=head1 DESCRIPTION
|
|
|
|
SNMP::Info::EDP is a subclass of SNMP::Info that provides an object oriented
|
|
interface to EDP information through SNMP.
|
|
|
|
EDP is a Layer 2 protocol that allows a network device to advertise its
|
|
identity and capabilities on the local network providing topology information.
|
|
|
|
Create or use a device subclass that inherits this class. Do not use
|
|
directly.
|
|
|
|
=head2 Inherited Classes
