Monitoring PIM
The PIM MIB is supported only on platform e
FTOS fully supports the PIM MIB as specified in RFC 5060 with some exceptions.
• The following tables are not supported:
• pimBidirDFElectionTable
• pimAnycastRPSetTable
• The OIDs related to InvalidRegisterMsgs reflect the last received invalid register message. Similarly,
the OIDs related to InvalidJoinPruneMsgs reflect the last received invalid Join or Prune message.
• OIDs which refer to any timer show the time that the timer started; it is 0 otherwise.
PIM-SM and IGMP Snooping: Usage Notes
PIM-SM is supported with IGMP snooping. The example in PIM-SM snooping: show ip pim snooping
neighbor shows the egress ports used for outgoing multicast traffic when you enable different
combinations of PIM-SM DR flooding and IGMP snooping flooding on a switch/router.
When you enable PIM-SM and IGMP snooping at the same time:
• The IGMP report is forwarded on the port that connects to the PIM DR.
• The port that connects to the PIM DR port and ports on which IGMP queries are received are chosen as
IGMP mrouter ports. It is recommended that you configure the both the IGMP querier and the PIM DR
in the same router to avoid unnecessary flooding.
• It is recommended that you do not enable IGMP snooping on a PIM-SM snooping-enabled VLAN
interface unless until it is necessary for VLAN operation.
2 Apply the ACL to an interface on which there
might be a source for a group specified in the ACL.
This command maps the incoming interface to the
(*,G) entry so that the entry can be programmed
into hardware.
