SYNOPSIS

13        # Let SNMP::Info determine the correct subclass for you.
14        my $l2 = new SNMP::Info(
15                                 AutoSpecify => 1,
16                                 Debug       => 1,
17                                 DestHost    => 'myswitch',
18                                 Community   => 'public',
19                                 Version     => 2
20                               )
21           or die "Can't connect to DestHost.\n";
22
23        my $class      = $l2->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 = $l2->interfaces();
28        my $i_up       = $l2->i_up();
29        my $i_speed    = $l2->i_speed();

32           my $up    = $i_up->{$iid};
33           my $speed = $i_speed->{$iid}
34           print "Port $port is $up. Port runs at $speed.\n";

DESCRIPTION

38       This class is usually used as a superclass for more specific device
39       classes listed under SNMP::Info::Layer2::*   Please read all docs under
40       SNMP::Info first.
41
42       Provides abstraction to the configuration information obtainable from a
43       Layer2 device through SNMP.  Information is stored in a number of MIBs.
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.

61

GLOBALS

63       These are methods that return scalar value from SNMP
64
65   Overrides
66       $l2->model()
67           Cross references $l2->id() with product IDs in the Cisco MIBs.
68
69           For HP devices, removes 'hpswitch' from the name
70
71           For Cisco devices, removes c<'sysid'> from the name
72
73       $l2->vendor()
74           Tries to discover the vendor from $l2->model() and
75           $l2->description()
76
77       $l2->serial()
78           Returns a serial number if found from ENTITY-MIB and OLD-CISCO-...
79           MIB.

96
97   Overrides
98       $l2->interfaces()
99           Creates a map between the interface identifier (iid) and the
100           physical port name.
101
102           Defaults to "ifDescr" but checks and overrides with "ifName"
