SYNOPSIS

        # Let SNMP::Info determine the correct subclass for you.
        my $l7 = new SNMP::Info(
                                 AutoSpecify => 1,
                                 Debug       => 1,
                                 DestHost    => 'myswitch',
                                 Community   => 'public',
                                 Version     => 1
                               )
           or die "Can't connect to DestHost.\n";

        my $class = $l7->class();
        print "SNMP::Info determined this device to fall under subclass : $class\n";

        # Let's get some basic Port information
        my $interfaces = $l7->interfaces();
        my $i_up       = $l7->i_up();
        my $i_speed    = $l7->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::Layer7::*   Please read all docs under SNMP::Info first.

       Provides abstraction to the configuration information obtainable from a Layer7 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 $l7 = new SNMP::Info::Layer7(...);

   Inherited Classes

   Required MIBs
       None

       See "Required MIBs" in SNMP::Info for its MIB requirements.

GLOBALS

       These are methods that return scalar value from SNMP

   Overrides
       $l7->model()
           Cross references $l7->id() with product IDs.

       $l7->vendor()
           Tries to discover the vendor by looking up the enterprise number in "sysObjectID".

   Global Methods imported from SNMP::Info
       See documentation in "GLOBALS" in SNMP::Info for details.

TABLE METHODS

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

   Overrides
       $l7->interfaces()
           Returns reference to the map between IID and physical Port.

       $l7->i_ignore()
           Returns reference to hash.  Increments value of IID if port is to be ignored.

           Ignores loopback, other, and cpu
