—Includes functions for controlling terminal modes, for example
Term::ReadKey
suppressing onscreen echo of a typed string such as a password.
If the application uses constants, declare their values at this point. For example, the
sample script includes the following statements to declare constants
diagnose_bgp.pl
for formatting output:
use constant OUTPUT_FORMAT => "%-20s%-8s%-8s%-11s%-14s%s\n";
use constant OUTPUT_TITLE =>
"\n=============== BGP PROBLEM SUMMARY ===============\n\n";
use constant OUTPUT_ENDING =>
"\n===================================================\n\n";
The load_configuration.pl script includes the following statements to declare constants
for reporting return codes and the status of the configuration database:
use constant REPORT_SUCCESS => 1;
use constant REPORT_FAILURE => 0;
use constant STATE_CONNECTED => 1;
use constant STATE_LOCKED => 2;
use constant STATE_CONFIG_LOADED => 3;

Satisfying Protocol Prerequisites

The Junos XML protocol server supports several access protocols, listed in "Supported
Access Protocols" on page 27. For each connection to the Junos XML protocol server on
a device, the application must specify the protocol it is using. Using SSH or Secure Sockets
Layer (SSL) is recommended because they provide greater security by encrypting all
information before transmission across the network.
Before your application can run, you must satisfy the prerequisites for the protocol it
uses. For some protocols this involves activating configuration statements on the device,
creating encryption keys, or installing additional software on the device running Junos
OS or the machine where the application runs. For instructions, see "Prerequisites for
Establishing a Connection" on page 27.

Group Requests

Establishing a connection to the Junos XML protocol server on a device is one of the more
time- and resource-intensive functions performed by an application. If the application
sends multiple requests to a routing platform, it makes sense to send all of them within
the context of one connection. If your application sends the same requests to multiple
devices, you can structure the script to iterate through either the set of devices or the set
