HP A5120 EI Configuration Manual page 57

Neighbor aged time : 11
Interface GigabitEthernet1/0/50
DLDP port state : advertisement
DLDP link state : up
The neighbor number of the port is 1.
Neighbor mac address : 0023-8956-3600
Neighbor port index : 60
Neighbor state : two way
Neighbor aged time : 12
The output shows that both GigabitEthernet 1/0/49 and GigabitEthernet 1/0/50 are in Advertisement
state, which means both links are bidirectional.

#Jan 18 18:10:38:481
1.3.6.1.4.1.25506.2.43.2.1.1 : DLDP detects a unidirectional link in port 17825792.
%Jan 18 18:10:38:481 2010 DeviceA DLDP/3/DLDP_UNIDIRECTION_MANUAL: -Slot=1; DLDP detects
a unidirectional link on port GigabitEthernet1/0/49. The transceiver has malfunction in
the Tx direction or cross-connected links exist between the local
neighbor. The shutdown mode is MANUAL. The port needs to be shut down by the user.

1.3.6.1.4.1.25506.2.43.2.1.1 : DLDP detects a unidirectional link in port 17825793.
%Jan 18 18:10:38:618 2010 DeviceA DLDP/3/DLDP_UNIDIRECTION_MANUAL: -Slot=1; DLDP detects
a unidirectional link on port GigabitEthernet1/0/50. The transceiver has malfunction in
the Tx direction or cross-connected links exist between the local
neighbor. The shutdown mode is MANUAL. The port needs to be shut down by the user.
The output shows that DLDP has detected a unidirectional link on both GigabitEthernet 1/0/49 and
GigabitEthernet 1/0/50, and is asking you to shut down the faulty ports manually.
After you shut down GigabitEthernet 1/0/49 and GigabitEthernet 1/0/50, the following log information
is displayed:
