config igmp_snooping querier
Parameters
• Other querier present interval—
Amount of time that must pass
before a multicast router decides
that there is no longer another
multicast router that is the querier.
This interval is calculated as
follows: (robustness variable x query
interval) + (0.5 x query response
interval).
• Last member query count— Number
of group-specific queries sent before
the router assumes there are no
local members of a group. The
default number is the value of the
robustness variable.
• By default, the robustness variable
is set to 2. You might want to
increase this value if you expect a
subnet to experience significant
packet loss.
last_member_query_interval <sec> − The
maximum amount of time between group-
specific query messages, including those
sent in response to leave-group messages.
You might lower this interval to reduce the
amount of time it takes a router to detect
the loss of the last member of a group.
state [enabled/disabled] − Allows the switch
to be specified as an IGMP Querier or Non-
querier.
Restrictions
Only administrator-level users can issue
this command.
