Configuring Monitor Link

Configuration Prerequisites

Before assigning a port to a monitor link group, make sure the port is not the member port of any
aggregation group.

Configuration Procedure

Follow these steps to configure monitor link:
Enter system view
Create a monitor link group and enter
monitor link group view
Configure the
uplink for the
monitor link group
Configure the
downlink for the
monitor link group
A port can be assigned to only one monitor link group.
You are recommended to configure uplink ports prior to downlink ports, thus avoiding undesired
down/up state changes on the downlink ports.
Monitor Link Configuration Example
Network requirements
GigabitEthernet1/0/1 and GigabitEthernet1/0/2 of a device are up. Configure GigabitEthernet1/0/2 to
change its up/down state as GigabitEthernet1/0/1.
