24.1.3 IGMP Snooping
The Switch can passively snoop on IGMP packets transferred between IP multicast
routers/switches and IP multicast hosts to learn the IP multicast group
membership. It checks IGMP packets passing through it, picks out the group
registration information, and configures multicasting accordingly. IGMP snooping
allows the Switch to learn multicast groups without you having to manually
configure them.
The Switch forwards multicast traffic destined for multicast groups (that it has
learned from IGMP snooping or that you have manually configured) to ports that
are members of that group. IGMP snooping generates no additional network
traffic, allowing you to significantly reduce multicast traffic passing through your
Switch.
24.1.4 IGMP Snooping and VLANs
The Switch can perform IGMP snooping on up to 16 VLANs. You can configure the
Switch to automatically learn multicast group membership of any VLANs. The
Switch then performs IGMP snooping on the first 16 VLANs that send IGMP
packets. This is referred to as auto mode. Alternatively, you can specify the VLANs
that IGMP snooping should be performed on. This is referred to as fixed mode. In
fixed mode the Switch does not learn multicast group membership of any VLANs
other than those explicitly added as an IGMP snooping VLAN.
