Solution

To resolve the problem:
1. Verify that the speed and duplex mode of the local port match the speed and duplex mode of
the peer port:
a. Execute the display interface command to verify that the port is up.
b. If the port is down, use the undo shutdown command to bring up the port.
c. Execute the display interface brief command to examine whether the speed and duplex
mode of the port match the speed and duplex mode of the peer port.
d. If they do not match, use the speed command and the duplex command to set the speed
and duplex mode for the port.
NOTE:
The speed and duplex mode of network management ports cannot be configured in the current
software version.
2. Replace the network cable with a new one to verify that the network cable is in good condition.
3. Replace the local port with a new one (on an interface module of the same type, if possible) to
verify that the local port is operating correctly.
4. Replace the peer port with a new one (on an interface module of the same type, if possible) to
verify that the peer port is operating correctly.
5. If the problem persists, contact Hewlett Packard Enterprise Support.
