ip igmp
You can enable IGMP on a VLAN, along with the last-saved or default IGMP configuration (whichever was most recently set), or you can disable IGMP on a selected VLAN.
Syntax:
[no] ip igmp
Enables IGMP on a VLAN. This command must be executed in a VLAN context.
Enable IGMP on VLAN 1
switch(vlan-1)# vlan 1 ip igmp
– or –
ip igmp
Disable IGMP on VLAN 1
switch(config)# no vlan 1 ip igmp
NOTE:
If you disable IGMP on a VLAN and then later re-enable IGMP on that VLAN, the switch restores the last-saved IGMP configuration for that VLAN. For more information, see the Management and Configuration Guide for your switch.
You can also combine the ip igmp
command with other IGMP-related commands, as described in the following
sections.
