3. Troubleshooting Functional Failures in Operation

2 Execute the show oadp command to check
the port information displayed.
If the information on the port to which the neighboring system is connected
appears in "Enabled Port," go to No. 3.
If the information on the port to which the neighboring system is connected does
not appear in "Enabled Port," the port is not covered by the OADP function. Enable
the OADP function for the port. Note that the OADP function is disabled for the
ports included in a channel group. Enable the OADP function for the channel
group.
3 Execute the show oadp statistics
command to check for the statistics on the
port to which the neighboring system is
connected.
If the Tx count has been incremented while the Rx has not, also check No. 1
through 3 on the neighboring system. If the Tx count also has been incremented on
the neighboring system, check the connection, since the systems may be
incorrectly connected.
If the Discard/ERR count has been incremented, check the connection between the
systems.
Otherwise, go to No. 4.
4 Execute the show interfaces
command to check the status of the port to
which the neighboring system is connected.
If the port status is "active up," go to No. 5.
Otherwise, see "3.4 Network Interface Communication Failure."
5 Execute the show vlan command to check
the status of the VLAN containing the port to
which the neighboring system is connected.
If "Status" is "Up," go to No. 6.
If "Status" is "Disabled," it is not covered by the OADP function. Enable the
VLAN state.
Otherwise, see "3.5 Layer 2 Network Communication Failure."
6 Execute the show oadp command to check
neighboring system information on the port
to which neighboring system is connected.
If no information is displayed, check No. 1 through 6 on the neighboring system.
If the neighboring system information is not displayed on the neighboring system,
connection between systems may be incorrect. Therefore, check the connection.
OADP control frames may have been discarded by filtering or QoS control. See
"3.23.1 Checking Filtering/QoS Setting Information" to check for it.
