ALM-303046977 An Interface Receives a Packet with an Insecure MAC Address

Description

L2IFPPI/4/PORTACTIONTRAP:OID [OID] Interface ([INTEGER1]/[INTEGER2]) [OCTET] receive insecure mac-address, and the port status is : [INTEGER]. (1:restrict;2:protect;3:shutdown)

An interface receives a packet with an insecure MAC address.

Attribute

Alarm ID	Alarm Severity	Alarm Type
303046977	Warning	Quality of service alarm

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
[INTEGER1]/[INTEGER2]	Indicates the interface index.
OCTET	Indicates the interface name.
INTEGER3	Indicates the interface status.

Impact on the System

Traffic transmission on an interface is affected.

Possible Causes

Cause 1:

The number of MAC address entries reaches the threshold.

Procedure

Check the port status.
- If the port is in restrict state, go to step 2.
- If the port is in shutdown state, go to step 3.
Run the port-security max-mac-num max-number command to increase the maximum number of secure dynamic MAC addresses that can be learned by an interface. Then check whether the traffic transmission is normal.
- If yes, go to step 5.
- If not, go to step 4.
Run the undo shutdown command. Then check whether the traffic transmission is normal.
- If yes, go to step 5.
- If not, go to step 4.
Contact technical support personnel.
