If a member interface is Down, check the following items on the interface.
Check Item
Method
Whether the
interface was
manually shut
down
Run the
interface
interface-type interface-number
command in the
system view to enter the interface view, and then run the
display
this
command to check the interface status. If the interface was shut
down by using the
shutdown
command, run the
undo shutdown
command in the interface view.
Whether the link
fails
Replace the cable between RouterA and RouterB.
NOTE
If RouterA connects to RouterB using a twisted pair, select a new twisted
pair with a proper transmission distance according to the actual distance
between RouterA and RouterB.
Whether the
interface fails
Configure other idle interfaces as member interfaces of the Eth-
Trunk.
If the interface remains in the Down state, go to
l
If the member interface is Up, verify that each cable is correctly connected to interfaces.
If the fault persists, go to
.
Step 2
Check information about Eth-Trunk member interfaces on both ends.
Check information about member interfaces of the Eth-Trunk interface on Router A and
Router B.

Check information about member interfaces of the Eth-Trunk interface on Router B.

If the number of member interfaces of the Eth-Trunk interface on Router A differs from
the number on Router B, add the required physical interfaces to the Eth-Trunk interface.
