The output of the show profile-hierarchy CLI command shows how profiles relate to each other, and how
some higher-level profiles reference other lower-level profiles. The output of this command will vary,
depending upon controller configuration and licenses.
Viewing Profile Errors
To view the list of profile errors using the CLI, use the show profile-errors command. The WebUI displays
them with a flag icon next to the main horizontal menu (Figure 51). Click the flag to view the list of errors.

Before you Deploy an AP
Before you install APs in a network environment, you must ensure that the APs are able to locate and connect
to the controller. Specifically, you must configure firewall settings to allow APs to obtain software images and
configuration settings from the controller, verify APs are able to locate the controller, and verify each AP is
assigned a valid IP address when connected to the network. If you want to provision APs with more than one
interface, you can also configure the USB settings and interface priority levels using an AP provisioning profile.
The following steps describe the basic pre-deployment tasks. Click any of the links for more information on
these procedures.
1. Configure Firewall Settings
2. Enable Controller Discovery
3. Enable DHCP
4. (Optional) Define the AP Provisioning Profile
5. Define a virtual AP profile, and assign that profile to an AP group
Mesh AP Preconfiguration
Mesh APs require the following additional steps to define the mesh networking environment.
l Define and configure the mesh cluster profile.
l Define and configure the mesh radio profile
Remote AP Preconfiguration
Remote APs require the following additional step to identify valid APs in the remote AP whitelist.
l Create a Remote AP whitelist
Enable Controller Discovery
An AP can discover the IP address of the controller from a DNS server, from a DHCP server, or using the
ArubaDiscovery Protocol (ADP).
At boot time, the AP builds a list of controller IP addresses and then tries these addresses in order until it
successfully reaches a controller . This list of IP addresses provides an enhanced redundancy scheme for
controllers that are located in multiple data centers separated across Layer-3 networks. The AP constructs its
list of controller addresses as follows:
