Configuring the Switch
3-108
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: Enabled)
• 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: 5-30 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: 1-2; Default: 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.
