from the display interface command is accumulating, you can determine that the port can
receive packets.
d. If the port is configured with STP, use the display stp brief command to verify that the port
is not in the discarding state.
e. If a port is set to the discarding state by STP, examine and modify the STP-related
configurations to resolve the problem.
As a best practice, configure the port as an edge port or disable STP on the port if it is
directly connected to a terminal.
f. If the port is assigned to an aggregation group, use the display link-aggregation
summary command to verify that the status of the port is Selected.
g. If the status of the port is Unselected, the port cannot send or receive data packets.
h. 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.
3. Verify that the port and the link medium are operating correctly:
a. Plug the link medium into another port that is operating correctly, and determine whether the
same problem occurs.
b. Examine the port.
− If the port is a copper port, directly connect the port to a PC.
− If the port is a fiber port, replace the transceiver module plugged into the port.
4. If the problem persists, contact Hewlett Packard Enterprise Support.
