Enabling or disabling IGMP on a VLAN
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.
Example 8 Enabling IGMP on VLAN 1
HP Switch(vlan-1)# vlan 1 ip igmp
– or –
HP Switch(vlan-1)# ip igmp
Example 9 Disabling IGMP on VLAN 1
HP 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 on how switch
memory operates, see the chapter "Switch Memory and Configuration" in the Management and
Configuration Guide for your switch.
