rep block port
To configure a REP VLAN load balancing on the REP primary edge port, use the rep block port command
in interface configuration mode. To return to the default configuration with VLAN 1 as the administrative
VLAN, use the
no form of this command.
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
Specifies the VLAN blocking alternate port by entering the unique port ID, which is
automatically generated when REP is enabled. The REP port ID is a 16-character
hexadecimal value. You can display the port ID for an interface by entering the
show
interface interface-id rep detail
command in privileged EXEC mode.
id port-id
Identifies the VLAN blocking alternate port by entering the offset number of a
neighbor. The range is from -256 to +256; a value of 0 is invalid. neighbor-offset
Selects the regular segment port previously identified as the preferred alternate port
for VLAN load balancing.
preferred
Identifies the VLANs to be blocked. vlan
VLAN ID or range of VLAN IDs to be displayed. Enter a VLAN ID from 1 to 4094
or a range or sequence of VLANs (such as 1-3, 22, 41-44) to be blocked. vlan-list
Blocks all the VLANs. all
Command Default
The default behavior after you enter the rep preempt segment command in privileged EXEC (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.
