Link Aggregation Support on W-AP220 Series, W-AP270 Series, and
W-AP320 Series
W-AP220 Series , W-AP270 Series, and W-AP320 Series access points support link aggregation using either static
port channel (configuration based) or Link Aggregation Control Protocol (protocol signaling based). These
access points can optionally be deployed with LACP configuration to benefit from higher (greater than 1 Gbps)
aggregate throughput capabilities.
The controller uses two different IP addresses for forwarding traffic to wireless clients associated to tunnel
mode or decrypt-tunnel mode VAPs. One IP address is controller's IP address and the other is an unassigned IP
address called GRE striping IP. Select the GRE striping IP address to ensure that a different physical interface is
used by the load-balancing algorithm on the Ethernet switch. This enables the W-AP220 Series , W-AP270
Series, and W-AP320 Series access points achieve greater than 1 Gbps throughput in both upstream and
downstream directions.
On W-AP200 Series and W-AP270 Series access points, different IP addresses are used for different GRE
tunnels between the AP and the controller. One controller IP address is used for tunnels corresponding to
virtual APs using a 5G radio and the other controller IP address is used for tunnels corresponding to virtual APs
using a 2.4G radio. By associating clients on both bands you can achieve more than 1 Gbps throughput.
On W-AP320 Series access points, both IP addresses are used for GRE tunnels of virtual APs on 5G radio. By
associating one 4x4 802.11ac client or multiple clients on you can achieve more than 1 Gbps throughput.
ArubaOS 6.4.2.0 introduces a local AP LACP LMSmap information profile that maps a LMS IPaddress to a GRE
striping IP address. If the AP fails over to a standby or backup controller, the AP LACP LMSmap information
profile on the new controller defines the striping IP address that the AP uses for link aggregation. This feature
allows W-AP220 Series , W-AP270 Series, and W-AP320 Series access points to continue to support link
aggregation to a backup controller in the event of a controller failover, even if the backup controller is in a
different L3 network.
In previous releases, the GRE striping IP address was defined in the global AP system profile, which did not
allow APs to maintain GRE striping tunnels if the AP failed over to a backup controller in a different L3 network.
If your topology includes a backup controller you must define GRE striping IP settings in the active and the backup
controller. For more information on LACP features in ArubaOS, see Configuring LACP on page 153.
Configuring LACP
To enable and configure LACP on W-AP220 Series, W-AP270 Series, and W-AP320 Series access points,
configure the LMS IP address and the GRE Striping IP address. The GRE Striping IP does not belong to any
physical or virtual interface on the controller, but the controller can transmit or receive packets using this IP. In
ArubaOS 6.3.1.0 to 6.4.1.x, GRE striping is configured in the AP System profile. In ArubaOS 6.4.2 and later
versions, the GRE striping parameter is configured in the AP LACP Striping profile. This profile is local
configuration for a controller. It needs to be configured on all the controllers where a LACP AP can terminate,
that is, its lms/backup-lms or active/standby HA controllers.
You can configure LACP features using the WebUI or the CLI. The procedure varies, depending upon the
version of ArubaOS running on your controller.
