=head1 NAME
SNMP::Info::Layer3::C6500 - SNMP Interface to Cisco Catalyst 6500 Layer 2/3
Switches running IOS and/or CatOS
=head1 AUTHOR
Max Baker
=head1 SYNOPSIS
# Let SNMP::Info determine the correct subclass for you.
my $c6500 = 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 = $c6500->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";
=head1 DESCRIPTION
Abstraction subclass for Cisco Catalyst 6500 Layer 2/3 Switches.
These devices run IOS but have some of the same characteristics as the
Catalyst WS-C family (5xxx). 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.
my $c6500 = new SNMP::Info::Layer3::C6500(...);

=head1 TABLE METHODS
These are methods that return tables of information in the form of a reference
to a hash.
=head2 Overrides
=over
=item $c6500->i_duplex()
Returns reference to hash of iid to current link duplex setting.
Newer software versions return duplex based upon the result of
$c6500->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 $c6500->i_duplex_admin()
Returns reference to hash of iid to administrative duplex setting.
Newer software versions return duplex based upon the result of
$c6500->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 $c6500->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 $c6500->p_port() with $c6500->p_duplex() to utilize port C<ifIndex>.
Example:
my %if_map = reverse %{$c6500->interfaces()};
$c6500->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'})
or die "Couldn't change port duplex. ",$c6500->error(1);
=item $c6500->set_i_speed_admin(speed, ifIndex)
Sets port speed, must be supplied with speed and port C<ifIndex>.
Speed choices are '10', '100', '1000'.
Crosses $c6500->p_port() with $c6500->p_speed() to utilize port C<ifIndex>.
