OMMANDS
By default, IGMP is disabled on an interface.
You must enable the multicast function before this command can work, you must
use this command first before you can configure other IGMP features.
Related command:
multicast routing-enable
.

CAUTION:
■
If the VLAN VPN is enabled on a port, the IGMP Snooping feature cannot be
enabled on the VLAN to which the port belongs, and the IGMP feature cannot
be enabled on the corresponding interface.
■
If IGMP Snooping feature is enabled on a VLAN, or IGMP is enabled on the
interface, you cannot add VLAN VPN enabled ports into the VLAN, and vice
versa.
Example
# Enable IGMP on Vlan-interface 10.
<SW8800> system-view
System View: return to User View with Ctrl+Z.
[SW8800]interface vlan-interface 10
[3Com-Vlan-interface10] igmp enable
igmp fast-leave
Syntax
igmp fast-leave
[
vlan
{
vlan-id
[
to
vlan-id
] } &<1-10> ]
undo igmp fast-leave
[
vlan
{
vlan-id
[
to
vlan-id
] } &<1-10> ]
View
Ethernet port view, system view
Parameter
vlan-id
: VLAN ID, which you want to configure the IGMP Snooping fast leave
feature on. The
value
range is from 1 to 4094.
Description
Use the
igmp fast-leave
command to enable IGMP fast leave on ports or VLANs.
Use the
undo igmp fast-leave
command to disable IGMP fast leave.
An IGMP-enabled Layer 3 switch does not query packets of the specific multicast
group to a fast leave-enabled port any longer when the port receives an IGMP
leave packet. Instead, the switch peels off the port from the multicast group
immediately.
You can optionally specify multiple
vlan
keywords for the
igmp fast-leave
command, through which you can enable IGMP fast leave in corresponding
VLANs. If you do not specify the
vlan
keyword, IGMP fast leave is enabled in all
VLANs. As mentioned earlier, the
igmp fast-leave
command can be executed in
both system view and Ethernet port view. When you execute the command in
system view, fast leave is enabled on all ports of the specified VLANs, otherwise, it
is only enabled on the current port in the specified VLANs.
