ALM-15794223 hwEthHalfDuplex

Description

Eth half duplex. (InterfaceIndex=[hwPhysicalPortIfIndex],InterfaceName=[hwPhysicalPortName])

The interface is negotiated to work in half-duplex mode. As a result, a large number of packets are lost.

hwPhysicalPortIfIndex

Physical interface index.

hwPhysicalPortName

Physical interface name.

Impact on the System

In half-duplex mode, if bidirectional traffic is transmitted, packet loss may occur due to conflicts.

Possible Causes

Port configurations are different between the two sides (one port is set to speed force, and the other port is set to negotiation). As a result, the ports negotiate to half-duplex, and packet loss occurs, triggering a half-duplex alarm.

Procedure

  1. Check whether the rates of the interconnected interfaces at both ends are the same. If not, change them to be the same.
  2. Check whether the cable connection is correct. If yes, rectify the fault. Check whether the alarm is cleared.
    • If the alarm is cleared, go to Step 4.
    • If the alarm persists, go to Step 3.
  3. Collect alarm, log, and configuration information, and contact Huawei technical support personnel.
  4. End.
