The Max Response Time field allows an entry between 1 and 25 (seconds). The default is 10.
Query Interval

The Query Interval field is used to set the time (in seconds) between transmitting IGMP
queries. Entries between 1 and 65535 seconds are allowed. The default is 125.
Last Listener
Query Interval
(1-25)
This field specifies the maximum amount of time between group-specific query messages,
including those sent in response to leave group messages. The default is 1.
Robustness Value
(1-255)
Adjust this variable according to expected packet loss. If packet loss on the VLAN is expected
to be high, the Robustness Variable should be increased to accommodate increased packet
loss. This entry field allows an entry of 1 to 255. The default is 2.
Querier State
Choose Enabled to enable transmitting IGMP query packets or Disabled to disable the
transmitting of IGMP query packets. The default is Disabled.
Fast Done
This parameter allows the user to enable the Fast Leave function. Enabled, this function will
allow members of a multicast group to leave the group immediately (without the
implementation of the Last Member Query Timer) when an IGMP Leave Report Packet is
received by the Switch. The default is Disabled.

Querier Role
This read-only field describes the behavior of the Switch for sending query packets. Querier will
denote that the Switch is sending out IGMP query packets. Non-Querier will denote that the
Switch is not sending out IGMP query packets. This field will only read Querier when the
Querier State and the State fields have been Enabled.
