4Aruba 501 802.11ac Wireless Client Bridge Configuration and Administration Guide

The Aruba 501 securely connects legacy Ethernet or serial communications devices to a wireless local area
network (WLAN). It enables the deployment of legacy client devices, such as point-of-sale terminals, servers, and
printers, in any location where a WLAN signal is available, thus eliminating the need to install a cabling
infrastructure.
The following sections describe various deployment scenarios.
Connecting wired devices to a wireless network
In this scenario, the Aruba 501 connects two wired computers to a private network via a wireless connection. The
two computers are connected to a switch that is connected to the Ethernet port on the Aruba 501. A station profile
is defined on the Aruba 501 with the name of the wireless network provided by the upstream AP, and the required
credentials to log in. Once the Aruba 501 is connected to the private network, the computers obtain an IP address
from the DHCP server and can then communicate with resources on the private network.
For configuration instructions, see Using station profiles to establish a wireless link on page 25.
Connecting a wired device using MAC address cloning
In this scenario, the Aruba 501 makes a wired printer available to clients on the upstream wireless network. Prior
to this deployment, the printer’s MAC address was known by users from its previous placement on a wired
network. Although it is now available through a wireless connection, it is preferable for the wireless clients to
continue accessing the printer using the MAC address, so that they do not need to change any settings. The MAC
address cloning feature on the Aruba 501 is used to preserve the printer’s network identity. With MAC address
cloning, the Aruba 501 assigns the printer's MAC address to the Aruba 501 wireless port, making the Aruba 501
appear to be the printer on the upstream wireless network.
For configuration instructions, see Configuring MAC address cloning on page 31.

Connecting a serial device to a wireless network
TCP serial functionality allows devices that have no native Ethernet or wireless connectivity to access the network
through a serial port. In this scenario, the Aruba 501 enables a point-of-sale terminal to exchange traffic with a
remote host. The point-of-sale terminal is connected to the serial port on the Aruba 501. To connect it to a
wireless network, the Aruba 501 converts traffic between the serial data format and TCP/IP.
For configuration instructions, see TCP serial on page 41.
6Aruba 501 802.11ac Wireless Client Bridge Configuration and Administration Guide

The Aruba 501 is managed via its web-based management tool using Microsoft Internet Explorer 8 or later or
Mozilla Firefox 17 or later. You can access the Aruba 501 management tool using either HTTP or HTTPS. Using
HTTPS is more secure but you will see a security warning until you purchase and install your own certificate. With
HTTPS, it is acceptable to choose the option that allows you to proceed through the security warning.
In a web browser, specify either: http://192.168.1.1 or https://192.168.1.1. (By default, HTTP access is disabled
and any access from HTTP is automatically redirected to HTTPS.)
For information on launching the management tool for the first time, see the Aruba 501 802.11ac Wireless Client
Bridge Quickstart.
Configuring web server settings
Select Management > Management tool to open the Configure web server settings page.
You can configure the web server settings, change the user login name or password, and manage the certificate
file required for secure HTTP communication.
Web server configuration
Use this section to configure web access to the management tool.
HTTPS server status/HTTP server status
The Aruba 501 software includes HTTP and HTTPS functionality to enable communication with your web
browser. Unlike HTTP, HTTPS enables secure sessions using a digital certificate to encrypt data exchanged
between the Aruba 501 and your web browser. By default, HTTPS is enabled and HTTP is disabled. When HTTP
is disabled, requests from HTTP clients are redirected to use HTTPS.
The Aruba 501 supports only one management session at a time via HTTP or HTTPS.
HTTPS port/HTTP port
By default, the HTTP server uses the well-known logical port number 80 for communication with clients and the
HTTPS port uses port number 443. You can specify different port numbers in the range 1025 to 65535 if the
default ports are blocked or used for other protocols on your network.
Session timeout
If there is no activity on the management session for the specified time, then the administrator will be
automatically logged off. The default timeout is 5 minutes.

Chapter 2 Managing the Aruba 501 7

Administrator login configuration
The Aruba 501 supports one administrator login. Use this section to change the username and password.
Username
The default username is admin. The username can be from 1 to 32 alphanumeric characters including special
characters.
Current password
The default password is admin.
New password and Confirm password
Specify a new password for the Aruba 501 administrator account.
The administrator password can be from 1 to 32 alphanumeric characters including special characters. The
password cannot begin or end with a space. For security purposes, it is recommended that the password be at
least 6 characters.
If you forget the administrator password, the only way to access the administrator account is to reset
the Aruba 501 to factory default settings. See Resetting to factory defaults on page 71.
Managing HTTP SSL certificates
When HTTPS access is enabled, the Aruba 501 must be able to present a Secure Sockets Layer (SSL) certificate
to the web browser of a computer that attempts access to the management tool. The certificate assures that the
browser is accessing the Aruba 501 with the specified IP address. It also provides information that the Aruba 501
and management computer use to encrypt their communication.
A default certificate is present on the Aruba 501, based on the default device IP address 192.168.1.1. If you
change the Aruba 501 IP address, you must update the certificate to reflect the new address; otherwise, a
security warning will display at the start of each new management session. A certificate can also expire, requiring
you to obtain a new one.

Generate certificate
You can generate a new certificate directly using the Aruba 501 management tool, or you can upload a certificate
to the Aruba 501 from a computer or network location.
To generate a new certificate from the Management tool page, under Generate certificate, click Generate.
Certificate status
You can view the following information about the certificate in the Certificate status section of the Management
tool page:
Certificate file present
Indicates whether an HTTP SSL certificate file is present (yes or no).
Certificate expiration date
The date that the HTTP SSL certificate file will expire.
Certificate issuer common name
The common name attribute of the server certificate. The common name is often the fully qualified domain name
for the HTTP server, or the IP address equivalent.
Chapter 2 Managing the Aruba 501 9

Save certificate
You can save the current SSL certificate to a backup file.
Download method
Select a download method (HTTP or TFTP).
•HTTP: Select this option to save the certificate on a computer or network location.
•TFTP: Select this option to save the certificate on a TFTP server.
HTTP SSL certificate file
The file name of the certificate to be saved.
Server IP
The Server IP location to save the file.
Upload certificate
You can upload a new SSL certificate from another computer or network location:
Upload method
Select an upload method (HTTP or TFTP).
•HTTP: Choose this option if the certificate is located on a computer or network location.
•TFTP: Choose this option if the certificate is located on a TFTP server.
HTTP SSL certificate file
The file path and file name of the certificate to be uploaded.
Server IP
The Server IP location from which to upload the file.
Configuring a management access control list
You can create an access control list (ACL) that lists hosts that are authorized to access the Aruba 501
management tool. If this feature is disabled, anyone can access the management interface from any network
client by supplying the correct user name and password.
Procedure
1. Select Management > Management ACL to open the Management access control list configuration page.
