• Member ports of Layer 2 aggregation groups
• S-channel interfaces and S-channel aggregate interfaces
Follow these guidelines when you configure monitor link group member interfaces:
• To avoid undesired down/up state changes on the downlink interfaces, configure uplink
interfaces before you configure downlink interfaces.
• To avoid interrupting Monitor Link operation, do not assign the aggregate interface and member
ports of an aggregation group to the same monitor link group.
• An interface can be assigned to only one monitor link group.
In monitor link group view
To configure member interfaces for a monitor link group in monitor link group view:
Step Command Remarks
1. Enter system view.

N/A
3. Configure member interfaces
for the monitor link group.

3. Configure the current interface
as a member of a monitor link
group.

By default, the interface is not a
monitor link group member.

3. Configure the switchover
delay for the downlink
interfaces in the monitor link
group.
downlink up-delay
delay
By default, the switchover delay
for the downlink interfaces is 0
seconds. The downlink
interfaces come up as soon as
an uplink interface comes up.
