5.4 WAP Configuration

Sierra leverages an Aruba enterprise class wireless access point that runs Aruba’s Instant virtual controller software. The WAP can be configured through the Aruba web GUI, or through the console/sssh comm and line interface (CLI). The se ttings can be saved out t o, and loaded from, a configuration file.

The following example copies a configuration file to the tftp server:

sierra# copy config tftp 192.168.1.1 filename.cfg

The following example copies a configuration file to the WAP:

sierra# copy tftp 192.168.1.1 filename.cfg system config

reload (this command restarts the WAP)

To maximize video str eaming perform ance, the following sett ings have been incl uded in the default configuration file: /var/lib/tftpboot/SierraBlackLabel.cfg

• Wide channel bands are enabled, but channel width has been limited to 40MHz. This helps clients get on and off the air more quickly.

• Minimum transmit rates have been set to 12 Mbps. This prevents weaker clients from slowing down the network.

• Arp Broadcast filtering is enabled. This converts arp broadcasts to unicast.

• ARM Band Steering Mode is set to Balance Bands. This helps utilize both radios.

• The min/max power settings of the 5 GHz radio ha ve been set 6d bm higher than the 2.4

GHz radio. This accounts for the additional free space path loss and smaller receiver aperture associated with the higher frequencies.

7 WLAN Setup

There are four steps to creating an SSID:

1. Selec t the type of SSID you want to create. T he Employee and Voice selec tions will lead you to

802.1X and PSK authentication. The Guest option will lead you to Captive Portal authentication.

2. Configure the Vlan and client IP assignment.

3. The security stage depends on your wireless LAN setting selections. Enterprise will give you 802.1x

selections, personal will give you PSK or WEP selections. If you select guest you will receive

captive portal options.

4. The last stage is the settings for the firewall with the user rights.

These stages are shown below in Figure 7-1.

Figure 7-1: The Four Stages to Creating an SSID

Page | 30 Revision Date January 28, 2020 || Document Number UM-E71-314 || Rev A

astronics.com

Page 31

Step 1

You create SSIDs us ing the WLAN W izard. You launch the WLAN Wizard by selecting New f rom the Networks section on the main GUI page. This will bring up the WLAN Settings tab of the New WLAN dialog

box. The WLAN Settings tab is where you select the type of SSID you want to create and name the SSID, as shown below in Figure 7-2.

Figure 7-2: The WLAN Settings Tab of the New WLAN Dialog Box

Page | 31 Revision Date January 28, 2020 || Document Number UM-E71-314 || Rev A

astronics.com

Page 32

Step 2

The VLAN Tab is where you configure the VLAN assignment and client IP assignment. The available VLAN and client IP assignment options are shown below in Figure 7-3.

Figure 7-3: The VLAN Tab of the New WLAN Dialog Box

The two client IP assignment options are virtual controller Managed and Network assigned.

Virtual Controller Managed

The client will associate and authenticate to the access point. The access point will act as a relay agent to the virtual controller, and the virtual controller will provide and act as the DHCP server.

• The Access Points will be providing DHCP for any wireless clients that connect to this SSID.

• The SSID and IAPs will source NAT all client traffic onto the wire.

Page | 32 Revision Date January 28, 2020 || Document Number UM-E71-314 || Rev A

astronics.com

Page 33

Network Assigned

The client will associate and authenticate to the access point. The access points will act as a bridge and pass the traffic without modifying the original payload. DHCP will be provided by the DHCP server on the LAN. The APs will bridge the client traffic onto the wire without manipulating or modifying the packets.

• The AP will bridge the client traffic onto the wire.

• The AP turns the wireless frame into an Ethernet frame.

Step 3

The Security tab is where you set the security level. There are three levels; Open, Personal, and Enterprise. Selecting the Enterprise level allows you to configure an external RADIUS authentication server, as shown below in Figure 7-4.

Figure 7-4: Configuring an External RADIUS Server

astronics.com

Page 34

Step 4

The Access tab is wher e you configure the fire wall rules and user rights. The Access tab allows you to create Network-Based rules and Role-Based rules. You also have the option to leave the SSID Unrestricted. Figure 7-5 sho ws an exam ple of creating a rule that deni es all DNS traf fic except to the DNS server with the IP address of 192.168.10.1.

Figure 7-5: Configuring Firewall Rules

Refer to the Aruba Instant Users Guide for additional information on the IAP GUI.

Captive Portal SSID

The following is to create a Captive Portal SSID for your guests:

• In the WLAN Settings tab, select the Guest option.

• In the VLAN tab, select Netw ork Assign ed for Client IP Assignment and Default for Client VLAN

Assignment.

• In the Security ta b, select External for Splash Page Type, a nd then select the Edit button to edit

the default Captive Porta l P r ofile as shown below in Figure 7-6.

10.2.11 Installation Limitations

The Sierra is intended t o be ins tal led in t he bag bin of the cabin to pro vide ad equ ate RF co verage of the Wi-Fi signal. The Sierra shall maintain a minimum air gap spacing as follows:

• Bottom (G1) = 0.00”

• Left (G2) = 1.00”

• Right (G3) = 1.00”

• Top (G4) = 1.00”

• Front (G5) = 1.00”

• Rear (G6) = 1.00”

Installations violating the above air gap spacing must be approved by Astronics CSC engineering. There are no minimum installation distances between Sierras. The maximum distance shall be

determined by aircraft type and configuration and content (e.g. throughput considerations). Enclosures that fully encase the unit should be manufactured from materials that do not interfere with

the operation of the un it's a ntennas. Tr ansportab le en closur es suc h as bags s hould include sp acer s to ensure these minimum air gaps are maintained at all times.

The air gaps listed above represent minimum required distances between the Sierra's surfaces and a hypothetical enclos ure to ensure con tinued operatio n without overheat ing. Additional c onsideration should be given to the unit's front face to allow for access to the unit's battery bays, peripheral connections and the removable SSD if these elements are to be used while the unit is secured on the aircraft. The front door of the unit requires 1.75" of unobstructed area to open fully, and the batteries require a minimum of 6" of unobstructed area to be installed or removed. Allowance for these additional clearances may be satisfied by the addition of a door or a removable cover to the enclosure design.
