Verify that no error packets have been received on the local port:
a.
Execute the
display interface
command and check for error packets.

b.
If the statistics are not zero, the following failures might occur:
−
Interface hardware failure
—To test the failure, connect the cable that is connected to
the local port to a correctly operating port (for example, Port A) with the same
configurations as the local port. If Port A forwards traffic correctly, you can determine
that the hardware of the local port fails. In this event, you must replace the local port with
a port that operates correctly.
−
Transceiver module, fiber, or twisted pair failure
—To test and resolve the failure,
replace the transceiver module, fiber, or twisted pair.
−
Inconsistent configurations
—Verify that the configurations (including speed and
duplex mode) of the peer are consistent with the local port. If they are inconsistent,
modify the configurations of the local port.
c.
If the problem persists, contact Hewlett Packard Enterprise Support.
When you contact Hewlett Packard Enterprise Support, provide the following diagnostic
information if packet loss occurs on the chip port with which the interface is associated:
# Execute the
debug port map slot 1
command in probe view to identify the chip port with
which the interface is associated.
[Sysname-probe]debug port map slot 1
