SW_SNPG_1.3.6.1.4.1.2011.5.25.44.99.1 hwCfgRefreshFailAlarm

Description

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

Layer 2 multicast forwarding entries failed to be delivered to the chip.

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 does not have sufficient memory and therefore cannot 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 cannot be created.

Procedure

  • Cause 1: The system does not have sufficient memory and therefore cannot 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 trap, 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 cannot 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 deciding to use the command.

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

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

None.

SW_SNPG_1.3.6.1.4.1.2011.5.25.44.99.2 hwMCastTableLoadAbnormalNotify

Description

SW_SNPG/4/NOTIFYTRAP:[OID] Multicast table of router was full.

The number of Layer 2 multicast forwarding entries has reached the maximum number allowed by the system.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.44.99.2 Warning equipmentAlarm(5)

Parameters

Name Meaning

OID

Indicates the MIB object ID of the alarm.

Impact on the System

New multicast forwarding entries cannot be configured or learned on the switch.

Possible Causes

The total number of Layer 2 multicast forwarding entries exceeds 90% of the upper limit.

Procedure

  1. Run the display igmp-snooping port-info command to view forwarding entries of all multicast groups, and then check whether unnecessary static multicast entries exist.

    • If so, go to step 2.

    • If not, go to step 4.

  2. Run the undo l2-multicast static-group group-address x.x.x.x command to delete unnecessary multicast entries and check whether the alarm hwMCastTableLoadAbnormalResume is generated.

    • If so, go to step 4.

    • If not, go to step 3.

  3. Collect trap, log, and configuration information, and contact technical support personnel.
  4. End.

SW_SNPG_1.3.6.1.4.1.2011.5.25.44.99.3 hwMCastTableLoadAbnormalResume

Description

SW_SNPG/4/NOTIFYTRAP:[OID] Multicast table of router was normal.

The number of Layer 2 multicast forwarding entries has dropped below the recovery threshold.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.44.99.3

Warning

equipmentAlarm(5)

Parameters

Name Meaning

OID

Indicates the MIB object ID of the alarm.

Impact on the System

None.

Possible Causes

Cause 1:

After the number of Layer 2 multicast forwarding entries exceeded 90% of the upper limit, some entries were manually deleted. The number of Layer 2 multicast forwarding entries then dropped below 80% of the upper limit.

Cause 2:

After the number of Layer 2 multicast forwarding entries exceeded 90% of the upper limit, some entries were aged out or some group members left multicast groups. The number of Layer 2 multicast forwarding entries then dropped below 80% of the upper limit.

Procedure

  1. This trap is informational only, and no action is required.

SW_SNPG_1.3.6.1.4.1.2011.5.25.44.99.16 hwL2mcCacVsiCountExceed

Description

SW_SNPG/4/VSICNTEXCEED:OID [OID] Exceed the count limit on multicast groups. (VsiName=[STRING], ConfiguredValue=[INTEGER], CurrentMulticastGroup=[IPADDR])

Layer 2 multicast CAC detects that the number of multicast groups in a VSI has exceeded the configured limit.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.44.99.16 Warning equipmentAlarm(5)

Parameters

Name Meaning

OID

Indicates the MIB object ID of the alarm.

VsiName

Indicates a VSI name.

ConfiguredValue

Indicates the configured limit on the number of multicast groups.

CurrentMulticastGroup

Indicates a multicast group address.

Impact on the System

Multicast data cannot be forwarded to new multicast groups and users cannot join new multicast groups, but this is a result of normal configuration.

Possible Causes

Users in the VSI attempt to join new multicast groups after the number of multicast groups in the VSI reaches or exceeds the configured limit.

Procedure

  1. Run the display l2-multicast limit configuration vsi [ vsi-name ] command to check whether the limit on the number of multicast groups configured for the VSI is too small.

    • If so, go to step 2.

    • If not, go to step 3.

  2. Increase the limit on the number of multicast groups in the VSI to an appropriate value based on application requirements, and then check whether the alarm persists.

    • If so, go to step 3.

    • If not, go to step 4.

  3. Collect trap, log, and configuration information, and contact technical support personnel.
  4. End.

Related Information
