MRM/3/CACGLBTOTAL:OID [oid] Pim received join is discarded due to the global total limitation. (SrcAddr=[ipaddr], GrpAddr=[ipaddr], TotalCurCnt=[integer], InstanceName=[string])

PIM entries cannot be created because the global CAC limit of an instance was configured.

Impact on the System

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

Possible Causes

The global CAC limit of entries was configured in the multicast-channel view of the public network or VPN instance. This trap is generated when the number of all PIM 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 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 4. 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. Collect alarm information and configuration information, and then contact technical support personnel.
  4. End.
