configure stpd multicast send-query

configure stpd multicast send-query [on | off]


Configures suppressing IGMP- and MLD-triggered queries when STP topology changes are received.

Syntax Description

multicast Specifies multicast options.
send-query For VLANs associated with STPD, when topology changes occur, send or suppress IGMP or MLD queries.
on Send IGMP or MLD queries (default).
off Do not send IGMP or MLD queries.


Sending IGMP or MLD queries is on.

Usage Guidelines

Whenever STP topology changes are received on a port, the switch sends triggered queries that mark the peer port as a router port and floods all multicast packets towards this port. This can cause unnecessary bandwidth usage. This command allows you to allow or suppress this forwarding.


The following example turns off IGMP and MLD queries:

# configure stpd multicast send-query off
