SYNOPSIS

# Let SNMP::Info determine the correct subclass for you. 
my $l1 = new SNMP::Info(
                         AutoSpecify => 1,
                         Debug       => 1,
                         # These arguments are passed directly on to SNMP::Session
                         DestHost    => 'myswitch',
                         Community   => 'public',
                         Version     => 1
                       ) 
   or die "Can't connect to DestHost.\n";

my $class      = $l1->class();
print "SNMP::Info determined this device to fall under subclass : $class\n";

# Let's get some basic Port information
my $interfaces = $l1->interfaces();
my $i_up       = $l1->i_up();
my $i_speed    = $l1->i_speed();

foreach my $iid (keys %$interfaces) {
   my $port  = $interfaces->{$iid};
   my $up    = $i_up->{$iid};
   my $speed = $i_speed->{$iid}
   print "Port $port is $up. Port runs at $speed.\n";
}

DESCRIPTION

This class is usually used as a superclass for more specific device classes listed under SNMP::Info::Layer1::* Please read all docs under SNMP::Info first.

Provides abstraction to the configuration information obtainable from a Layer1 device through SNMP. Information is stored in a number of MIBs.

For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above.

my $l1 = new SNMP::Info::Layer1(...);
