• IGMP Query Count — Sets the maximum number of queries 
issued for which there has been no response before the switch 
takes action to drop a client from the multicast group. (Default: 
2, Range: 2 - 10)
• IGMP Query Interval — Sets the frequency (in seconds) at 
which the switch sends IGMP host-query messages. (Default: 
125, Range: 60 - 125)
• IGMP Report Delay — Sets the time (in seconds) between 
receiving an IGMP Report for an IP multicast address on a port 
before the switch sends an IGMP Query out of that port and 
removes the entry from its list. (Default: 10, Range: 5 - 30)
• Query Timeout — The time the switch waits after the previous 
querier stops before it considers the router port (i.e., the 
interface which had been receiving query packets) to have 
expired. (Default: 300 seconds, Range: 300 - 500)
• IGMP Version — Sets the protocol version for compatibility 
with other devices on the network. (Default: 2, Range: 1 - 2)
Notes: 1. All systems on the subnet must support the same 
version. 
2. Some attributes are only enabled for IGMPv2, including 
IGMP Report Delay and IGMP Query Timeout.
