The parameters of role, country code, and IP address of the master controller are collectively known as the
provisioning parameters.
Provisioning Modes for branch deployments
The administrator has the choice of several provisioning modes that alter how the branch controller is supplied
with its own IP address, role, country code, and branch config group.
During the various provisioning modes, the branch controller is supplied with the IP address of the master
controller. Once the branch controller learns the IP address of the master controller, the branch controller
contacts the master controller and retrieves its branch config group.
Provisioning a controller means defining the following values for that device:
l the role of the controller (master or branch)
l the country code
l local configuration settings
ArubaOS supports the following provisioning modes for branch controllers:
l auto: In this mode, branch controller:
n obtains its IPaddress from DHCP
n obtains its role, country code, and the IP address of the master controller from either DHCP Options or a
provisioning rule in
n retrieves its branch config group from the master controller
l mini-setup: In this mode, the branch controller:
n has its role set to branch when mini-setup is initiated
n obtains its IP address from DHCP
n is configured with its country code and the IP address of the master controller through the console
n retrieves its branch config group from the master controller
l full-setup: In this mode, the branch controller:
n is configured with its role set to branch through the console
n is configured to obtain its IP address through manual configuration of a static IP, DHCP, or PPPoE
n is configured with its country code and the IP address of the master controller through the console
n retrieves its branch config group from the master controller.
Automatically Provisioning a Branch Controller
When a factory-default branch controller boots, it starts the auto-provisioning process.
First it will obtain its IP address through DHCP by sending a DHCP discover on the default uplink port. The
default uplink port is configured as an access port in VLAN 4094.
Second, it will attempt to retrieve the provisioning parameters from the DHCP options in the DHCP lease it has
obtained.
Next, if the provisioning parameters could not be obtained from the DHCP options, the branch controller will
attempt to retrieve the provisioning parameters from .
If the branch controller is unsuccessful in retrieving the provisioning parameters from , it will retry in 30
seconds.
The branch controller will keep trying to retrieve the provisioning parameters from every 30 seconds until it is
successful or the administrator interrupts Auto-Provisioning by initiating mini-setup or full-setup.
