• Last Listener Query Interval—Displays the amount of time the switch
waits after it sends a query on an interface, participating in the VLAN,
because it did not receive a report for a particular group on that interface.
This value may be configured.
• Multicast Router Present Expiration Time — Displays the amount of time
to wait before removing an interface that is participating in the VLAN
from the list of interfaces with multicast routers attached. The interface is
removed if a query is not received. This value may be configured.

in response to a query to the router.
