VLAN Settings
Use the IGMP Snooping VLAN Settings to configure IGMP
Snooping settings for VLANs on the system. The Switch
performs IGMP Snooping on VLANs that send IGMP
packets. You can specify the VLANs that IGMP Snooping
should be performed on.. Choose from the drop-down
box whether to
Enable
or
Disable
IGMP Snooping. Next,
choose to
Enable
or
Disable
Fast Leave for the VLAN ID.
Click the
Apply
button
to accept the changes or the
Cancel
button
to discard them.
VLAN ID:
Displays the VLAN ID.
IGMP Snooping Status: Enables
or
Disables
the IGMP snooping
feature for the specified VLAN ID.
Fast Leave:
Enables
or
Disables
the IGMP snooping
Fast Leave for the specified VLAN ID.
Enabling this feature allows the Switch
to immediately remove the Layer 2
LAN port from its forwarding table
entry upon receiving an IGMP leave
message without first sending out
IGMP group-specific (GS) queries to the
port.
If Fast Leave is not used, a multicast querier will send
a GS-query message when an IGMPv2/v3 group leave
message is received. The querier stops forwarding traffic
for that group only if no host replies to the query within
the specified timeout period. If Fast Leave is enabled, the
Switch assumes that only one host is connected to the
port. Therefore, Fast Leave should only be enabled on a
port if it is connected to only one IGMP-enabled device.
Fast Leave is supported only with IGMPv2 or IGMPv3
Snooping when IGMP Snooping is enabled. Fast Leave
does not apply to a port if the Switch has learned that a
multicast querier is attached to it.
Fast Leave can improve bandwidth usage for a network
which frequently experiences many IGMP host add and
leave requests.
