igmp-snooping group-policy qinq pe-vid ce-vid

Function

The igmp-snooping group-policy qinq pe-vid ce-vid command limits the range of multicast groups that hosts can join.

The undo igmp-snooping group-policy qinq pe-vid ce-vid command cancels the configuration.

By default, hosts can join any multicast group.

Format

igmp-snooping group-policy { acl-number | acl-name acl-name } [ version number ] qinq pe-vid vlan-id ce-vid { vid1 [ to vid2 ] } &<1-10>

undo igmp-snooping group-policy [ { acl-number | acl-name acl-name } [ version number ] ] qinq pe-vid vlan-id ce-vid { vid1 [ to vid2 ] } &<1-10>

Parameters

Parameter	Description	Value
acl-number	Specifies the number of an ACL.	The value is an integer ranging from 2000 to 3999.
acl-name acl-name	Specifies the name of a named ACL.	The value is a string of 1 to 64 case-sensitive characters, spaces not supported. The name must start with a letter or digit, and cannot contain only digits.
version number	Specifies the version number of IGMP packets.	The value is an integer that is 1, 2, or 3.
vlan-id	Specifies an outer VLAN ID for a QinQ termination sub-interface.	The value is an integer ranging from 1 to 4094.
vid1	Specifies the VLAN range of multicast groups to which the group policy will be applied. vlan-id1 specifies the start VLAN ID.	The value is an integer ranging from 1 to 4094.
to vid2	Specifies the VLAN range of multicast groups to which the group policy will be applied. to vlan-id2 specifies the end VLAN ID.If the to vlan-id2 parameter is not specified, the group policy is effective only for the multicast groups that have the specified start VLAN ID.	The value is an integer ranging from 1 to 4094. vlan-id2 must be greater than vlan-id1. vlan-id2 and vlan-id1 specify a VLAN range.

Usage Guidelines

Usage Scenario

The igmp-snooping group-policy command is used to limit the range of multicast groups that user hosts can join.

Prerequisites

IGMP snooping has been enabled globally and in a VLAN.

Rules have been configured for a specified basic ACL.

Configuration Impact

After the igmp-snooping group-policy command is run, user hosts cannot join multicast groups beyond the configured multicast group range. If the igmp-snooping group-policy command is run more than once, all configurations take effect.

Precautions

If no IGMP version is specified, the device will apply the configured group policy to all IGMP messages (IGMPv1/IGMPv2/IGMPv3 messages) and the ACL configured for the group policy must be a basic ACL.

Example

# Allow the user hosts connected to GE 0/1/1.1 to join only multicast group 225.1.1.123.
