Monitoring the IPv4 PIM Running Status

Monitoring the IPv4 PIM Running Status

Context

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

Procedure

  • Run the display pim [ vpn-instance vpn-instance-name | all-instance ] claimed-route [ source-address ] command to check unicast routes used by PIM.
  • Run the display pim [ vpn-instance vpn-instance-name | all-instance ] bfd session [ interface interface-type interface-number | neighbor neighbor-address ] * command to check the PIM BFD session.
  • Run the display pim [ vpn-instance vpn-instance-name | all-instance ] bsr-info command in any view to check information about the BSR in the PIM-SM domain.
  • Run the following commands to check the number of sent and received PIM control packets.

    • display pim [ vpn-instance vpn-instance-name | all-instance ] control-message counters message-type { probe | register | register-stop | crp }

    • display pim [ vpn-instance vpn-instance-name | all-instance ] control-message counters [ message-type { assert | graft | graft-ack | hello | join-prune | state-refresh | bsr } | interface interface-type interface-number ] *

  • Run the display pim [ vpn-instance vpn-instance-name | all-instance ] interface [ interface-type interface-number | up | down ] [ verbose ] command in any view to check PIM information on an interface.
  • Run the display pim [ vpn-instance vpn-instance-name | all-instance ] neighbor [ neighbor-address | interface interface-type interface-number | verbose ] * command to check information about the PIM neighbor.
  • Run the following commands to check the PIM routing table.

    • display pim [ vpn-instance vpn-instance-name | all-instance ] routing-table [ group-address [ mask { group-mask-length | group-mask } ] | source-address [ mask { source-mask-length | source-mask } ] | incoming-interface { interface-type interface-number | register } | outgoing-interface { include | exclude | match } { interface-type interface-number | register | none } | mode { dm | sm | ssm } | flags flag-value | fsm ] * [ outgoing-interface-number [ number ] ]

    • display pim routing-table [ group-address [ mask { group-mask-length | group-mask } ] | source-address [ mask { source-mask-length | source-mask } ] | incoming-interface { interface-type interface-number | register } | outgoing-interface { include | exclude | match } { interface-type interface-number | vpn-instance vpn-instance-name | register | none } | mode { dm | sm | ssm } | flags flag-value | fsm ] * [ outgoing-interface-number [ number ] ]

    • display pim [ vpn-instance vpn-instance-name | all-instance ] 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 [ vpn-instance vpn-instance-name | all-instance ] rp-info [ group-address ] command to check information about RPs of the multicast group.
  • Run the display pim [ vpn-instance vpn-instance-name | all-instance ] invalid-packet [ interface interface-type interface-number | message-type { assert | bsr | hello | join-prune | graft | graft-ack | state-refresh } ] * command to check the statistics about the invalid PIM packets received by the device.
