Configure lms-ip in ap system-profile even if HA is used since it is used for looking up LACP striping IP.
(host) (config) #ap system-profile LACP
(host) (AP system profile "LACP") #lms-ip 192.0.2.1
(host) (AP system profile "LACP") #bkup-lms-ip 192.0.77.1
(host) (AP system profile "LACP") #write memory
Execute the following commands to configure AP LACP and striping IP on primary LMS or active HA controller:
(host) (config) #ap-lacp-striping-ip
(host) (AP LACP LMS map information) #striping-ip 192.0.2.2 lms 192.0.2.1
(host) (AP LACP LMS map information) #aplacp-enable
Execute the following commands to configure AP LACP LMS on HA standby or backup LMS.
(bkup-host) (config) #ap-lacp-striping-ip
(bkup-host) (AP LACP LMS map information) #striping-ip 192.0.77.2 lms 192.0.2.1
(bkup-host) (AP LACP LMS map information) #aplacp-enable
Using the WebUI in ArubaOS 6.3.1.x-6.4.1.x
Follow the procedure to configure the LACP parameters in AP System profile:
1. Navigate to the Configuration > Advanced Services > All Profiles page.
2. Expand the AP profiles menu in the Profiles pane
3. Expand the AP System profiles menu, and select the AP system profile you want to modify.
4. In the Profile Details pane, select the Basic tab, locate the LMS Settings section and a specify a unique
IPv4 address in the LMS IP field.
5. Click Apply.
Using the CLI in ArubaOS 6.3.1.x-6.4.1.x
Execute the following commands to configure the LACP parameters (LMS IP and the GRE striping IP) on an AP
system profile.
(host) (config) #ap system-profile LACP
(host) (AP system profile "LACP") #lms-ip 192.0.2.1
(host) (AP system profile "LACP") #gre-striping-ip 192.0.2.2
Execute the following commands to configure AP LACP LMS on HA standby or backup LMS.
If the lms-ip is not specified in the AP system profile, you can create an entry in ap-lacp-striping-ip profile with just
the striping-ip. The lms-ip value in the ap-system-profile is used as a key to look up entries in ap-lacp profile on all
the controllers that an AP can terminate on. This also helps in selectively disabling Ling Aggression on some APs by
not configuring lms-ip in their ap-system-profile.
Important Points to Remember
l In the upstream direction when the AP transmits GRE frames to the controller, the bonding driver must be
in active-active mode and not in the default active-standby mode to allow link aggregation.
l If an AP’s uplink access switch ports are configured in static port-channel mode, then the AP will set the
Ethernet bonding mode to static port-channel (xor mode) only if gre-striping-ip is configured. If gre-
striping-ip is not configured, then the AP goes back to active-standby mode. In this scenario, the AP may
go down depending on the behavior of the upstream switch.
l If an AP’s uplink access switch ports are configured in dynamic LACP mode, the AP detects LACP-PDUs and
automatically sets the Ethernet bonding mode to LACP. If gre-striping-ip is not configured, then the AP’s
Ethernet bonding mode will continue to be in LACP mode, but the AP will send GRE traffic only through one
Ethernet port.
