Figure 278: Configuring General Settings for MLD Snooping
Setting Immediate
Leave Status for
MLD Snooping
per Interface
Use the Multicast > MLD Snooping > Interface page to configure Immediate Leave
status for a VLAN.
Parameters
These parameters are displayed:
◆
VLAN – A VLAN identification number. (Range: 1-4094)
◆
Immediate Leave Status – Immediately deletes a member port of an IPv6
multicast service when a leave packet is received at that port and immediate
leave is enabled for the parent VLAN. (Default: Disabled)
If MLD immediate-leave is not used, a multicast router (or querier) will send a
group-specific query message when an MLD group leave message is received.
The router/querier stops forwarding traffic for that group only if no host replies
to the query within the specified timeout period.
If MLD 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 MLD-enabled device, either a
service host or a neighbor running MLD snooping.
Web Interface
To configure immediate leave for MLD Snooping:
1.
Click Multicast, MLD Snooping, Interface.
2.
