Operational Maximum
Response Time
This read-only field displays the value for maximum response time of IGMP
Snooping for the specified VLAN ID. Its value is learned dynamically from the
IGMPv2 or IGMPv3 queries received on this VLAN. For the multicast traffic not
to get disturbed, you should configure group membership interval to be
greater than this value.
Multicast Router Expiry Time
Enter the amount of time in seconds that a switch waits for a query to be
received on an interface before the interface is removed from the list of
interfaces with multicast routers attached. The range is 0 to 3600 seconds. A
value of 0 indicates an infinite time-out; i.e., no expiration.
