IGMP snooping reduces duplicate and excess traffic on the network by
forwarding IP multicast traffic to specific switch ports rather than by flooding
all ports. With IGMP snooping, only ports that are members of specific IP
multicast groups receive multicast messages. The result is a more efficient
use of bandwidth.
Note
Disabling STP can affect connectivity to the network. Disabling IGMP snooping
can adversely affect the network performance.
Use the VLANs Advanced window (
Figure 3-8
) to change the STP and IGMP
snooping settings. To display this window, choose Configure > VLANs from the
device manager menu, and then click the Advanced button on the VLANs
window. See the device manager online help for additional guidelines and
procedures.
