Parameters

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.

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.

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

Examples

# Display detailed information about PIM snooping neighbors for VLAN 2.

<Sysname> display pim-snooping neighbor vlan 2 slot 1 verbose

Total 2 neighbors.
