controllers for that AP. This feature does not require that the active controller act the configuration master for the local standby controller . A master controller in a master-local deployment can act as an active or a standby controller . When the AP first connects to its active controller, that controller sends the AP the IP address of a standby controller, and the AP attempts to connect to the standby controller. If an AP that is part of a cluster with multiple backup controllers fails to connect to the first standby controller, the active controller will select a new standby controller for that AP, and the AP will attempt to connect to that standby controller. APs using control plane security establish an IPsec tunnel to their standby controllers. APs that are not configured to use control plane security send clear, unencrypted information to the standby controller. An AP will failover to its backup controller if it fails to contact its active controller through regular heartbeats and keepalive messages, or if the user manually triggers a failover using the WebUI or CLI. A controller using this feature can have one of three high availability roles - active, standby or dual. An active controller serves APs, but cannot act as a failover standby controller for any AP except the ones that it serves as active. A standby controller acts as a failover backup controller, but cannot be configured as the primary controller for any AP. A dual controller can support both roles, and acts as the active controller for one set of APs, and also acts as a standby controller for another set of APs. Examples The following commands configures a high availability group, and assigns controllers and roles to each controller in the group. (host) (config) #ha group-profile new (host) (HA group information "new") #controller 192.0.2.2 role active (host) (HA group information "new") #controller 192.0.2.3 role active (host) (HA group information "new") #controller 192.0.2.4 role standby (host) (HA group information "new") #preemption Command History Version ArubaOS 6.3 Description Command introduced ArubaOS 6.4 The following parameters were introduced l heartbeat l heartbeat-interval l heartbeat-threshold l over-subscription l pre-shared-key l state-sync Command Information Platform Available on all platforms License Available in the base operating system.

controllers for that AP. This feature does not require that the active controller act the configuration master for

the local standby controller . A master controller in a master-local deployment can act as an active or a standby

controller .

When the AP first connects to its active controller, that controller sends the AP the IP address of a standby

controller, and the AP attempts to connect to the standby controller. If an AP that is part of a cluster with

multiple backup controllers fails to connect to the first standby controller, the active controller will select a new

standby controller for that AP, and the AP will attempt to connect to that standby controller. APs using control

plane security establish an IPsec tunnel to their standby controllers. APs that are not configured to use control

plane security send clear, unencrypted information to the standby controller.

An AP will failover to its backup controller if it fails to contact its active controller through regular heartbeats

and keepalive messages, or if the user manually triggers a failover using the WebUI or CLI.

A controller using this feature can have one of three high availability roles –

active

standby

dual

. An active

controller serves APs, but cannot act as a failover standby controller for any AP except the ones that it serves

as active. A standby controller acts as a failover backup controller, but cannot be configured as the primary

controller for any AP. A dual controller can support both roles, and acts as the active controller for one set of

APs, and also acts as a standby controller for another set of APs.

Examples

The following commands configures a high availability group, and assigns controllers and roles to each

controller in the group.

(host) (config) #ha group-profile new

(host) (HA group information "new") #controller 192.0.2.2 role active

(host) (HA group information "new") #controller 192.0.2.3 role active

(host) (HA group information "new") #controller 192.0.2.4 role standby

(host) (HA group information "new") #preemption
