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).

 

 

HP2512(config)# vlan 1 ip igmp

Enables IGMP on VLAN 1.

 

HP2512(vlan-1)# ip igmp

Same as above.

 

HP2512(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 appendic C, “Switch Memory and

 

Configuration”.

 

 

 

 

You can also combine the ip igmp command with other IGMP-related com- mands, as described in the following sections.
