L2IFPPI_1.3.6.1.4.1.2011.5.25.42.2.1.7.12 hwMacFlappingAlarm

Description

L2IFPPI/4/MAC_FLAPPING_ALARM:OID [oid] The MAC address has flap value. (L2IfPort=[INTEGER], entPhysicalIndex=[INTEGER], BaseTrapSeverity=[INTEGER], BaseTrapProbableCause=[INTEGER], BaseTrapEventType=[INTEGER], MacAddr=[OCTET], VLANID=[INTEGER], FormerIfDescName=[OCTET], CurrentIfDescName=[OCTET], DeviceName=[OCTET])

MAC address flapping occurred.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.42.2.1.7.12 Warning equipmentAlarm(5)

Parameters

Name Meaning
oid Indicates the OID of the alarm.
L2IfPort Indicates the interface index.
entPhysicalIndex Indicates the device entity index.
BaseTrapSeverity Indicates the alarm severity.
BaseTrapProbableCause Indicates the alarm cause.
BaseTrapEventType Indicates the alarm type.
MacAddr Indicates the blocked MAC address.
VLANID Indicates the VLAN ID.
FormerIfDescName Indicates the interface that first learns the MAC address.
CurrentIfDescName Indicates the interface that later learns the MAC address.
DeviceName Indicates the device name.

Impact on the System

The switch fails to receive traffic from a user whose MAC address flaps.

Possible Causes

The MAC address learned by this interface was also learned by another interface.

Procedure

  1. Perform the following operations to remove loops:

    Check information about the two interfaces that learnt the same MAC address in the alarm. Shut down one of the two interfaces according to networking requirements and go to step 2.

  2. Check whether the alarm is generated again.

    • If so, another loop occurred. Shut down one of the two interfaces to eliminate the loop.
    • If not, no further action is required.
