Chapter 17: IGMP Snooping Commands

SET IP IGMP
Syntax
set ip igmp [snoopingstatus=enabled|disabled]
[hoststatus=singlehost|multihost] [timeout=
value ]
[numbermulticastgroups= value ]
[routerport= port |all|none|auto]
Parameters
snoopingstatus Activates and deactivates IGMP snooping
on the stack. The options are:
enabled Activates IGMP snooping.
disabled Deactivates IGMP snooping.
This is the default setting.
hoststatus Specifies the IGMP host node topology.
Options are:
singlehost Activates the Single-Host/Port
setting, which is appropriate
when there is only one host
node connected to a port on
the stack. This is the default
setting.
multihost Activates the Multi-Host
setting, which is appropriate if
there is more than one host
node connected to a stack port.
timeout Specifies the time period in seconds used by
the stack to identify inactive host nodes. A
host node is inactive if it has not sent an
IGMP report during the specified time
interval. The range is from 0 second to
86,400 seconds (24 hours). The default is
260 seconds. If you set the timeout to zero
(0), the timer never times out, and the
timeout interval is essentially disabled.
This parameter also controls the time
interval used in determining whether or not a
multicast router is still active. The stack
makes the determination by watching for
queries from the router. If the stack does not
detect any queries from a multicast router
