Controller-less WLANs

IAP-220 Series supports the IEEE 802.11ac standard for high-performance WLAN. To support maximum traffic, port aggregation is required as it increases  throughput to more than 1 Gbps.

To support port aggregation, Instant supports Link Aggregation Control Protocol (LACP) based on the IEEE 802.3ad standard. 802.3ad standard for Ethernet aggregation uses LACP as a method to manage link configuration and balance traffic among aggregated ports. LACP provides a standardized means for exchanging information with partner systems to form a dynamic link aggregation group. The LACP feature is automatically enabled during IAP boots and it dynamically detects the AP if connected to a partner system with LACP capability, by checking if there is any LACP Protocol Data Unit (PDU) received on either eth0 or eth1 port. This feature has no configuration; IAP will auto-detect LACP PDU in the uplink switch and enable LACP accordingly If the switch in the cluster has the LACP capability, you can combine eth0 and eth1 interfaces into the link aggregation group to form a single logical interface (port-channel). Port-channels can be used to provide additional bandwidth or link redundancy between two devices.

IAP-220 Series supports link aggregation using either standard port-channel (configuration based) or Link Aggregation Control Protocol (protocol signaling based). IAP-220 Series

can optionally be deployed with LACP configuration to benefit from the higher (greater than 1 Gbps) aggregate throughput capabilities of the two radios.
