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

  Total number of neighbors: 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

 

display pim-snooping routing-table

Syntax

Default level

1: Monitor level

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

    Total 1 entry(ies)

    (172.10.10.1, 225.1.1.1)

      Upstream neighbor: 20.1.1.1

        Total number of downstream ports: 2

          1: GE3/1/3

             Expires: 00:03:01, FSM: J

          2: GE3/1/4

      Upstream neighbor: 10.1.1.1

        Total number of downstream ports: 1

          1: GE3/1/5

 

 

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.

Default level

2: System level

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.
