Note Multimedia Traffic Control with IP Multicast (IGMP) CLI: Configuring and Displaying IGMP 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. Note that this command must be executed in a VLAN context. 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. 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, refer to the chapter titled "Switch Memory and Configuration" in the Management and Configuration Guide for your switch. You can also combine the ip igmp command with other IGMP-related com­ mands, as described in the following sections. 2-9

Multimedia Traffic Control with IP Multicast (IGMP)
CLI: Configuring and Displaying IGMP
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. Note that this command must be
executed in a VLAN context.
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.
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
on how switch memory operates, refer to the chapter titled “Switch Memory
and Configuration” in the
Management and Configuration Guide
for your
switch.
You can also combine the ip igmp command with other IGMP-related com-
mands, as described in the following sections.
