MGMD_1.3.6.1.4.1.2011.5.25.149.3.3.8 hwMgmdGMPTotalLimit

Description

MGMD/3/GLBLIMIT:OID [oid] Membership report message is discarded because the total IGMP or MLD group membership limitation is exceeded in all instances. (GroupAddressType=[integer], SrcAddr=[binary], GrpAddr=[binary], LimitCnt=[integer])

New members failed to join the IGMP or MLD group because the total number of IGMP or MLD entries in all instances reached the limit.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.149.3.3.8	Minor	qualityOfServiceAlarm(3)

Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
GroupAddressType	Indicates the inetAddressType of group address. The value can be: 1: IPv4 address 2: IPv6 address
SrcAddr	Indicates the source address of the Report message.
GrpAddr	Indicates the group address of the Report message.
LimitCnt	Indicates the limit of IGMP or MLD entries in all instances.

Impact on the System

After the total number of entries in all instances reaches the limit, new members fail to join the IGMP or MLD group, and corresponding entries cannot be established. In this case, terminal users cannot receive the desired on-demand video programs.

Possible Causes

After the limit to the total number of IGMP or MLD entries in all instances was set on the switch, when the total number of IGMP or MLD entries reached the limit, new members failed to join the IGMP or MLD group and the corresponding trap was generated.

Global IGMP or MLD entries include the (*,G) entries, (S,G) entries, and entries in the SSM-mapping table in all instances.

Procedure

Run the display igmp all-instance group verbose and display current-configuration commands, or the display mld group verbose and display current-configuration commands to check whether the statistical number of IGMP or MLD entries in all instances is equal to or greater than the limit value that is set by the igmp global limit command or the mld global limit command.
- If so, go to Step 2.
- If not, go to Step 4.
Check the network status and judge whether more IGMP or MLD entries can be maintained on the switch of the network.
- If so, go to Step 3.
- If not, go to Step 5. This situation indicates that multicast services in the network are saturated and therefore no more IGMP or MLD entries can be added. You are advised to reduce multicast services or deploy a higher-performance device as an alternative to the current device.
Run the igmp global limit number command or the mld global limit command in the system view to increase the limit value of the IGMP or MLD entries in all instances. Then, check whether the trap persists.
- If so, go to Step 1.
- If not, go to Step 5.
Collect alarm information and configuration information, and then contact technical support personnel.
End.
