rep block port
Examples This example shows how to configure REP VLAN load balancing on the Switch B primary edge port
(Gigabit Ethernet port 1/
0/1) and to configure Gigabit Ethernet port 1/1 of Switch A as the alternate port
to block VLANs 1 to 100. The alternate port is identified by its port ID, shown in bold in the output of
the show interface rep detail command for the Switch A port.
Switch A# show interface gigabitethernet1/1 rep detail
GigabitEthernet1/1 REP enabled
Segment-id: 2 (Segment)
PortID: 0080001647FB1780
Preferred flag: No
Operational Link Status: TWO_WAY
Current Key: 007F001647FB17800EEE
Port Role: Open
Blocked Vlan: <empty>
Admin-vlan: 1
Preempt Delay Timer: 35 sec
Load-balancing block port: none
Load-balancing block vlan: none

PDU/TLV statistics:
LSL PDU rx: 107122, tx: 192493
Switch B# config t
Switch (config)# interface gigabitethernet1/
0/1
Switch (config-if)# rep block port id 0080001647FB1780 vlan 1-100
Switch (config-if)# exit
This example shows how to configure VLAN load balancing by using a neighbor offset number and how
to verify the configuration by entering the show interfaces rep detail privileged EXEC command:
Switch# config t
Switch (config)# interface gigabitethernet1/1
Switch (config-if)# rep block port 6 vlan 1-110
Switch (config-if)# end
Switch# show interface GigabitEthernet1/1 rep detail
GigabitEthernet1/1 REP enabled
