Manage multicast
Multicast IP traffic is traffic that is destined to a host group. Host groups are identified
by Class D IP addresses, which range from 224.0.0.0 to 239.255.255.255.
Internet Group Management Protocol (IGMP) snooping allows the switch to forward
multicast traffic intelligently. Based on the IGMP query and report messages, the switch
forwards traffic only to the ports that request multicast traffic, rather than to all ports,
which could affect network performance.
IGMP snooping helps to optimize multicast performance and is especially useful for
bandwidth-intensive IP multicast applications such as online media streaming
applications.
Manage IGMP snooping
IGMP snooping is enabled by default. Under some circumstances you might want to
temporarily disable IGMP snooping.
To manage IGMP snooping:
1.
Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.
3. Enter the device management password.
The password is the one that you specified the first time that you logged in. The
password is case-sensitive.
The HOME page displays.
4.
From the menu at the top of the page, select SWITCHING.
The QOS page displays.
5.
From the menu on the left, select MULTICAST.
The MULTICAST page displays.
6. Enable or disable IGMP snooping by clicking the toggle in the IGMP Snooping
section.
When IGMP snooping is enabled, the toggle bar displays green.
7. Click the APPLY button.
Your settings are saved.
