Global Settings; Igmp Querier - Hirschmann Power MICE Reference Manual

Switching

5.4.1 Global settings

"IGMP Snooping" allows you to enable IGMP Snooping globally for the entire
device.
If IGMP Snooping is disabled, then
the device does not evaluate Query and Report packets received, and
it sends (floods) received data packets with a Multicast address as the
destination address to all ports.
"GMRP" allows you to enable GMRP globally for the entire device.
It GMRP is disabled, then
the device does not generate any GMRP packets,
does not evaluate any GMRP packets received, and
sends (floods) received data packets to all ports.
The device is transparent for received GMRP packets, regardless of the
GMRP setting.
"inactive" disables GMRP and IGMP Snooping.

5.4.2 IGMP Querier

"IGMP Querier active" allows you to enable/disable the Query function.
The Protocol selection fields allow you to select IGMP version 1, 2 or 3.
In "Sending interval" you specify the interval at which the device sends query
packets (valid entries: 2-3599 s, default setting: 125 s). All IGMP-capable
terminal devices respond to a query with a report message, thus generating
a network load.
Select large sending intervals if you want to reduce the load on your network
and can accept the resulting longer switching times.
Select small sending intervals if you require short switching times and can
accept the resulting network load.
