=head1 NAME
SNMP::Info::Layer3::C3550 - SNMP Interface to Cisco Catalyst 3550 Layer 2/3
Switches running IOS
=head1 AUTHOR
Max Baker
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $c3550 = new SNMP::Info(
AutoSpecify => 1,
Debug => 1,
# These arguments are passed directly to SNMP::Session
DestHost => 'myswitch',
Community => 'public',
Version => 2
)
or die "Can't connect to DestHost.\n";
my $class = $c3550->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Abstraction subclass for Cisco Catalyst 3550 Layer 2/3 Switches.
These devices run IOS but have some of the same characteristics as the
Catalyst WS-C family (5xxx,6xxx). For example, forwarding tables are held in
VLANs, and extended interface information is gleaned from F<CISCO-SWITCH-MIB>.
For speed or debugging purposes you can call the subclass directly, but not
after determining a more specific class using the method above.

Returns 'cisco'

Will take the translated model number and try to format it better.
355048 -> 3550-48
355012G -> 3550-12G
=item $c3550->ports()
Tries to cull the number of ports from the model number.

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $c3550->i_duplex()
Returns reference to hash of iid to current link duplex setting.
Software version 12.1(22)EA1a or greater returns duplex based upon the
result of $c3550->el_duplex(). Otherwise it uses the result of
the call to CiscoStack::i_duplex().
See L<SNMP::Info::Etherlike> for el_duplex() method and
L<SNMP::Info::CiscoStack> for its i_duplex() method.
=item $c3550->i_duplex_admin()
Returns reference to hash of iid to administrative duplex setting.
Software version 12.1(22)EA1a or greater returns duplex based upon the
result of $c3550->p_duplex(). Otherwise it uses the result of
the call to CiscoStack::i_duplex().
See L<SNMP::Info::CiscoStack> for its i_duplex() and p_duplex() methods.
=item $c3550->set_i_duplex_admin(duplex, ifIndex)
Sets port duplex, must be supplied with duplex and port C<ifIndex>.
Speed choices are 'auto', 'half', 'full'.
Crosses $c3550->p_port() with $c3550->p_duplex() to utilize port C<ifIndex>.
Example:
my %if_map = reverse %{$c3550->interfaces()};
$c3550->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'})
or die "Couldn't change port duplex. ",$c3550->error(1);
