IPv6 PIM snooping commands

display ipv6 pim-snooping neighbor

Use display ipv6 pim-snooping neighbor to display IPv6 PIM snooping neighbor information.

Syntax

In standalone mode:

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 IPv6 PIM snooping neighbor information for all VLANs.

slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command displays IPv6 PIM snooping neighbor information for the MPU. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command displays IPv6 PIM snooping neighbor information for the global active MPU. (In IRF mode.)

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

Usage guidelines

IPv6 PIM snooping does not take effect on sub-VLANs of IPv6 multicast VLANs.

You must enable MLD snooping globally and for a VLAN before you enable IPv6 PIM snooping for a VLAN.

Examples

# Enable MLD snooping globally, and enable MLD snooping and IPv6 PIM snooping for VLAN 2.

Use ipv6 pim-snooping graceful-restart join-aging-time to set the aging time for global downstream ports and global router ports after an active/standby switchover.

Use undo ipv6 pim-snooping graceful-restart join-aging-time to restore the default.

Syntax

ipv6 pim-snooping graceful-restart join-aging-time seconds

Parameters

seconds: Specifies an aging time in the range of 210 to 18000 seconds.

Usage guidelines

You must enable IPv6 PIM snooping for a VLAN before you execute this command.

For a global router port or global downstream port, the set aging time does not take effect when the port receives an IPv6 PIM join message after an active/standby switchover. The aging time for the port is determined by the aging time in the IPv6 PIM join message.

Examples

# In VLAN 2, set the aging time to 600 seconds for global downstream ports and global router ports after an active/standby switchover.

<Sysname> system-view

[Sysname] mld-snooping
