Solution
To resolve the issue:
1.
Verify that the ports at both ends are up.
2.
Examine the packet statistics of the port:
a.
(Optional.) Use the
reset counter interface
command in user view to clear the packet
statistics of the port.
This command resets all packet counters to 0, so that you can view the statistics changes
more clearly.
b.
Use the
display interface
command to verify that the number of outgoing packets is
accumulating.
c.
Verify that the number of error frames is not accumulating.
3.
Verify that the port configurations do not affect packet sending:
a.
Use the
display interface brief
command to verify that the port configurations are
correct.
The port configurations include the duplex mode, speed, port type, and VLAN
configurations of the ports at both ends of the link. If configuration errors exist, modify the
port configurations. If the port fails to send packets, use the
shutdown
command and then
the
undo shutdown
command to re-enable the port.
b.
If the port is configured with the spanning tree feature, use the
display stp brief
command to verify that the port is not in the discarding state.
If the port is set to the discarding state by the spanning tree feature, examine and modify the
spanning tree feature configurations to resolve the issue.
As a best practice, configure the port as an edge port or disable the spanning tree feature on
the port if it is directly connected to a terminal.
c.
If the port is in an aggregation group, use the
display link-aggregation summary
command to verify that the status of the port is
Selected
.
If the status of the port is
Unselected
, the port cannot send or receive data packets.
Determine the reasons why the port becomes
Unselected
, for example, the attribute
configurations of the port are different from the reference port. Modify the attribute
configurations of the port to make the port become
Selected
.
4.
Verify that the link medium connected to the port is operating correctly.
Plug the link medium into a new port that is operating correctly. If the new port cannot send
packets, replace the link medium.
5.
If the issue persists, collect diagnostic information and contact H3C Support.
To collect diagnostic information, execute the
display diagnostic-information
command to display or save running status data for multiple feature modules.
<Sysname> display diagnostic-information
Save or display diagnostic information (Y=save, N=display)? [Y/N]:Y
Incorrect port information
Symptom
The port transceiver module type cannot be correctly identified, and the diagnosis information is
incorrect. The port transceiver module is displayed as absent, or sometimes present and sometimes
absent.
