example.
Step 6 Verify the configuration.
Simulate a fault, and then check whether the status of the blocked interface changes from blocked
to forwarding.
Run the shutdown command on GE 1/0/1 of LSW2 to simulate an interface fault.
Run the display sep interface command on LSW3 to check whether the status of GE1/0/1 in
SEP segment 1 changes from blocked to forwarding.
[LSW3] display sep interface gigabitethernet 1/0/1
SEP segment 1
----------------------------------------------------------------
Interface Port Role Neighbor Status Port Status
----------------------------------------------------------------
GE1/0/1 common up forwarding
SEP segment 2
----------------------------------------------------------------
Interface Port Role Neighbor Status Port Status
----------------------------------------------------------------
GE1/0/1 common up forwarding
The preceding command output shows that the status of GE 1/0/1 changes from blocked to
forwarding and the forwarding path change in SEP segment 1 does not affect the forwarding
path in SEP segment 2.
