Link Aggregation Control Protocol for OAW-IAP220 Series

OAW-IAP220 Series supports the IEEE 802.11ac standard for high-performance WLAN. To support maximum

traffic, port aggregation is required as it increases throughput and enhances reliability. To support port aggregation,

AOS-W 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 OAW-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.

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. OAW-IAP220 Series supports link aggregation using either

standard port-channel (configuration based) or Link Aggregation Control Protocol (protocol signaling based). OAW-

IAP220 Series can optionally be deployed with LACP configuration to benefit from the higher (greater than 1 Gbps)

aggregate throughput capabilities of the two radios.

LACP feature is supported only on OAW-IAP220 Series.

There is no configuration required on the APfor enabling LACP support. However, you can view the status of LACP

on OAW-IAPs by using the following command:

(Instant Access Point)# show lacp status
