Solution - H3C S5150-EI Series Troubleshooting Manual

Solution

To resolve the problem:
1. Verify that no error packets have been received on the local port:
a. Execute the display interface command and check for error packets.
<Sysname>display interface Ten-GigabitEthernet1/0/25
Ten-GigabitEthernet1/0/25 current state: UP
Line protocol state: UP
IP Packet Frame Type: PKTFMT_ETHNT_2, Hardware Address: aa11-2233-4496
......
Last 300 seconds input:
Last 300 seconds output:
Input (total):

Input:
Output (total): 1440 packets, 475200 bytes
Output (normal): 1440 packets, - bytes
Output: 0 output errors, - underruns, - buffer failures
b. If the statistics are not zero, the following failures might occur:
− Interface hardware failure—To test such a failure, connect the cable that is connected
− Transceiver module, fiber, or twisted pair failure—To test and resolve such a failure,
− Inconsistent configurations—Verify that the configurations (including speed and
c. If the problem persists, contact H3C Support.
When you contact H3C 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

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 correctly operating port.
replace the transceiver module, fiber, or twisted pair with a good one.

modify the configurations of the local port.
