DLDP unidirectional-shutdown mode: Auto
DLDP delaydown-timer value: 1s
Number of enabled ports: 2
Interface Ten-GigabitEthernet1/0/1
DLDP port state: Bidirectional
Number of the port’s neighbors: 1
Neighbor MAC address: 0023-8956-3600
Neighbor port index: 1
Neighbor state: Confirmed
Neighbor aged time: 11s
Interface Ten-GigabitEthernet1/0/2
DLDP port state: Bidirectional
Number of the port’s neighbors: 1
Neighbor MAC address: 0023-8956-3600
Neighbor port index: 2
Neighbor state: Confirmed
Neighbor aged time: 12s
The output shows that both Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 are in
Bidirectional state, which means both links are bidirectional.
# Enable the monitoring of logs on the current terminal on Device A, and set the lowest level of the
logs that can be output to the current terminal to 6.
[DeviceA] quit
<DeviceA> terminal monitor
<DeviceA> terminal logging level 6
The following log information is displayed on Device A:
<DeviceA>%Jul 11 17:40:31:089 2013 DeviceA IFNET/3/PHY_UPDOWN:
Ten-GigabitEthernet1/0/1 link status is DOWN.
%Jul 11 17:40:31:091 2013 DeviceA IFNET/5/LINK_UPDOWN: Line protocol on the interface
Ten-GigabitEthernet1/0/1 is DOWN.
%Jul 11 17:40:31:677 2013 DeviceA IFNET/3/PHY_UPDOWN: Ten-GigabitEthernet1/0/2 link
status is DOWN.
%Jul 11 17:40:31:678 2013 DeviceA IFNET/5/LINK_UPDOWN: Line protocol on the interface
Ten-GigabitEthernet1/0/2 is DOWN.
%Jul 11 17:40:38:544 2013 DeviceA IFNET/3/PHY_UPDOWN: Ten-GigabitEthernet1/0/1 link
status is UP.
%Jul 11 17:40:38:836 2013 DeviceA IFNET/3/PHY_UPDOWN: Ten-GigabitEthernet1/0/2 link
status is UP.
The output shows that the port status of both Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet
1/0/2 is down and then up, but the link status of them is always down.
