NAME
    Devel::REPL::Plugin::NAS - Add Perl to your network devices' command
    line interfaces

VERSION
    This document refers to version 0.0001_01 of Devel::REPL::Plugin::NAS

WARNING
    This is an *ALPHA RELEASE*. I'd really appreciate any bug reports; you
    can use the CPAN RT bug tracking system, or email me directly at the
    address at the bottom of this page.

    You probably also want to download the latest "Devel::REPL" code from
    its subversion repository, as it contains many updates to the version on
    CPAN.

PURPOSE
    Whilst running an automated interactive session on a network device
    (e.g. a router) using Net::Appliance::Session, the device may throw an
    error. You can be dropped into a 'shell' on the device, for manual
    debugging, but the shell also has Perl bells and whistles.

    Alternatively, if used standalone, this module makes it seem like your
    network device manufacturer embedded Perl in their device's CLI. That's
    pretty cool.

SYNOPSIS
     my $repl = Devel::REPL->new;
     $repl->load_plugin('NAS');
     $repl->run;
 
    You're now at a Devel::REPL shell.

     re.pl:001:0> 3+3
     6
 
     re.pl:002:0> #nas_connect hostname.example username password
     $Net_Appliance_Session1 = Net::Appliance::Session=GLOB(0x92165ac);
 
    You're now conected via SSH to the device and at its CLI.

     Fa1/0/15  OWL visitor        notconnect   97           auto   auto 10/100BaseTX
 
     TEST_3750# conf t
     Enter configuration commands, one per line.  End with CNTL/Z.

     TEST_3750(config)# exit
 
    Run a one-off perl command:

     TEST_3750# #perl 3+6
     9

    Switch to Perl mode:

     TEST_3750# #nas_perl
     Switched into Perl mode.
     re.pl:008:0> 3+9
     12

    Run a one-off command on the device:

     re.pl:009:0> #nas show int status | incl 14
     Fa1/0/14  OWL VPN            notconnect   98           auto   auto 10/100BaseTX

    Use a Quoted Command operator to run device comands from within Perl
    code:

     re.pl:010:0> my @output = qc{ show int status };

    Switch back to device command mode:

     re.pl:011:0> #nas_cli
     Switched into NAS CLI mode.
     TEST_3750# 

    Press "control+d" to cleanly disconnect, from Perl or NAS CLI mode.

    Net::Appliance::Session
