Note: Multicast routers use this information, along with a multicast
routing protocol such as DVMRP or PIM, to support IP
multicasting across the Internet.
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: Disabled)
• 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. (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)
