DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
NOTE: The robustness variable of the MLD snooping querier is used in creating the following
MLD message intervals:
Group Listener Interval – This is the amount of time that must pass before a multicast router
decides that there are no more listeners present of a group on a network. Calculated as
(robustness variable * query interval ) + (1 * query interval).
Querier Present Interval – This is the amount of time that must pass before a multicast router
decides that there are no other querier devices present. Calculated as (robustness variable *
query interval) + (0.5 * query response interval).
Last Listener Query Count – This is the amount of group–specific queries sent before the
router assumes there are no local listeners in this group. The default value is the value of the
robustness variable.
