Monitoring the IPv4 Bidir-PIM Running Status

Monitoring the IPv4 Bidir-PIM Running Status


During routine maintenance, you can run the following commands in any view to check the PIM running status.


  • Run the display pim claimed-route [ source-address ] command to check unicast routing information used for PIM.
  • Run the display pim bfd session [ interface interface-type interface-number | neighbor neighbor-address ] * command to check information about PIM BFD sessions.
  • Run the display pim bsr-info command to check the BSR configuration.
  • Run the display pim control-message counters [ message-type { assert | hello | join-prune | bsr | backoff | offer | pass | win } | interface interface-type interface-number ] * command to check the statistics about PIM control messages sent and received by a PIM device.
  • Run the display pim interface [ interface-type interface-number | up | down ] [ verbose ] command to check PIM information on interfaces.
  • Run the display pim neighbor [ neighbor-address | interface interface-type interface-number | verbose ] * command to check information about PIM neighbors.
  • Run either of the following commands to check PIM routing information:

    • display pim routing-table [ group-address [ mask { group-mask-length | group-mask } ] ] { rpf-interface interface-type interface-number | mode bidir } * [ outgoing-interface { include | exclude | match } { interface-type interface-number | none } | flags flag-value | fsm ] * [ outgoing-interface-number [ number ] ]
    • display pim routing-table brief [ group-address [ mask { group-mask-length | group-mask } ] | source-address [ mask { source-mask-length | source-mask } ] | incoming-interface { interface-type interface-number | register } ] *

  • Run the display pim rp-info [ group-address ] command to check information about RPs for a multicast group.
  • Run the display pim invalid-packet [ interface interface-type interface-number | message-type { assert | bsr | hello | join-prune | offer | backoff | win | pass } ] * command to check the statistics about invalid PIM control messages received by a PIM device.
  • Run the display pim df-info [ rp rp-address | interface interface-type interface-number | verbose ] * command to check information about DFs for an RP.
  • Run the display multicast global { pim sm | pim dm | bidir-pim | all } statistics command to check PIM entry restriction and statistics.
