Description

L2IFPPI/4/MFLPQUITVLANALARM:OID [oid] (VLAN=[INTEGER]) Interface [OCTET1] leaved from VLAN [OCTET2] because MAC move detected.

MAC address flapping occurred on an interface, and the interface was removed from the VLAN where MAC address flapping occurred.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.160.3.11 Warning environmentalAlarm(6)

Parameters

Name Meaning
oid Indicates ID of a MIB object.
INTEGER Indicates the VLAN ID.
OCTET1 Indicates the interface name.
OCTET2 Indicates the VLAN from which the interface is removed.

Impact on the System

Traffic of the VLAN cannot be forwarded through the interface.

Possible Causes

Cause 1:

The interfaces that form a loop belonged to the same VLAN.

Cause 2:

Cables were connected incorrectly.

Cause 3:

No loop prevention protocol such as STP was enabled.

Procedure

  1. Connect cables on the interfaces correctly and check whether the alarm persists.

    • If so, go to step 2.
    • If not, no further action is required.

  2. Check whether the two interfaces that learn the same MAC address can be added to different VLANs according to the networking.

    • If so, go to step 3.
    • If not, go to step 4.

  3. Add the two interfaces to different VLANs. Check whether the alarm persists.

    • If so, go to step 4.
    • If not, no further action is required.

  4. Enable a loop prevention protocol such as STP. Check whether the alarm persists.

    • If so, contact technical support personnel.
