Figure 12 Troubleshooting incorrect port information
Solution
1.
Execute the
display transceiver interface
command to view basic information of the
transceiver modules and identify the incorrect information of the transceiver module.
2.
See the installation guide for the device to identify whether the transceiver module is supported.
If the transceiver module is not supported, replace it with an H3C transceiver module supported
by the device.
3.
Identify whether the I2C of the port is normal.
a.
Identify whether the transceiver module type or diagnosis information of another port of the
same PHY (typically, a neighboring port) is incorrect. If the transceiver module type or
diagnosis information of another port is also incorrect, the I2C might be abnormal. Contact
H3C Support.
b.
If another port does not have this problem, replace the transceiver module. If the problem is
resolved after replacement, contact H3C Support.
4.
Execute commands in the following table to collect information and contact H3C Support.
