Appendix B: Configuring Link
Aggregation (LACP) for AP
Backhaul
The ZoneFlex R710 can use link aggregation control protocol (LACP) as defined in
the 802.1ax (formerly 802.3ad) standard to control the bonding of two 1Gbps
physical Ethernet ports together to form a single 2Gbps logical link.
Link Aggregation and When To Use It
An access point such as the R710 is capable of passing wireless traffic in excess
of 1Gbps. This only occurs in extreme cases, such as during concurrent dual-band
operation over the widest possible channels and highest possible modulation and
coding scheme (MCS) rates in each band, with all traffic flowing in the same
direction. In such cases, a single Gigabit Ethernet backhaul will saturate and limit
the AP's capacity to less than 1Gbps.
To alleviate this backhaul limitation, link aggregation can be used to bond multiple
Gigabit Ethernet links into a single, high capacity logical link. The R710's link partner,
typically an Ethernet switch, must also support LACP and be configured to use this
feature.
Wi-Fi client capabilities and data demands should be considered before deploying
LACP for AP backhaul. For the vast majority of enterprise WLANs, single Gigabit
backhaul for APs is more than sufficient.
