Parameter
Description
Querier Mode
Select the desired setting, Auto, Fixed, or Edge. Auto means
the Switch uses the port as an IGMP query port if the port
receives IGMP query packets. Fixed means the Switch always
treats the port(s) as IGMP query port(s). This is for when
connecting an IGMP multicast server to the port(s). Edge means
the Switch does not use the port as an IGMP query port. In this
case, the Switch does not keep a record of an IGMP router
being connected to this port and the Switch does not forward
IGMP join or leave packets to this port.

Multicast Address
A multicast address is associated with a group of interested receivers. According to RFC
3171, addresses 224.0.0.0 to 239.255.255.255, the former Class D addresses, are
designated as multicast addresses in IPv4.
The IANA owns the OUI MAC address 01:00:5e, therefore multicast packets are delivered
by using the Ethernet MAC address range 01:00:5e:00:00:00 - 01:00:5e:7f:ff:ff. This is 23
bits of available address space.
