Configuration Using the Web-based Utility

Multicast

Multicast configuration options include IGMP Snooping, Bridge Multicast, and Bridge Multicast Forward All.

Multicast > IGMP Snooping

Multicast > IGMP Snooping

When IGMP Snooping is enabled globally, all IGMP packets are forwarded to the CPU. The CPU analyzes the incoming packets and determines:

•Which ports want to join which Multicast groups

•Which ports have Multicast routers generating IGMP queries

•Which routing protocols are forwarding packets and Multicast traffic

Ports requesting to join a specific Multicast group issue an IGMP report, specifying that Multicast group is accepting members. This results in the creation of the Multicast filtering database.

The Bridge Multicast Forward All screen contains two sections, IGMP Global and VLAN IGMP Settings. These sections and the fields they contain are described below.

IGMP Global

Enable IGMP Snooping  Select this option to enable IGMP Snooping on the device. IGMP Snooping can be enabled only if Bridge Multicast Filtering is enabled. The default is disabled (option not selected).

VLAN IGMP Settings

VLAN ID  Select the VLAN ID from the drop-down menu.

IGMP Status  Select this option to enable IGMP snooping on the VLAN. Default is disabled (option not selected).

Auto Learn  Select this option to enable Auto Learn on the device. If Auto Learn is enabled, the device automatically learns where other Multicast groups are located. The default is enabled (option is selected).

Host Timeout  Indicates the amount of time host waits to receive a message before timing out. The default time is

260seconds.

MRouter Timeout  Indicates the amount of the time the Multicast router waits to receive a message before it times out. The default value is 300 seconds.

Leave Timeout  Indicates the amount of time the host waits, after requesting to leave the IGMP group and not receiving a Join message from another station, before timing out. If a Leave Timeout occurs, the switch notifies the Multicast device to stop sending traffic The Leave Timeout value is either user-defined, or an immediate leave value. The default timeout is 10 seconds.

Click Update to update the screen with your changes.

Click Save Settings to save the changes, or Cancel Changes to cancel the changes.

Multicast > Bridge Multicast

The Bridge Multicast screen displays the ports and LAGs attached to the Multicast service group in the Ports and LAGs tables. The Port and LAG tables also reflect the manner in which the port or LAGs joined the Multicast group.

Multicast > Bridge Multicast

Ports can be added either to existing groups or to new Multicast service groups. The Bridge Multicast screen permits new Multicast service groups to be created. The Bridge Multicast screen also assigns ports to a specific Multicast service address group.

The Bridge Multicast screen contains the following fields: Unit No.  Select the unit which you are managing.

VLAN ID  Identifies a VLAN to be configured to a Multicast service.

Bridge Multicast Address  Identifies the Multicast group MAC address/IP address.
