NWA1121-NI User’s Guide

• You may only have one remote management session running at one time. The NWA1121-NI 

automatically disconnects a remote management session of lower priority when another remote 
management session of higher priority starts. The priorities for the different types of remote 
management sessions are as follows:

Telnet

HTTP

There is a default system management idle timeout of five minutes (three hundred seconds). The 
NWA1121-NI automatically logs you out if the management session remains idle for longer than 
this timeout period. The management session does not time out when a statistics screen is polling. 
You can change the timeout period in the SYSTEM screen.

A certificate contains the certificate owner’s identity and public key. Certificates provide a way to 
exchange public keys for use in authentication.

Certificates Example

In the figure above, the NWA1121-NI (Z) checks the identity of the notebook (A) using a certificate 
before granting access to the network.

The certification authority certificate that you can import to your NWA1121-NI should be in PFX 
PKCS#12 file format. This format referred to as the Personal Information Exchange Syntax 
Standard is comprised of a private key-public certificate pair that is further encrypted with a 
password. Before you import a certificate into the NWA1121-NI, you should verify that you have the 
correct certificate.

Key distribution is simple and very secure since you can freely distribute public keys and you never 
need to transmit private keys.

Use this screen to configure your NWA1121-NI via the World Wide Web (WWW) using a Web 
browser. This lets you specify which IP addresses or computers are able to communicate with and 
access the NWA1121-NI.
