Description

SW_SNPG/2/REFRESHFAIL:OID [OID] Failed to refresh multicast table. (Index=[INTEGER], Vlan=[OCTET])

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.44.99.1 Critical processingErrorAlarm(4)

Parameters

Name Meaning

OID

Indicates the MIB object ID of the alarm.

Index

Indicates the index of a multicast forwarding entry.

Vlan

Indicates the ID of the VLAN to which the multicast forwarding entry belongs.

Impact on the System

Some or all multicast data may fail to be forwarded.

Possible Causes

Cause 1: The system did not have sufficient memory and therefore could not allocate memory to the multicast service module.

Cause 2: The number of multicast forwarding entries in the system has reached the upper limit, and new entries could not be created.

Procedure

  • Cause 1: The system did not have sufficient memory and therefore could not allocate memory to the multicast service module.

    1. Run the display memory-usage command to check the memory usage. If the command output shows that the system memory has been used up, delete unnecessary services to release memory. If the memory has not been used up, go to step 2.

    2. Collect alarm, log, and configuration information, and contact technical support personnel.

  • Cause 2: The number of multicast forwarding entries in the system has reached the upper limit, and new entries could not be created.

    1. Run the display l2-multicast forwarding-table command to check Layer 2 multicast forwarding entries in the system. If the command output shows that the number of Layer 2 multicast forwarding entries has reached the upper limit, go to step 2. If not, go to step 3.

      NOTE:

      For the product specifications, log in to Huawei official website to download the product brochure.

    2. Manually update Layer 2 multicast forwarding entries and delete unnecessary entries.

      • If the Layer 2 multicast forwarding entries are dynamically generated through IGMP snooping, run the reset igmp-snooping group command to update the entries. This command will cause temporary interruption of multicast forwarding. Exercise caution when using this command.

      • To delete unnecessary static Layer 2 multicast forwarding entries, run the undo l2-multicast static-group command.

    3. Collect alarm, log, and configuration information, and contact technical support personnel.
