%Feb 24 15:04:44:243 2013 DeviceA LPDT/5/LPDT RECOVERED: Loopback on GigabitEthernet1/0/1
recovered.
%Feb 24 15:04:44:248 2013 DeviceA LPDT/5/LPDT RECOVERED: Loopback on GigabitEthernet1/0/2
recovered.
The output shows the following information:
•
Device A detected loops on ports GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 within a loop
detection interval.
•
Loops on ports GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 were removed.
# Use the display loopback-detection command to display the loop detection configuration and
status on devices, for example, Device A.
[DeviceA] display loopback-detection
Loop detection is enabled.
Loop detection interval is 35 second(s).
No loopback is detected.
The output shows that the device has removed the loops from GigabitEthernet 1/0/1 and
GigabitEthernet 1/0/2 according to the shutdown action.
# Display the status of GigabitEthernet 1/0/1 on devices, for example, Device A.
[DeviceA] display interface gigabitethernet 1/0/1
GigabitEthernet1/0/1 current state: DOWN (Loop detection down)
...
The output shows that GigabitEthernet 1/0/1 is already shut down by the loop detection module.
# Display the status of GigabitEthernet 1/0/2 on devices, for example, Device A.
[DeviceA] display interface gigabitethernet 1/0/2
GigabitEthernet1/0/2 current state: DOWN (Loop detection down)
...
The output shows that GigabitEthernet 1/0/2 is already shut down by the loop detection module.
