vlan vlan-id: Specifies a VLAN by its VLAN ID in the range of 1 to 4094. If you do not specify a VLAN, this command displays PIM snooping neighbor information for all VLANs.

vsi vsi-name: Specifies a VSI by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VSI, this command displays PIM snooping neighbor information for all VSIs.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays PIM snooping neighbor information for the MPU. (Distributed devices in standalone mode.)

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command displays PIM snooping neighbor information for the master device. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. If you do not specify a member device or PEX, this command displays PIM snooping neighbor information for the master device. (Centralized IRF devices.) (IRF 3 capable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command displays PIM snooping neighbor information for the global active MPU. (Distributed devices in IRF mode.) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. If you do not specify a card or PEX, this command displays PIM snooping neighbor information for the global active MPU. (Distributed devices in IRF mode.) (IRF 3 capable.)

verbose: Displays detailed information about PIM snooping neighbors. If you do not specify this keyword, the command displays brief information about PIM snooping neighbors.
