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.

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 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.

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

Usage guidelines

You must enable the IGMP snooping feature and enable IGMP snooping for a VLAN or VSI before you enable PIM snooping for the VLAN or VSI.

PIM snooping does not take effect on sub-VLANs of a multicast VLAN.

Examples

# Enable the IGMP snooping feature, and then enable IGMP snooping and PIM snooping for VLAN 2.

<Sysname> system-view

[Sysname] igmp-snooping
