display pim-snooping ipv6 neighbor

Syntax

In standalone mode:

display pim-snooping ipv6 neighbor [ vlan vlan-id ] [ slot slot-number ] [ | { begin | exclude | include } regular-expression ]

In IRF mode:

display pim-snooping ipv6 neighbor [ vlan vlan-id ] [ chassis chassis-number slot slot-number ] [ | { begin | exclude | include } regular-expression ]

View

Any view

Default level

1: Monitor level

Parameters

vlan vlan-id: Specifies a VLAN. The value range for the vlan-id argument is 1 to 4094. If no VLAN is specified, this command displays the IPv6 PIM snooping neighbor information in all VLANs.

slot slot-number: Displays the IPv6 PIM snooping neighbor information of the card specified by its slot number. If no slot is specified, the command displays the IPv6 PIM snooping neighbor information of all cards. (In standalone mode.)

chassis chassis-number slot slot-number: Displays the IPv6 PIM snooping neighbor information on a card in an IRF member device. The chassis-number argument represents the ID of the IRF member device, and the slot-number argument represents the number of the slot that holds the card. If this option is not specified, the command displays the IPv6 PIM snooping neighbor information of all cards in the IRF member devices. To obtain the chassis number and slot number, you can use the display device command. (In IRF mode.)

|: 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 display pim-snooping ipv6 neighbor to display IPv6 PIM snooping neighbor information.

Neighbor	IP address of the IPv6 PIM snooping neighbor.
Port	Name of the port that connects to the IPv6 PIM snooping neighbor.
Expires	Remaining time before the IPv6 PIM snooping neighbor expires. If the IPv6 PIM snooping neighbor never expires, this field displays never.
Option Flags	Possible values: ·     LAN Prune Delay—The IPv6 PIM hello messages received from the neighbor carry the LAN_Prune_Delay option. ·     LAN Prune Delay(T)—The IPv6 PIM hello messages received from the neighbor carry the LAN_Prune_Delay option, and the join suppression function has been disabled.

 

display pim-snooping ipv6 routing-table

Parameters

vlan vlan-id: Specifies a VLAN. The value range for the vlan-id argument is 1 to 4094. If no VLAN is specified, this command displays the IPv6 PIM snooping routing entries in all VLANs.

slot slot-number: Displays the IPv6 PIM snooping routing entries of the card specified by its slot number. If no slot is specified, the command displays information about the IPv6 PIM snooping routing entries on the MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Displays the IPv6 PIM snooping routing entries on a card in an IRF member device. The chassis-number argument represents the ID of the IRF member device, and the slot-number argument represents the number of the slot that holds the card. If this option is not specified, this command displays the IPv6 PIM snooping routing entries on all active MPUs in the IRF member devices. To obtain the chassis number and slot number, you can use the display device command. (In IRF mode.)

|: 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 display pim-snooping ipv6 routing-table to display the IPv6 PIM snooping routing table.

In standalone mode:

¡     To display the Upstream port field of an upstream interface that is not on the MPU, you must specify the slot slot-number option for the interface.

¡     To display the Expires and FSM fields of a non-aggregate interface that is not on the MPU, you must specify the slot slot-number option for the interface. There is no such restriction to aggregate interfaces.

·     In IRF mode:

¡     To display the Upstream port field of an upstream interface that is not on the MPU, you must specify the chassis chassis-number slot slot-number option for the interface.

¡     To display the Expires and FSM fields of a non-aggregate interface that is not on the MPU, you must specify the chassis chassis-number slot slot-number option for the interface. There is no such restriction to aggregate interfaces.

Description

Use pim-snooping ipv6 enable to enable IPv6 PIM snooping in a VLAN.

Use undo pim-snooping ipv6 enable to disable IPv6 PIM snooping in a VLAN.

By default, IPv6 PIM snooping is disabled.
