=head1 NAME
SNMP::Info::Layer3::Contivity - SNMP Interface to Nortel VPN Routers (Contivity
Extranet Switches).
=head1 AUTHOR
Eric Miller
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $contivity = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly on to SNMP::Session
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 Nortel VPN Routers (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 'Nortel'
=item $contivity->model()
Returns the chassis name.
(B<entPhysicalModelName.1>)
=item $contivity->os()
Returns 'CES'

(B<entPhysicalSerialNum.1>)
=item $contivity->mac()
Returns the MAC address of the first Ethernet Interface.
=back
=head2 Overrides

=item $contivity->layers()
Returns 00000100. Contivity does not support bridge MIB, so override reported
layers.
