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 7 Enable IGMP on VLAN 1

HP Switch(vlan-1)# vlan 1 ip igmp

– or –

ip igmp

Example 8 Disable 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, see the Management

and Configuration Guide for your switch.
