Command Attributes

• IGMP Status — When enabled, the switch will monitor network traffic

to determine which hosts want to receive multicast traffic. This is also

referred to as IGMP Snooping. (Default: Enabled)

• Act as IGMP Querier — When enabled, the switch can serve as the

Querier, which is responsible for asking hosts if they want to receive

multicast traffic. (Default: Disabled)

• 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. (Range: 2-10, Default: 2)

• IGMP Query Interval — Sets the frequency at which the switch sends

IGMP host-query messages. (Range: 60-125 seconds, Default: 125)

• IGMP Report Delay — Sets the time 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. (Range:

5-25 seconds, Default: 10)

• IGMP 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. (Range: 300-500

seconds, Default: 300)

• IGMP Version — Sets the protocol version for compatibility with other

devices on the network. (Range: 1-3; Default: 2)

Notes: 1. All systems on the subnet must support the same version.

2. Some attributes are only enabled for IGMPv2 and v3,

including IGMP Report Delay and IGMP Query Timeout.
