Description

MRM/3/CACOIFTOTAL:OID [oid] PIM received join from interface is discarded due to the OIF total limitation. (SrcAddr=[ipaddr], GrpAddr=[ipaddr], IfIndex=[integer], OifTotalCurCnt=[integer], StatBandWidth=[string], IfName=[string], InstanceName=[string])

PIM entries failed to be created due to the CAC limit configuration on the outbound interface.

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

SrcAddr

Indicates the source address.

GrpAddr

Indicates the group address.

IfIndex

Indicates the interface index.

OifTotalCurCnt

Indicates the number of PIM entries.

StatBandWidth

Indicates the statistics of bandwidth.

IfName

Indicates the name of the interface.

InstanceName

Indicates the instance name.

Impact on the System

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

Possible Causes

The global CAC limit was configured on the outgoing interface, and the interface received the PIM Join message. This trap is generated when either the sum of the PIM entries to be created and the existing entries or the total bandwidth of these entries 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.

By default, the bandwidth of each entry is 2 Mbit/s.

Procedure

  1. Run the display multicast [ vpn-instance vpn-instance-name ] limit out-interface interface-type interface-number command to check whether the value of Entries equals the value of Used-Entries and whether available bandwidth, namely, the difference between Bandwidth and Used-Bandwidth, is smaller than the bandwidth of an entry.

    • 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 out { max-entry limit | bandwidth traffic-rate } * command to increase the total entry limit or bandwidth limit of the outgoing interface. 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.
