Configuring the Switch
is determined by the IGMP Query Report Delay (see "Configuring IGMP Snooping
and Query Parameters" on page 3-207).
• If immediate leave is enabled, the switch assumes that only one host is connected
to the interface. Therefore, immediate leave should only be enabled on an interface
if it is connected to only one IGMP-enabled device, either a service host or a
neighbor running IGMP snooping.
• Immediate leave is only effective if IGMP snooping is enabled, and IGMPv2 or
IGMPv3 snooping is used.
Command Attributes
• VLAN ID – VLAN Identifier. (Range: 1-4093).
• Immediate Leave – Sets the status for immediate leave on the specified VLAN.
(Default: Disabled)
Web – Click IGMP Snooping, IGMP Immediate Leave. Select the VLAN interface to
