Verifying The Configuration - HP 6125XLG Configuration Manual

# Configure Ten-GigabitEthernet 1/1/5 and Ten-GigabitEthernet 1/1/6 as trunk ports, and
assign them to VLAN 100.
[DeviceB] interface ten-gigabitethernet 1/1/5
[DeviceB-Ten-GigabitEthernet1/1/5] port link-type trunk
[DeviceB-Ten-GigabitEthernet1/1/5] port trunk permit vlan 100

3. Configure Device C:
# Create VLAN 100.
<DeviceC> system-view
[DeviceC] vlan 100
[DeviceC–vlan100] quit
# Configure Ten-GigabitEthernet 1/1/5 and Ten-GigabitEthernet 1/1/6 as trunk ports, and
assign them to VLAN 100.
[DeviceC] interface ten-gigabitethernet 1/1/5
[DeviceC-Ten-GigabitEthernet1/1/5] port link-type trunk
[DeviceC-Ten-GigabitEthernet1/1/5] port trunk permit vlan 100
[DeviceC-Ten-GigabitEthernet1/1/5] quit

Verifying the configuration

After the configurations are complete, Device A detects loops on ports Ten-GigabitEthernet 1/1/5 and
Ten-GigabitEthernet 1/1/6 within a loop detection interval. Consequently, Device A automatically shuts
down the ports and generates the following log messages:
[DeviceA]
%Feb 24 15:04:29:663 2011 DeviceA LPDT/4/LOOPED:Slot=1;
Loopback exists on Ten-GigabitEthernet1/1/5.
%Feb 24 15:04:29:667 2011 DeviceA LPDT/4/LOOPED:Slot=1;
Loopback exists on Ten-GigabitEthernet1/1/6.
%Feb 24 15:04:44:243 2011 DeviceA LPDT/4/RECOVERED:Slot=1;
Loopback on Ten-GigabitEthernet1/1/5 recovered.
%Feb 24 15:04:44:248 2011 DeviceA LPDT/4/RECOVERED:Slot=1;
Loopback on Ten-GigabitEthernet1/1/6 recovered.
Use the display loopback-detection command to display the loop detection configuration and status on
Device A.
# Display the loop detection configuration and status on Device A.
[DeviceA] display loopback-detection
Loop detection is enabled.
Loop detection interval is 35 second(s).
No loopback is detected.
