Configures suppressing IGMP (Internet Group Management Protocol)- and MLD-triggered queries when STP (Spanning Tree Protocol) topology changes are received.
| 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.
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
This command was first available in ExtremeXOS 21.1.5-Patch1-2.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X590, X620, X690, X870 series switches.
