10.6.3 Setting the MLD Snooping Query Interval and Response
Interval
Context
The response time (max-response-time) of the MLD Snooping Query messages, including
General Query message and Group-Specific Query message, sent by the S3700 can be set
through commands. When a downstream device of the switch receives the Query message sent
by the switch, the downstream device starts a timer. When the timer value becomes 0, the
downstream device sends an MLD Snooping membership report message to the IPv6 multicast
group corresponding to the timer.
You should properly set the max-response-time parameter so that the switch can respond to the
MLD Snooping Query messages quickly. If the max-response-time is set improperly, a lot of
switches may send the membership report messages at the same time to congest the network
because the timers expire simultaneously.

NOTE
By default, the MLD snooping querier is disabled.
The MLD snooping querier does not participate in the election of the MLD querier; however, the MLD
snooping querier on an IPv6 multicast network running MLD may affect the election result because the
source IPv6 address of the Query message sent by the MLD snooping querier is small.
