IGMP Snooping
This page enables customers to setup the configuration of IGMP Snooping. IGMP Snooping monitors IGMP
service requests passing between multicast clients and servers, and dynamically configures the ports which
need to receive the mulitcast traffic. For IGMPV3, basic support for reports only, and Source Multicast is not
supported.
Settings
If the network has adequate performance and security for your current needs, it is recommended that you leave
the VLAN settings in the default configuration. The default configuration is as follows:
All ports are members of VLAN 1
The switch management interface is on VLAN 1 (this cannot be changed)
All ports have a Port VLAN ID (PVID) of 1
All ports can send and receive both VLAN-tagged and untagged packets (i.e. they are “hybrid”
ports)
