Modify the leave latency of the network.The Last Member Query
Interval is the Max Response Time inserted into Group-Specific
Queries sent in response to Leave Group messages, and is also the
amount of time between Group-Specific Query messages. This value
may be tuned to modify the leave latency of the network. A reduced
value results in reduced time to detect the loss of the last member of a
group. The interval is in tenths of seconds. This value is not used if the
switch is not the querier. The field will initially display an asterisk (*).
Enter the IP address that the switch will use to source IGMP query
frames when the switch is the designated querier on the VLAN. The IP
address must be a valid address associated with the VLAN. The field
will initially display an asterisk (*).
NOTE: To prevent the switch from participating in the IGMP
querier election, this IP address must be set to
000.000.000.000.
Select the multicast pool size — the total number of multicast streams
supported — using the SPACE bar. Valid values are 16 to 512 in
increments of 16. Default is 32.
NOTE: Modifying the multicast pool size will require a reset
of the device.
See the address of the IGMP Querier on the IP subnet to which this
VLAN is attached. The field will initially display an asterisk (*).
See the number of seconds that the current IGMP Querier has been
operational since the last change in Queriers. The field will initially
display an asterisk (*).
See the number of seconds remaining before the Other Querier Present
Timer expires. If the local system (current device displayed) is the
querier, the value of this object is zero. The field will initially display
an asterisk (*).
