=head1 NAME
SNMP::Info::Layer3::N1600 - SNMP Interface to Avaya/Nortel 16XX Network
Devices
=head1 AUTHOR
Eric Miller
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $n1600 = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
DestHost => 'myswitch',
Community => 'public',
Version => 1
)
or die "Can't connect to DestHost.\n";
my $class = $n1600->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Provides abstraction to the configuration information obtainable from an
Avaya/Nortel N16XX device through SNMP.
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.
my $n1600 = new SNMP::Info::Layer3::N1600(...);
=head2 Inherited Classes
=over
=item SNMP::Info::Layer3
=item SNMP::Info::SONMP
=back
=head2 Required MIBs
=over
=item F<SWL2MGMT-MIB>
=item F<RAPID-CITY>
=item Inherited Classes' MIBs
See classes listed above for their required MIBs.
=back
=head1 GLOBALS
These are methods that return scalar value from SNMP
=over
=item $n1600->bulkwalk_no
Return C<1>. Bulkwalk is currently turned off for this class.
=item $n1600->model()
Returns model type. Checks $n1600->id() against the
F<RAPID-CITY-MIB> and then parses out C<rcA>.
=item $n1600->vendor()
Returns 'avaya'
=item $n1600->os()
Returns 'passport'
=item $n1600->os_ver()
Returns os version extracted from C<sysDescr>.
=back
=head2 Overrides
=over
=item $n1600->index_factor()
Required by SNMP::Info::SONMP. Number representing the number of ports
reserved per slot within the device MIB.
Returns 64 since largest switch has 48 ports. Since these switches can
not stack, the only requirement to reserve more than the max number of ports.

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $n1600->interfaces()
Returns reference to hash of interface names to iids.
Places a 1 in front of index number. This is required for compatibility with
SNMP::Info::SONMP.
=item $n1600->i_duplex()
Returns reference to hash of interface operational link duplex status.
=item $n1600->i_duplex_admin()
Returns reference to hash of interface administrative link duplex status.
