MID_L2BPTNL_1.3.6.1.4.1.2011.5.25.42.2.1.7.15 hwL2ProtocolTunnelDropThresholdRaising

Description

MID_L2BPTNL/1/L2BPTNL_DROP_THRESHOLD_ALARM:OID [oid] The number of the protocol transmit on the port reach the drop threshold. (PortName=[OCTET], ProtocolName=[OCTET], Dropthreshold=[INTEGER])

The number of Layer 2 protocol packets transmitted on the interface enabled with Layer 2 protocol transparent transmission reached the threshold.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.42.2.1.7.15	Critical	communicationsAlarm (2)

Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
PortName	Name of the interface that is enabled with Layer 2 protocol transparent transmission
ProtocolName	Name of the protocol whose packets are transparently transmitted
Dropthreshold	Threshold for discarding Layer 2 protocol packets

Impact on the System

Services will not be affected.

Possible Causes

The interface enabled with Layer 2 protocol transparent transmission was configured with the threshold for discarding Layer 2 protocol packets, and the number of Layer 2 protocol packets that were transparently transmitted on the interface reached the threshold.

Procedure

Run the display l2protocol-tunnel statistics command to check the number of discarded packets and check whether insecure attack packets cause excessive transparently transmitted packets.
- If there are attack packets, configure security functions to block these packets.
- If there are no attack packets, no handling is required. If the threshold for discarding Layer 2 protocol packets on an interface enabled with Layer 2 protocol transparent transmission needs to be reconfigured, run the l2protocol-tunnel drop-threshold command.
