ECML/3/ECM_CHANNEL_FAULT

Message

ECML/3/ECM_CHANNEL_FAULT: Stack port [STRING] channel status is fault, port status is [STRING].

Description

A stack channel is faulty.

Parameters

Parameter Name Parameter Meaning
Stack port [STRING] Indicates a port name.
port status is [STRING] Indicates the port status.

Possible Causes

Stack probe packets are lost.

Procedure

  • Check whether there are CRC-errored packets on the stack port.

    Run the display stack channel all command to check the stack link connections and status. If the Speed field of a physical member port displays a speed value and an exclamation mark, for example, 2.5!, the port has received CRC-errored packets. Check whether the optical module or cable on the port is the correct type.

  • Check whether the physical member port sends and receives packets normally.

    Run the display interface command to check packet statistics on the physical member port. If the numbers of packets sent and received on the port do not increase, the port does not send or receive packets normally.

  • Check the CPU usage

    Run the display cpu-usage command to check the CPU usage of each process. If a process has high CPU resource, there may not be sufficient CPU usage for the stacking task. In this case, reduce the CPU usage of that process, and then check whether the stacking service recovers.
