MRM_1. hwIpMcastGlobalChannelLimit


MRM/3/CACGLBCHN:OID [oid] PIM received join belongs to channel is discarded due to the global limitation based on this channel. (SrcAddr=[ipaddr], GrpAddr=[ipaddr], ChnName=[string], GlbCurCnt=[integer], InstanceName=[string])

PIM entries cannot be created because the channel-based global CAC limit was configured.

Name Meaning


Indicates the MIB object ID of the alarm.


Indicates the source address.


Indicates the group address.


Indicates the channel name.


Indicates the number of PIM entries.


Indicates the instance name.

Impact on the System

PIM entries cannot be created, which will affect the transfer of multicast data.

Possible Causes

The maximum number of channel-based entries of the instance was configuredin the channel-name view. This trap is generated when the number of channel-based entries of the instance exceeded the limit.

For groups in the ASM group address range, the same G, (*,G) entry and all (S,G) entries are counted as one entry. For groups in the SSM group address range, one (S,G) entry is counted as one entry.


  1. Run the display multicast [ vpn-instance vpn-instance-name ] limit channel channel-name global command to check whether the value of Entries equals the value of Used-Entries.

    • If so, go to Step 2.

    • If not, go to Step 4.

  2. Check the network status and judge whether more multicast data can be contained in 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 entries can be added. It is recommended to reduce multicast services or deploy a higher-performance device as an alternative to the current device.

  3. Run the multicast limit limit [ threshold threshold ] command in the channel-name view to increase the entry limit of the specific channel in the current instance. Then, check whether the trap persists.

    • If so, go to Step 1.

    • If not, go to Step 5.

  4. Collect alarm information and configuration information, and then contact technical support personnel.
  5. End.
