Syntax

Command Default

The VLAN cannot forward multicast traffic to ports that do not receive IGMP membership reports.

Parameters
ipv4-address
Specifies the address of the static group.
count num
Specifies a contiguous range of groups.
ethernet unit/slot/port [ to unit/slot/port ]
Specifies a port or a range of ports to be included in the group.
LAG lag-id [ to lag-id ]

Usage Guidelines

A snooping-enabled VLAN cannot forward multicast traffic to ports that do not receive IGMP membership reports. You can configure the multicast static-group command to create a static group that applies to specific ports, allowing packets to be forwarded to them even though they have no client membership reports.

You can specify a list of ports, separated by a space, or a range of ports, or you can combine lists and ranges.

You can combine individual Ethernet ports, Ethernet port ranges, LAGs, and LAG ranges in the same command if you wish.

The no form of this command removes the static group from the VLAN.

Examples

This example configures a static group on VLAN 20 that contains ports 1/1/3 and 1/1/5 to 1/1/7.

device# configure terminal
device(config)# vlan 20
device(config-vlan-20)# multicast static-group 224.1.1.1 count 2 ethernet 1/1/3 ethernet 1/1/5 to 1/1/7
