2941 Router Command Reference, Release 15.1(3)MR

rep block port

Use the rep block port interface configuration command on the REP primary edge port to configure

Resilient Ethernet Protocol (REP) VLAN load balancing. Use the no form of this command to return to

the default configuration.

rep block port {id port-id | neighbor_offset | preferred} vlan {vlan-list | all}

no rep block port {id port-id | neighbor_offset | preferred}

Syntax Description

Defaults The default behavior after you enter the rep preempt segment privileged EXEC command (for manual

preemption) is to block all VLANs at the primary edge port. This behavior remains until you configure

the rep block port command.

If the primary edge port cannot determine which port is to be the alternate port, the default action is no

preemption and no VLAN load balancing.

Command Modes Interface configuration

Command History

Usage Guidelines You must enter this command on the REP primary edge port.

id port-id Identify the VLAN blocking alternate port by entering the unique port ID that is

automatically generated when REP is enabled. The REP port ID is a 16-character

hexadecimal value. You can view the port ID for an interface by entering the show

interface interface-id rep detail command.

neighbor_offset Identify the VLAN blocking alternate port by entering the offset number of a

neighbor. The range is –256 to +256; a value of 0 is invalid. The primary edge port

has an offset number of 1; positive numbers above 1 identify downstream

neighbors of the primary edge port. Negative numbers identify the secondary edge

port (offset number -1) and its downstream neighbors.

preferred Identify the VLAN blocking alternate port as the segment port on which you

entered the rep segment segment-id preferred interface configuration command.

Note Entering the preferred keyword does not ensure that the preferred port is

the alternate port; it gives it preference over other similar ports.

vlan Identify the VLANs to be blocked.

vlan-list Enter a VLAN ID from 1 to 4094 or a range or sequence of VLANs (such as 1-3,

22, 41-44) of VLANs to be blocked.

all Enter to block all VLANs.
