NAME
       SNMP::Info::Layer2 - SNMP Interface to network devices serving Layer2
       only.

AUTHOR
       Max Baker

SYNOPSIS
	# Let SNMP::Info determine the correct subclass	for you.
	my $l2 = new SNMP::Info(
				 AutoSpecify =>	1,
				 Debug	     =>	1,
				 DestHost    =>	'myswitch',
				 Community   =>	'public',
				 Version     =>	2
			       )
	   or die "Can't connect to DestHost.\n";

	my $class      = $l2->class();
	print "SNMP::Info determined this device to fall under subclass	: $class\n";

	# Let's	get some basic Port information
	my $interfaces = $l2->interfaces();
	my $i_up       = $l2->i_up();
	my $i_speed    = $l2->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::Layer2::*   Please read	all docs under
       SNMP::Info first.

       Provides	abstraction to the configuration information obtainable	from a
       Layer2 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 $l2 = new SNMP::Info::Layer2(...);

   Inherited Classes
       SNMP::Info
       SNMP::Info::Bridge
       SNMP::Info::Entity
       SNMP::Info::LLDP

   Required MIBs
       Inherited Classes
	   MIBs	required by the	inherited classes listed above.

       MIBs can	be found in netdisco-mibs package.

GLOBALS
       These are methods that return scalar value from SNMP

   Overrides
       $l2->model()
	   Cross references $l2->id() with product IDs in the Cisco MIBs.

	   For HP devices, removes 'hpswitch' from the name

	   For Cisco devices, removes c<'sysid'> from the name

       $l2->vendor()
	   Tries to discover the vendor	from $l2->model() and
	   $l2->description()

       $l2->serial()
	   Returns a serial number if found from ENTITY-MIB and	OLD-CISCO-...
	   MIB.

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

   Globals imported from SNMP::Info::Bridge
       See documentation in "GLOBALS" in SNMP::Info::Bridge for	details.

   Globals imported from SNMP::Info::Entity
       See documentation in "GLOBALS" in SNMP::Info::Entity for	details.

   Globals imported from SNMP::Info::LLDP
       See documentation in "GLOBALS" in SNMP::Info::LLDP for details.

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

   Overrides
       $l2->interfaces()
	   Creates a map between the interface identifier (iid)	and the
	   physical port name.

	   Defaults to "ifDescr" but checks and	overrides with "ifName"
