2/3 Switches running IOS
AUTHOR

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";
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
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 $c3550 = new SNMP::Info::Layer3::C3550(...);

GLOBALS
These are methods that return scalar value from SNMP
$c3550->vendor()
Returns 'cisco'
$c3550->model()
Will take the translated model number and try to format it better.
355048 -> 3550-48
355012G -> 3550-12G
$c3550->ports()
Tries to cull the number of ports from the model number.
$c3550->cisco_comm_indexing()
Returns 1. Use vlan indexing.
Topology information
Based upon the firmware version Cisco devices may support Link Layer
Discovery Protocol (LLDP) in addition to Cisco Discovery Protocol
(CDP). These methods will query both and return the combination of all
information. As a result, there may be identical topology information
returned from the two protocols causing duplicate entries. It is the
calling program's responsibility to identify any duplicate entries and
remove duplicates if necessary.
$c3550->hasCDP()
Returns true if the device is running either CDP or LLDP.

TABLE METHODS
These are methods that return tables of information in the form of a
reference to a hash.
$c3550->c_if()
Returns reference to hash. Key: iid Value: local device port
(interfaces)
$c3550->c_ip()
Returns reference to hash. Key: iid Value: remote IPv4 address
If multiple entries exist with the same local port, c_if(), with
the same IPv4 address, c_ip(), it may be a duplicate entry.
If multiple entries exist with the same local port, c_if(), with
different IPv4 addresses, c_ip(), there is either a non-CDP/LLDP
device in between two or more devices or multiple devices which are
not directly connected.
Use the data from the Layer2 Topology Table below to dig deeper.
$c3550->c_port()
Returns reference to hash. Key: iid Value: remote port (interfaces)
$c3550->c_id()
Returns reference to hash. Key: iid Value: string value used to
identify the chassis component associated with the remote system.
$c3550->c_platform()
Returns reference to hash. Key: iid Value: Remote Device Type
Overrides
$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 SNMP::Info::Etherlike for el_duplex() method and
SNMP::Info::CiscoStack for its i_duplex() method.
$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 SNMP::Info::CiscoStack for its i_duplex() and p_duplex()
methods.
$c3550->set_i_duplex_admin(duplex, ifIndex)
Sets port duplex, must be supplied with duplex and port "ifIndex".
Speed choices are 'auto', 'half', 'full'.
Crosses $c3550->p_port() with $c3550->p_duplex() to utilize port
"ifIndex".
Example:
my %if_map = reverse %{$c3550->interfaces()};
$c3550->set_i_duplex_admin('auto', $if_map{'FastEthernet0/1'})
or die "Couldn't change port duplex. ",$c3550->error(1);
