IGMP Querier Version—Select the IGMP version used if the device
becomes the elected querier Select IGMPv3 if there are switches and/or
Multicast routers in the VLAN that perform source-specific IP Multicast
forwarding
•
Querier Source IP Address—Select the source IP address of the IGMP
Querier The following options are available:
•
Auto—The system decides whether to use the IP address of the VLAN
or the management IP address
•
User Defined—This can be the IP address of the VLAN or it can be the
management IP address
STEP 4 Click Apply The Running Configuration file is updated
MLD Snooping
To enable MLD Snooping and configure it on a VLAN, do the following:
STEP 1 Click Configuration > Multicast > MLD Snooping
When MLD Snooping is globally enabled, the device monitoring network
traffic can determine which hosts have requested to receive Multicast traffic
The device performs MLD Snooping only if both MLD snooping and Bridge
Multicast filtering are enabled
STEP 2 Select MLD Snooping to enable the feature
The following fields are displayed in the MLD Snooping Table:
•
VLAN ID-VLAN ID on which MLD snooping is defined
•
MLD Snooping Status-Whether the monitoring of network traffic for the
selected VLAN is enabled or disabled
•
Router MLD Version-MLD version supported
•
Auto Learn MRouter Ports -Whether auto learning of the ports to which
the Mrouter is connected is enabled
•
Immediate Leave-Whether Immediate Leave to decrease the time it takes
to block a Multicast stream sent to a member port when an MLD Group
Leave message is received on that port is enabled
STEP 3 Click Edit
STEP 4 Enable or disable the following features for the selected VLAN:
•
VLAN ID—Select a VLAN on which to configure MLD Snooping
•
MLD Snooping Status—Select to enable MLD snooping globally on all
interfaces
•
Auto-Learn MRouter Ports—Select to enable Auto Learn of the
Multicast router
•
Immediate Leave—Select to enable the switch to remove an interface
that sends a leave message from the forwarding table without first
sending out MAC-based general queries to the interface When an MLD
Leave Group message is received from a host, the system removes the
host port from the table entry After it relays the MLD queries from the
Multicast router, it deletes entries periodically if it does not receive any
MLD membership reports from the Multicast clients When enabled, this
feature reduces the time it takes to block unnecessary MLD traffic sent to
a device port
STEP 5 Click Apply The Running Configuration file is updated
Multicast Router Ports
A Multicast router (Mrouter) port is a port that connects to a Multicast router
The device includes the Multicast router port(s) numbers when it forwards the
Multicast streams and IGMP/MLD registration messages This is required so that
the Multicast routers can, in turn, forward the Multicast streams and propagate
the registration messages to other subnets
To statically configure or see dynamically-detected ports connected to the
Multicast router, do the following:
STEP 1 Click Configuration > Multicast > Multicast Router Ports
STEP 2 Enter some or all of following query filter criteria:
•
VLAN ID—Select the VLAN ID for the router ports that are described
•
IP Version—Select whether the IP group address is an IPv4 or IPv6
address
•
Interface Type—Select whether to display ports or LAGs
STEP 3 Click Search The interfaces matching the query criteria are displayed
STEP 4 For each port or LAG, select its association type The options are as
follows:
•
Static—The port is statically configured as a Multicast router port
