Solution

To resolve the issue:
1. Verify that the speed and duplex mode of the local port match the speed and duplex mode of
the peer port:
The 1/10GBASE-T ports on the device can operate only at 10 Gbps or 1 Gbps and cannot
operate at 10 Mbps or 100 Mbps.
a. 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.
b. If they do not match, use the speed command and the duplex command to set the rate and
duplex mode for the port.
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 to verify that the local port is operating correctly.
