Host Topology— Specifies the IGMP host topology. Choose
between “Single” which indicates a single host per port and
“Multicast” which indicates multiple hosts per port. Select the
single-host per port setting when the switch has one-host-node per
port. Select the multiple setting when the switch has more than one
host-node per port. By default, the switch is set to “Single.”
Host/Router Timeout— Indicates the time, in seconds that the
switch times out when it finds inactive host nodes and multicast
routers. The range is from 0 to 86,400 seconds (24 hours). The
default is 260 seconds.Setting the timeout to zero (0) disables the
timer.
Maximum Groups— Specifies the maximum number of multicast
addresses the switch is allowed to learn. The range is 0 to 255
multicast addresses. If your network has a large number
of multicast groups, use this parameter to limit the number of
multicast groups the switch supports.The default is 64.
Router Ports Mode— Specifies ports that are connected to
multicast routers either manually or automatically. Manually
specifying multicast router ports deactivates auto-detect. To
reactivate auto-detect, select “Automatic.” Choose between
“Manual” and “Automatic.”
Router Ports— Specifies ports that are manually connected to
