SNMP::Info::Layer7 - SNMP Interface to network devices serving Layer7 only.

 # 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";
 }

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(...);

SNMP::Info

None
MIBs required for "Required MIBs" in SNMP::Info
See "Required MIBs" in SNMP::Info for its MIB requirements.

These are methods that return scalar value from SNMP

$l7->model()
Cross references $l7->id() with product IDs.
$l7->vendor()
Tries to discover the vendor by looking up the enterprise number in "sysObjectID".

See documentation in "GLOBALS" in SNMP::Info for details.

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

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

See documentation in "TABLE METHODS" in SNMP::Info for details.
