SNMP::Info::CDP - Perl5 Interface to Cisco Discovery Protocol (CDP) using SNMP
=head1 DESCRIPTION
SNMP::Info::CDP is a subclass of SNMP::Info that provides an object oriented
interface to CDP information through SNMP.
CDP is a Layer 2 protocol that supplies topology information of devices that also speak CDP,
mostly switches and routers. CDP is implemented in Cisco and some HP devices.
Normally you do not use this module directly, but from inside SNMP::Info

SNMP::Info::CDP is a subclass of SNMP::Info that provides an object oriented
interface to CDP information through SNMP.
CDP is a Layer 2 protocol that supplies topology information of devices that also speak CDP,
mostly switches and routers. CDP is implemented in Cisco and some HP devices.
Create or use a device subclass that inherits this class. Do not use directly.
Each device implements a subset of the global and cache entries.
Check the return value to see if that data is held by the device.

This class is usually used as a superclass for more specific device classes listed under
SNMP::Info::Layer1::* Please read all docs under SNMP::Info first.
Provides abstraction to the configuration information obtainable from a
Layer1 device through SNMP. Information is stored in a number of MIBs.
For speed or debugging purposes you can call the subclass directly, but not after determining
a more specific class using the method above.
