3. Troubleshooting Functional Failures During Operation
3.17 Communication failures in the neighboring device management
functionality
3.17.1 Neighboring device information cannot be obtained by the LLDP
functionality
If neighboring device information cannot be obtained correctly by using the LLDP functionality,
isolate the cause of the problem according to the failure analysis method described in the following
table.
Table 3-73: Failure analysis method when the LLDP functionality is used

functionality.
2 Execute the
show lldp
check the port information.
3 Execute the
show lldp statistics
command and check the statistics for
the port to which the neighboring device
is connected.
4 Execute the
show lldp
check the port status in the information
for the port to which the neighboring
device is connected.
5 Execute the
show lldp
check the number of neighboring device
information items on the port to which
the neighboring device is connected.
3.17.2 Neighboring device information cannot be obtained by the OADP
functionality
If neighboring device information cannot be obtained correctly by using the OADP functionality,
isolate the cause of the problem according to the failure analysis method described in the following
table.
