=head1 NAME
SNMP::Info::Layer3::AlteonAD - Perl5 Interface to Nortel Networks' Alteon Ace
Director Series Layer 2-7 Switches.
=head1 AUTHOR
Eric Miller (C<eric@jeneric.org>)
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $alteon = 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 = $alteon->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Abstraction subclass for Layer 2-7 load balancing switches running Nortel Networks'
Alteon Web OS Traffic Control Software.
For speed or debugging purposes you can call the subclass directly, but not after
determining a more specific class using the method above.

to a hash.
=head2 Overrides
=over
=item $alteon->interfaces()
Returns reference to the map between IID and physical port.
Utilizes description for network interfaces. Ports are determined by
formula (ifIndex mod 256).
=item $alteon->i_duplex()
Returns reference to hash. Maps port operational duplexes to IIDs.
=item $alteon->i_duplex_admin()
Returns reference to hash. Maps port admin duplexes to IIDs.
=item $alteon->i_vlan()
Returns reference to hash. Maps port VLAN ID to IIDs.
=item $alteon->i_name()
Maps (B<agPortCurCfgPortName>) to port and returns the human set port name if exists.
=item $alteon->bp_index()
Returns a mapping between ifIndex and the Bridge Table.

Returns reference to hash. Maps ARP table entries to MAC addresses.
(B<ipNetToMediaPhysAddress>)
=item $alteon->at_netaddr()
Returns reference to hash. Maps ARP table entries to IPs
