Obtaining and Recording Parameters Required by the JUNOS::Device Object

The JUNOS::Device object takes the following required parameters, specified as keys in a Perl hash:

• The access protocol to use when communicating with the JUNOScript server (key name: access). For a list of the acceptable values, see Supported Access Protocols. Before the application runs, satisfy the protocol-specific prerequisites described in Prerequisites for Establishing a Connection.
• The name of the routing platform to which to connect (key name: hostname). For best results, specify either a fully qualified hostname or an IP address.
• The username under which to establish the connection to the JUNOScript server and issue requests (key name: login). The username must already exist on the specified routing platform and have the permission bits necessary for making the requests invoked by the application.
• The password for the username (key name: password).

The sample scripts record the parameters in a Perl hash called %deviceinfo, declared as follows:

     my %deviceinfo = (
        access => $access,
        login => $login,
        password => $password,
        hostname => $hostname,
     );

The sample scripts obtain the parameters from options entered on the command line by a user. Your application can also obtain values for the parameters from a file or database, or you can hardcode one or more of the parameters into the application code if they are constant.
