Figure 4-2. Example Listing of IGMP Configuration for A Specific VLAN

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. Note that this command must be executed in a VLAN context.

 

Syntax:

[no] ip igmp

 

For example, here are methods to enable and disable IGMP on the default

 

VLAN (VID = 1).

 

ProCurve(config)# vlan 1 ip igmp

 

Enables IGMP on VLAN 1.

 

ProCurve(vlan-1)# ip igmp

 

Same as above.

 

ProCurve(config)# no vlan 1 ip igmp

 

 

Disables IGMP on VLAN 1.

 

 

N o t e

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

 

on how switch memory operates, see the chapter on switch memory and

 

configuration in the Management and Configuration Guide.
