changes.
Changes to the parameters take effect immediately on the stack.
3 - Host/Router
Timeout
Interval Specifies the time period in seconds after which the
stack determines that a host node has become inactive.
An inactive host node is a node that has not sent an
IGMP report during the specified time interval. The
range is from 1 second to 86,400 seconds (24 hours).
The default is 260 seconds.
This parameter also specifies the time interval used by
the stack in determining whether 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 during
the specified time interval, it assumes that the router is
no longer active on the port.
4 - Maximum
Multicast
Groups Specifies the maximum number of multicast groups the
stack will learn. The range is 1 to 255 groups. The
default is 64 multicast groups.
This parameter is useful with networks that contain a
large number of multicast groups. You could use the
parameter to prevent the stack’s MAC Address Table
from filling up with multicast MAC addresses, leaving
no room for dynamic or static MAC addresses.
