Port IGMP Querier Mode
•
Auto
- The switch uses the port as an “IGMP Query Port” if the port receives
“IGMP Query” packets.
•
Fixed
- The switch always uses the port(s) as “IGMP Query Port(s)”. This
mode is used when connecting an IGMP multicast server to the port(s).
- The switch always forwards the clients “Report/Leave” packets to the
port. Normally, the port is connected to an IGMP server.
•
Edge
- The switch does not use the port as an “IGMP Query Port”.
- The “IGMP Query” packets received on this port are dropped.
Normally, the port is connected to an IGMP client.
Forwarding “IGMP Join/Leave” packets
The industrial managed switch will forward the “IGMP Join/Leave” packets to
the query port.
IGMP Proxy Snooping
The “IGMP Proxy Snooping” can reduce the number of “Reports” and “Leaves”
sent through an IGMP router.
Configurations
Users can enable/disable “IGMP Snooping” on the switch. This also applies to
specific VLANs. If “IGMP Snooping” on the switch is disabled, it is disabled on
all VLANs even when enabled on some VLANs.
VLAN States
There is a global state and individual VLAN states.
If the global state is disabled, “IGMP Snooping” on the switch is disabled even if
individual VLAN states have been enabled.
If the global state is enabled for “IGMP Snooping”, the function must be
individually enabled by the user for specific VLANs.
