Configuration guide | Set up a turnkey Wi-Fi solution for your business
Introduction
At HP, we understand that small business owners need simple, reliable wireless networks that can be supported with limited IT resources and still provide the connectivity required by today’s mobile employees. The HP Aruba 205 Wireless
Instant Access Point (IAP), when implemented with the HP 1920 Switch Series, provides businesses a Wi-Fi solution that
delivers superior performance, business grade security, resiliency, and flexibility with the simplicity of zero-touch
deployment. HP Aruba Instant is a turnkey, business-grade Wi-Fi Solution and does not require network expertise to deploy and manage.
HP 1920 Switch Series
The HP 1920 Switch Series, part of the HP OfficeConnect portfolio, is designed for smaller organizations dealing with bandwidth-demanding IAP applications. The switches are ideal for environments where smart-managed flexibility is a must for easy network configuration and management, and that require advanced features for granular control.
The HP 1920 Switch Series, features easy-to-use, out of the box, plug-and-play deployment. The series offers nine different rack-mountable models with internal power supplies including four non-Power over Ethernet (PoE) models: 8G-,
16G- , 24G-, and 48G-port; five PoE+ models: (2) 8G- , (2) 24G-, and 48G-port.
The 1920 Switch Series features an intuitive Web-managed interface for simple customization of network operation. The HP
1920 Switch Series delivers Layer 3 static routes, SFP ports, IPv6 support, rate limiting, link aggregation, and IGMP. The switches come with a limited lifetime warranty covering the unit, fans, and power supplies, as well as 24x7 phone support for the first three years of ownership.

HP Aruba 205 IAP
The HP Aruba 205 802.11ac IAPs maximize mobile device performance in medium-density Wi-Fi environments. These compact dual-radio IAPs deliver wireless data rates up to 867 Mbps for 802.11ac and up to 300 Mbps for 802.11n-enabled mobile devices. They have four integrated omni-directional downtilt antennas and support two spatial streams. The 205
IAPs support up to 50 active devices per IAP.
They support the IEEE 802.11ac and 802.11n standards for high-performance WLAN. These access points use MIMO technology and other high-throughput mode techniques to deliver high-performance, 802.11n 2.4 GHz, and 802.11ac 5
GHz functionality while simultaneously supporting legacy 802.11a/b/g wireless services.

Architecture
An IAP has no centralized controller, but a virtual controller (VC) resides within each of the IAPs. In a multiple IAP deployment scenario, only the first IAP needs to be configured. After the first IAP is configured, the other IAPs inherit all the required configuration information from the VC of the first IAP. A single IAP automatically distributes the network. Simply power-up an IAP, configure it over the air, and plug in the other IAPs.
Management plane
The management plane of an IAP is centralized. The first IAP to boot becomes the VC. The self-elected VC acts as the single point of configuration for an IAP cluster. The GUI interface to the VC provides local configuration and monitoring of an IAP cluster. Cloud-based configuration and management options are also available using Aruba Central (public cloud) or
AirWave (private cloud).
Control plane
The control plane of an IAP is distributed. All functions like adaptive radio management (ARM) -auto channel/power assignment, IDS/IPS, client handover, etc., are handled by the individual IAPs. The VC IAP is not involved in any of these functions. For example: The client database is completely maintained in the IAP that the clients are connected to. When a client roams, the new IAP figures out the last associated IAP for the client and requests all the client info from that IAP. The other IAPs send updates to VC IAP periodically only for management plane reporting.
Data plane
The data plane of an IAP is distributed. Each individual IAP handles the traffic for the clients associated to that IAP. The firewall policies and bandwidth control also gets applied on a per IAP basis. There is no centralized flow of all user traffic to the VC.

Configuration guide | Set up a turnkey Wi-Fi solution for your business
IAP cluster
IAPs in the same VLAN automatically find each other and form a single functioning network managed by a VC. When you make configuration changes on a VC, all associated IAPs in the cluster inherit these changes and subsequently update their configurations. Moving an IAP from one cluster to another requires a factory reset of the IAP.
All IAPs in a cluster use the same SSID configuration including master and slave IAPs. However, if you want to assign an SSID to a specific IAP, you can configure zone settings for an IAP.
Note:
For configuring zone settings on an IAP, see the Aruba IAP user guide.

Configuring the Aruba 205 Instant Network
Before installing an IAP:
1.
Ensure that you have an Ethernet cable of the required length to connect the IAP to the switch.
2.
Ensure that you have one of the following power sources:
A.
IEEE 802.3af/at–compliant Power over Ethernet (PoE) source. In this case, the switch is the PoE source.
B.
IAP power adapter kit.
Connecting an IAP
Based on the type of the power source used, perform one of the following steps to connect an IAP to the power source:
1.
PoE switch–Connect the ENET port of the IAP to port 2 on the 1920 PoE switch. The IAP powers on as soon as the ports are connected. To power on/off the IAP, disconnect the ENET port and reconnect.
2.
AC to DC power adapter–Connect the 12V DC power jack socket to the AC to DC power adapter.
DHCP IP address of the IAP
The IAP needs an IP address for network connectivity. When you connect an IAP to a port on the switch, it receives an IP address from a DHCP server.
To obtain an IP address for an IAP:
1.
Ensure that the DHCP service is enabled on the network.
2.
The IAP receives an IP address provided by the DHCP server the 1920 switch is connected to.
Note:
If there is no DHCP service on the network, the IAP can be assigned a static IP address. If a static IP is not assigned, the IAP obtains an IP automatically within the 169.254 subnet. The IAP and the 1920 switch need to be on the same network.
Configuration guide | Set up a turnkey Wi-Fi solution for your business
Accessing the instant CLI
You can verify the IP address of the IAP by logging into the IAP. Instant supports the use of Command Line Interface (CLI) for scripting purposes. When you make configuration changes on a master IAP in the CLI, all associated IAPs in the cluster inherit these changes and subsequently update their configurations. By default, you can access the CLI from the serial port or from an SSH session. You must explicitly enable Telnet access on the IAP to access the CLI through a Telnet session.
Connecting to a CLI session
1.
Connect a terminal or PC/workstation running a terminal emulation program to the console port on the IAP.
2.
Configure the terminal or terminal emulation program to use the following communication settings:
Table 4. Terminal communication settings
Baud rate Data bits Parity Stop bits Flow control
9600 8 None 1 None
On connecting to a CLI session, the system displays its host name followed by the login prompt. Use the administrator credentials to start a CLI session. For an IAP:
Username – admin
Password - admin
For example:
(Instant IAP) User: admin
If the login is successful, the privileged command mode is enabled and a command prompt is displayed. For example:
(Instant IAP)#
To verify the IP provided to the IAP by the DHCP server, run the “show ip interface brief” command.
(Instant IAP)# show ip interface brief
This command displays a summary of IP related information for all interfaces configured on an IAP.
The privileged mode provides access to show, clear, ping, traceroute, and commit commands. The configuration commands are available in config mode. To move from privileged mode to the configuration mode, enter the following command at the command prompt:
(Instant IAP)# configure terminal
The configure terminal command allows you to enter the basic configuration mode and the command prompt is displayed as follows:
(Instant IAP)(config)#
The Instant CLI allows CLI scripting in several other sub-command modes to allow the users to configure individual interfaces, SSIDs, access rules, and security settings.
You can use the question mark (?) to view the commands available in a privileged mode, configuration mode, or sub-mode.
Note:
Although automatic completion is supported for some commands such as configure terminal, the complete exit and end commands must be entered at command prompt. For more details on the IAP CLI, see the Aruba IAP user guide.

Configuration guide | Set up a turnkey Wi-Fi solution for your business
Assigning a static IP
It is highly recommended to connect the 1920 to a DHCP server so that the IAPs can get IP from the DHCP server too. In a multiple IAP scenario, it is not recommended to use Static IPs on the IAPs.
If you’re not using a DHCP server, you can assign a static IP to an IAP in the same network as the 1920 switch.
1.
Connect a terminal, PC, or workstation running a terminal emulation program to the console port on the IAP.
2.
Power on the IAP (i.e.; connect port 2 of the switch to console port of the IAP). An autoboot countdown prompt that allows you to interrupt the normal startup process and access IAP boot is displayed.
3.
Click Enter before the timer expires. The IAP goes into the APboot mode.
4.
In the APboot mode, use the following commands to assign a static IP to the IAP (IAP’s gateway ip is the IP of the 1920 switch)
Hit <Enter> to stop autoboot: 0
APboot>
APboot> setenv ipaddr 192.168.1.6
