DESCRIPTION

38       This class is usually used as a superclass for more specific device
39       classes listed under SNMP::Info::Layer3::*   Please read all docs under
40       SNMP::Info first.
41
42       Provides generic methods for accessing SNMP data for Layer 3 network
43       devices.  Includes support for Layer2+3 devices.
44
45       For speed or debugging purposes you can call the subclass directly, but
46       not after determining a more specific class using the method above.

TABLE METHODS

155       These are methods that return tables of information in the form of a
156       reference to a hash.

167           Returns reference to hash of iid to human set name.

172           Returns reference to hash of iid to current link duplex setting.
173
174           Maps $l3->el_index() to $l3->el_duplex, then culls out full,half,
175           or auto and sets the map to that value.
