ADPVXLAN_1.3.6.1.4.1.2011.5.25.227.2.1.40 hwNotsuppDecapVxlanFragPackets

Description

ADPVXLAN/4/NOSUPPDECAPFRAG(t):OID [OID] The slot does not support to decapsulate VXLAN fragments.(Slot=[OCTET1],Vni=[INTEGER],SourceIP=[OCTET2],PeerIP=[OCTET3])

The device cannot decapsulate fragmented VXLAN packets.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.227.2.1.40	Warning	processingErrorAlarm(4)

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
OCTET1	Indicates the slot ID.
INTEGER	Indicates the VNI ID of VXLAN packets.
OCTET2	Indicates the source VTEP IP address of VXLAN packets.
OCTET3	Indicates the remote VTEP IP address of VXLAN packets.

Impact on the System

VXLAN tunnel termination fails and fragmented VXLAN packets cannot be decapsulated, which may lead to a forwarding failure of the VXLAN service traffic.

Possible Causes

The device does not support VXLAN packet decapsulation.

Procedure

Find the source VTEP based on the source IP address in the alarm and determine the access device connected to it. Set the MTU value of the interface on the access device or data source that sends the fragmented VXLAN packets to a smaller value. To change the MTU value on a Huawei S series switch, run the mtu command. Check whether the alarm is cleared.
- If so, go to step 5.
- If not, go to step 2.
Locate the forwarding devices on the VXLAN packet forwarding path based on the source and remote VTEP IP addresses in the alarm and set the MTU value of the interfaces of these devices to a larger value. To change the MTU value on a Huawei S series switch, run the mtu command. Check whether the alarm is cleared.
- If so, go to step 5.
- If not, go to step 4.
Replace the device that receives fragmented VXLAN packets on the VXLAN tunnel side with the one that supports VXLAN packet decapsulation, and then check whether the alarm is cleared.
- If so, go to step 5.
- If not, go to step 4.
Contact technical support personnel.
