Broadcast and multicast optimization

HPE Aruba Networking access points (APs) and gateways offer a suite of features that can be enabled to filter and/or optimize the forwarding and propagation of broadcast multicast traffic to wireless stations. For APs, options configured within each WLAN profile influences which broadcast multicast frames received by APs on either a LAN uplink or overlay tunnel are forwarded to wireless stations. The options also influence the transmit data rate that 802.11 broadcast multicast frames are transmitted by each radio in addition to converting specific broadcast multicast frames to unicast prior to transmission. All filtering and optimization options configured in a WLAN profiles apply to all forwarding modes.

For gateways, options enabled on each user VLAN influences which broadcast multicast frames received by gateways on either a LAN port or overlay tunnel are propagated and forwarded to APs and gateways. The options influence which broadcast multicast frames are replicated and forwarded for each overlay tunnel and if specific broadcast multicast frames are converted to unicast prior to forwarding. All filtering and optimization options configured on a user VLAN applies to tunnel forwarding mode.
