Using the CLI to configure the PSK
Master Controller
On the master controller you can configure a specific IPSec PSK for a local controller and use the localip 0.0.0.0
ipsec command:
localip 0.0.0.0 ipsec <secret_key>
localip <ipaddr> ipsec <secret_key>
Local Controller
On the local controller the secret key (PSK) must match the master controller’s PSK.
masterip <ipaddr> ipsec <secret_key> [fqdn <fqdn>][uplink][vlan <id>]
Configuring Local Controllers
A single master controller configuration can be one controller or a master redundant configuration with one
master controller and the VRRP redundant backup controller. This section highlights the difference in
configuration for both of these scenarios.
The steps involved in migrating from a single to a multi-controller environment are:
1. Configure the role of the local controller to local and specify the IP address of the master.
2. Configure the layer-2 / layer-3 settings on the local controller (VLANs, IP subnets, IP routes).
3. Configure as trusted ports the ports the master and local controller use to communicate with each other.
4. For those APs that need to boot off the local controller, configure the LMS IP address to point to the new
local controller.
5. Reboot the APs that are already on the network, so that they now connect to the local controller.
These steps are explained below.
Configuring the Local Controller
You configure the role of a controller by running the initial setup on an unconfigured controller, or by using the
WebUI, Controller Wizard, or CLI on a previously-configured controller.
Using the Initial Setup
Initial setup can be done using the browser-based Setup Wizard or by accessing the initial setup dialog via a serial
port connection. Both methods are described in the ArubaOS Quick Start Guide and are referred to throughout
this chapter as “initial setup.”
The initial setup allows you to configure the IP address of the controller and its role, in addition to other
operating parameters. You perform the initial setup the first time you connect to and log into the controller or
whenever the controller is reset to its factory default configuration (after executing a
write erase, reload
sequence).
When prompted to enter the controller role in the initial setup, select or enter local to set the controller
operational mode to be a local controller. You are then prompted for the master controller IP address. Enter the
Note: You need to change the secret key to a non-default PSK key value even if you use a per-local controller PSK key
configuration.
