Configuring IGMP on AOS-Switches

In a network where IP multicast traffic is transmitted for various multimedia applications, Internet Group Management Protocol (IGMPInternet Group Management Protocol. Communications protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships.) helps reduce bandwidth usage on a per-port basis on a switch. Enabling IGMP for a VLANVirtual Local Area Network. In computer networking, a single Layer 2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them through one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN, or VLAN. allows the ports to detect IGMP queries and report packets, and manage IP multicast traffic through the switch.

By default, IGMP is disabled for all VLANs.

To enable IGMP for a VLAN, complete the following steps:

1. In the Network Operations app, select one of the following options:
   • To select a switch group in the filter:
     1. Set the filter to a group containing at least one switch.

        The dashboard context for the group is displayed.

     2. Under Manage, click Devices > Switches.
     3. Click the Config icon to view the switch configuration dashboard.
   • To select a switch in the filter:
     1. Set the filter to Global or a group containing at least one switch.
     2. Under Manage, click Devices > Switches.

        A list of switches is displayed in the List view.

     3. Click a switch under Device Name.

        The dashboard context for the switch is displayed.

     4. Under Manage, click Device.

        The tabs to configure the switch is displayed.

2. Click IGMP. The IGMP page is displayed with the list of existing VLANs.
3. Select the VLAN row(s) for which you want to configure IGMP, and click Edit.
4. Select Enable or Disable from the IGMP drop-down.
5. Click OK.
6. To configure the switch to filter unknown multicast messages, move the Filter Unknown Multicast toggle switch to the on position.
7. Click Save Settings.
