Configuring the X.25 Services
When you configure Passport 4400 units for X.25 services, make sure that your configurations meet the following requirements:
- One end (Passport unit) must be the master for each X.25 connection. The master end initiates the X.25 connection.
- The master end must be configured with the PANL DNA of the destination end (the remote Passport unit).
- Each destination end (Passport unit) must be configured to provide X.25 services across the PANL or DLCI connection.
To configure Passport units for X.25 services, use either the Configurator or the CLI.
