Impact on the System

It may result in packet loss, low bandwidth usage, or even network interruption.

Possible Causes

1. The local interface or the peer interface was configured to work in half-duplex mode.

2. One of the connected interfaces worked in auto-negotiation mode whereas the other interface worked in non-automatic negotiation mode.

Procedure

Check whether the interface is expected to work in half-duplex mode.

(1) If so, go to Step 5.

(2) If not, go to Step 2.
In the interface view of the local interface and the peer interface, run the display this command to check whether the half-duplex mode is configured.

(1) If so, run the duplex full command to forcibly configure the interface to work in full-duplex mode.

(2) If not, go to Step 4.
In the interface view of the local interface and the peer interface, run the display this command to check whether one interface works in auto-negotiation mode whereas the other interface works in non-automatic negotiation mode.

(1) If so, run the negotiation auto command to configure the interface working in non-automatic negotiation mode to work in auto-negotiation mode.

(2) If not, go to Step 4.
Contact technical support personnel.
