Figure 9-66. 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).
SMC TigerSwitch 10/100(config)# vlan 1 ip igmp
Enables IGMP on VLAN 1.
SMC TigerSwitch 10/100(vlan-1)# ip igmp
Same as above.
SMC TigerSwitch 10/100(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.
