22 Introduction
MAC Filtering
MAC Filtering enhances Nomadix' access control technology by allowing system
administrators to block malicious users based on their MAC address. Up to 50 MAC
addresses can be blocked at any one time. See also, “Session Rate Limiting (SRL)” on
page 26 .
Multi-Level Administration Support
The NSE allows you to define 2 concurrent access levels to differentiate between
managers and operators, where managers are permitted read/write access and
operators are restricted to read access only.
Once the logins have been assigned, managers have the ability to perform all write
commands (Submit, Reset, Reboot, Add, Delete, etc.), but operators cannot change
any system settings. When Administration Concurrency is enabled, one manager and
three operators can access the AG-2000w platform at any one time.
NTP Support
The NSE supports Network Time Protocol (NTP), an Internet standard protocol that
assures accurate synchronization (to the millisecond) of computer clock times in a
network of computers. NTP synchronizes the client’s clock to the U.S. Naval
Observatory master clocks. Running as a continuous background client program on a
computer, NTP sends periodic time requests to servers, obtaining server time stamps
and using them to adjust the client's clock.
Portal Page Redirect
The NSE contains a comprehensive HTTP page redirection logic that allows for a
page redirect
before
(Portal Page Redirect) and/or
after
the authentication process
(Home Page Redirect). As part of the Portal Page Redirect feature, the NSE can send
a defined set of parameters to the portal page redirection logic that allows an External
Web Server to perform a redirection based on:
‹
AG-2000w ID and IP Address
‹
Origin Server
‹
Port Location
‹
Subscriber MAC address
‹
Externally hosted RADIUS login failure page
This means that the network administrator can now perform location-specific service
branding (for example, an airport lounge) from a centralized Web server.
