Indicate the mismatch type.

  • 0x01: The LAG IDs at two ends are different.
  • 0x02: The LAG aggregation types at two ends are different.
  • 0x04: The MC-LAG load-sharing modes at two ends are different.
  • 0x08: The MC-LAG revertive modes at two ends are different.

Impact on the System

Negotiation of MC-LAG configurations fails and services may be unavailable.

Possible Causes

The possible causes of the MCLAG_CFG_MISMATCH alarm are as follows:

  • Cause 1: The LAG IDs at two ends are different.
  • Cause 2: The LAG aggregation types at two ends are different.
  • Cause 3: The MC-LAG load-sharing modes at two ends are different.
  • Cause 4: The MC-LAG revertive modes at two ends are different.

Procedure

  1. Cause 1: The LAG IDs at two ends are different.

    Cause 2: The LAG aggregation types at two ends are different.

    Cause 3: The MC-LAG load-sharing modes at two ends are different.

    Cause 4: The MC-LAG revertive modes at two ends are different.

    1. Check whether the MC-LAG parameters (such as LAG ID, LAG aggregation type, LAG load-sharing mode, and LAG revertive mode) at the two ends are set to the same. If the MC-LAG parameters at the two ends are different, change them to the same. Then, check whether the alarm is cleared.
    2. If the alarm persists, contact Huawei technical support engineers for handling the alarm.
