15. From the Exclude Mrouter Interface Mode menu, select to enable or disable the

Exclude Mrouter Interface Mode.

This selection specifies the type of information that is forwarded to the upstream
multicast router interface:

•

Enable. The VLAN forwards IGMP Join/Leave PDUs that it receives on a
downstream port to an upstream mrouter interface. In addition, the VLAN forwards
a multicast data stream to an upstream mrouter interface only if that port already
received an IGMPv1 or IGMPv2 membership message. The VLAN drops unknown
multicast streams. The default is Enable.

•

Disable: The VLAN forwards IGMP Join/Leave PDUs, known multicast streams,
and unknown multicast streams to the upstream mrouter interface.

NOTE: For information about IGMP Plus mode for VLANs, see Configure
IGMP snooping for VLANs automatically with IGMP Plus mode on page 313.

Configure an IGMP multicast router interface

You can configure an interface as the designated interface to which a multicast router
is attached. All IGMP packets snooped by the switch are forwarded to the multicast
router that is reachable from this interface. We refer to this interface as the multicast
router.

In most situations, this configuration is not required because the switch automatically
detects a multicast router and forwards IGMP packets accordingly. This configuration
might be required in a complex network if you want to make sure that the multicast
router always receives IGMP packets from the switch.

To configure a multicast router interface:

1. Launch a web browser.

2. In the address field of your web browser, enter the IP address of the switch.

If you do not know the IP address of the switch, see Log in to the main UI with a web
browser on page 27 and the subsections.
