=head1 DESCRIPTION
|
|
|
|
This class is usually used as a superclass for more specific device classes
|
|
listed under SNMP::Info::Layer3::* Please read all docs under SNMP::Info
|
|
first.
|
|
|
|
Provides generic methods for accessing SNMP data for Layer 3 network devices.
|
|
Includes support for Layer2+3 devices.
|
|
|
|
For speed or debugging purposes you can call the subclass directly, but not
|
|
after determining a more specific class using the method above.
