Parameters
vlan vlan-id: Displays the PIM snooping neighbor information of the specified VLAN. The vlan-id argument is in the range of 1 to 4094. If you do not specify a VLAN, this command displays the PIM snooping neighbor information of all VLANs.
slot slot-number: Displays the PIM snooping neighbor information of the card specified by its slot number. If no slot is specified, the command displays the PIM snooping neighbor information of all cards.
|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Description
Use the display pim-snooping neighbor command to display PIM snooping neighbor information.
Examples
# Display PIM snooping neighbor information about VLAN 2.
<Sysname> display pim-snooping neighbor vlan 2

Field |
Description |
Total number of neighbors |
Total number of PIM snooping neighbors. |
Neighbor |
IP address of the PIM snooping neighbor. |
Port |
Name of the port that connects to the PIM snooping neighbor. |
Expires |
Remaining time before the PIM snooping neighbor expires. Never means the PIM snooping neighbor never expires. |
Option Flags |
Possible values includes the following items: · LAN Prune Delay—Indicates that the PIM hello messages received from the neighbor carry the LAN_Prune_Delay option. · LAN Prune Delay(T)—Indicates that the PIM hello messages received from the neighbor carry the LAN_Prune_Delay option, and the join suppression function has been enabled |

Parameters
vlan vlan-id: Displays the PIM snooping routing entries of the specified VLAN. The vlan-id argument is in the range of 1 to 4094. If you do not specify a VLAN, this command displays the PIM snooping routing entries in all VLANs.
slot slot-number: Displays the PIM snooping routing entries on the card specified by its slot number. If no slot is specified, the command displays information about the PIM snooping routing entries on the main board.
|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Description
Use the display pim-snooping routing-table command to display the PIM snooping routing entries.
Examples
# Display the PIM snooping routing entries of VLAN 2.
<Sysname> display pim-snooping routing-table vlan 2
Total 1 entry(ies)
FSM Flag: NI-no info, J-join, PP-prune pending
VLAN ID: 2

NOTE: · To determine the Upstream port field of an upstream interface that is not on the main board, you must specify the slot number of the card that the interface belongs to. · To determine the Expires and FSM fields of a non-aggregate interface that is not on the main board, you must specify the slot number of the card that the interface belongs to. For aggregate interfaces, the Expires and FSM fields are displayed, whether the slot number is specified or not. |

Parameters
None
Description
Use the pim-snooping enable command to enable PIM snooping in a VLAN.
Use the undo pim-snooping enable command to disable PIM snooping in a VLAN.
By default, PIM snooping is disabled.
Before you enable PIM snooping in a VLAN, be sure to enable IGMP snooping globally and specifically in the VLAN.
PIM snooping does not work in a sub-VLAN of a multicast VLAN.
