=head1 NAME

SNMP::Info::Layer3::Contivity - SNMP Interface to Avaya/Nortel VPN Routers
(formerly Contivity Extranet Switches).

=head1 SYNOPSIS

 # Let SNMP::Info determine the correct subclass for you. 
 my $contivity = new SNMP::Info(
                          AutoSpecify => 1,
                          Debug       => 1,
                          DestHost    => 'myswitch',
                          Community   => 'public',
                          Version     => 2
                        ) 
    or die "Can't connect to DestHost.\n";

 my $class = $contivity->class();
 print "SNMP::Info determined this device to fall under subclass : $class\n";

=head1 DESCRIPTION

Abstraction subclass for Avaya/Nortel VPN Routers (formerly Contivity
Extranet Switch).  

For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above. 

 my $contivity = new SNMP::Info::Layer3::Contivity(...);

=head1 GLOBALS

These are methods that return scalar value from SNMP

=over

=item $contivity->vendor()

Returns 'avaya'

=item $contivity->model()

Returns the chassis name.

(C<entPhysicalModelName.1>)

=item $contivity->os()

Returns C<'CES'>
