The switch can filter multicast packets destined for the Universal Plug and Play (uPnP) multicast IP address with a Universal Plug and Play (uPnP) Filtering option. uPnP Filtering drops all incoming multicast packets received by a switch on an IGMP-enabled interface if the destination multicast IP address matches the configured range.
uPnP Filtering applies to both multicast receivers and multicast senders. If you want to use the uPnP Filtering address range for actual multicast streaming, you must disable uPnP Filtering on the IGMP interface.
uPnP Filtering is disabled by default. If you create a new IGMP interface, uPnP Filtering is enabled automatically on the interface for the destination multicast IP address range 239.255.255.250/32. If you enable uPnP Filtering on an existing IGMP-enabled interface with senders and receivers already present, the filter does not delete the existing senders or receivers; the filter begins to drop packets from that point forward. Existing senders and receivers eventually expire and senders are not relearned.
You can use CLI or EDM to configure a different destination multicast IP address range.
uPnP Filtering functions in the following scenarios:
IGMP snooping is enabled on a VLAN and IP Multicast over Fabric Connect on Layer 2 VSN is configured.
IP Multicast over Fabric Connect within the Global Routing Table (GRT) is configured.
IP Multicast over Fabric Connect on a Layer 3 VSN is configured.
