 Host Topology— IGMP host topology. Choose between “Single”
which indicates a single host per port and “Multiple” 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— 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 255
seconds. Setting the timeout to zero (0) disables the timer.
 Maximum Groups— 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
multicast routers. Manual Router Ports Mode must be selected to
enter multicast router ports.
