Setting the National Personality

Each public data network, such as GTE's Telenet or DDN's Defense Data Network, has its own standard con®guration. The termNational Personality speci®es a group of variables used to de®ne a public data network's characteristics. The con®guration information in the National Personality provides the router with control information for packets being transferred over the link. The National Personality option de®nes 27 default parameters for each public data network.

To view the con®guration values that are in your X.25 National Personality, execute the X.25 con®gurationlist detailed command. Con®gure each public data network connected to the router by executing the X.25 con®gurationnational-personality set command.

The National Personality is a generalized template for network con®guration. If necessary, you can individually con®gure each frame and packet layer parameter.
