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,

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 5500 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
(Portal Page Redirect) and/or
before
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 5500 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.
