SYNOPSIS

13        # Let SNMP::Info determine the correct subclass for you.
14        my $l1 = new SNMP::Info(
15                                 AutoSpecify => 1,

23        my $class = $l1->class();
24        print "SNMP::Info determined this device to fall under subclass : $class\n";
25
26        # Let's get some basic Port information
27        my $interfaces = $l1->interfaces();
28        my $i_up       = $l1->i_up();

DESCRIPTION

39       This class is usually used as a superclass for more specific device
40       classes listed under SNMP::Info::Layer1::*   Please read all docs under
41       SNMP::Info first.
42
43       Provides abstraction to the configuration information obtainable from a
44       Layer1 device through SNMP.  Information is stored in a number of MIBs.
45
46       For speed or debugging purposes you can call the subclass directly, but
47       not after determining a more specific class using the method above.
