4400 This section describes the commands associated with the NAC/NAS network address resolution application. NAC/NAS is a client/server application running among Passport 4400 units. Like RSI/RSA, this application is involved in resolving network addresses of locally dialed phone numbers. Unlike RSI/RSA, which is used when a Passport 6400 is server, NAC/NAS is used when Passport 4400 units serve as both the client(s) and the server(s). See the following figure for a typical network architecture. Also unlike the RSI/RSA, with NAC/NAS you must reregister the telephone numbers attached to your Passport 4400 unit. See Configurator Procedure for Using the System Action Commands or CLI Procedure for Using the Action Commands as appropriate for details.
If your server is a Passport 6400 unit, network address resolution is implemented, as shown, in RSI/RSA.

Note: You may have both NAC and RSI servers specified in integrated 4400/6400 networks. |
You may use one of two procedures to configure NAC/NAS on your Passport 4400 unit:
The figure below shows a simplified block diagram for NAC/NAS resolution.
