Troubleshooting POS interfaces
Interface physically down
Symptom
The physical state of the POS interface is down.
Solution
To resolve the problem:
•
Verify that the POS interface is connected correctly to the remote port.
{
The transmit connector at one end must be connected to the receive connector at the other
end.
{
The transmit and receive connectors of the POS interface are not connected by the same
fiber. If they are connected by the same fiber, the
display interface
command displays the
"
loopback detected
" message, whether or not the loopback detection feature is enabled.
•
If the two POS interfaces are directly connected, verify that the two ends use different clock
mode settings.
•
If the problem persists, contact H3C Support.
Data link layer down
Symptom
The physical layer is up, but the data link layer is down.
