MLD snooping configuration
MLD snooping using MLDv1 with MLDv2
MLD snooping can be configured as MLDv1 or MLDv2 on individual ports on a VLAN. An interface
or router sends queries and reports that include the MLD version with which it has been
configured. The version configuration applies only to the sending of queries. The snooping device
recognizes and processes MLDv1 and MLDv2 packets regardless of the version configured.
NOTE
To avoid version deadlock, when an interface receives a report with a lower version than that for
which it has been configured, the interface does not automatically downgrade the running MLD
version.
MLD snooping configuration
Configuring MLD Snooping on Stackable devices consists of the following global and VLAN-specific
tasks.
Global tasks for MLD Snooping
• Configuring hardware and software resource limits
• Disabling transmission and receipt of MLD packets on a port
• Configuring the MLD mode: active or passive (must be enabled for MLD Snooping)
• Modifying the age interval
• Specifying the interval for query messages (active MLD mode only)
• Specifying the global MLD version
• Enabling and disabling report control (rate limiting)
• Modifying the leave-wait time
• Modifying the mcache age interval
• Disabling error and warning messages
VLAN-specific tasks for MLD Snooping
• Configuring the MLD mode for the VLAN: active or passive
• Enabling or disabling MLD Snooping for the VLAN
• Configuring the MLD version for the VLAN
• Configuring the MLD version for individual ports
• Configuring static groups to the entire VLAN or some ports
• Configuring static router ports
• Enabling client tracking and the fast leave feature for MLDv2
• Configuring fast leave for MLDv1
• Configuring fast-convergence
