MLD Snooping
To support selective IPv6 Multicast forwarding, bridge Multicast filtering must be enabled (in the Multicast >
Properties page), and MLD Snooping must be enabled globally and for each relevant VLAN in the MLD
Snooping pages.
To enable MLD Snooping and configure it on a VLAN:
STEP 1
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
• MLD Snooping Status—Select to enable MLD snooping globally on all interfaces.
STEP 3
• MLD Snooping Status—Select to enable MLD Snooping on the VLAN. The device monitors network
traffic to determine which hosts have asked to be sent Multicast traffic. The device performs MLD
snooping only when MLD snooping and Bridge Multicast filtering are both enabled.
• MRouter Ports Auto Learn—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.
• Last Member Query Counter—Number of MLD group-specific queries sent before the device
assumes there are no more members for the group, if the device is the elected querier.
- Use Query Robustness—This value is set in
