NAME

       SNMP::Info::Layer1 - SNMP Interface to network devices serving Layer1 only.

AUTHOR

SYNOPSIS

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

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

	# 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.
";
	}

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(...);

   Required MIBs
       SNMP-REPEATER-MIB

       MIBs required for "Required MIBs" in SNMP::Info

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

       SNMP-REPEATER-MIB needs to be extracted from ftp://ftp.cisco.com/pub/mibs/v1/v1.tar.gz

GLOBALS

       These are methods that return scalar value from SNMP

       $l1->ports_managed()
	   Gets the number of ports under the interface mib

	   ("ifNumber")

   Overrides
       $l1->model()
	   Cross references $l1->id() with product IDs.

	   For HP devices, removes 'hpswitch' from the name

	   For Cisco devices, removes 'sysid' from the name

       $l1->vendor()
	   Tries to discover the vendor from $l1->model() and $l1->vendor()

       $l1->ports()
	   Adds the values from rptr_ports() and ports_managed()

       $l1->slots()
	   Number of 'groups' in the Repeater MIB

	   ("rptrGroupCapacity")

       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
       $l1->interfaces()
	   Returns reference to the map between IID and physical Port.

       $l1->i_up()
	   Returns reference to map of IIDs to link status.

       $l1->i_up_admin()
	   Returns reference to map of IIDs to administrative link status.

   Repeater MIB
       $l1->rptr_ports()
	   Number of ports in each group.

	   ("rptrGroupPortCapacity")

       $l1->rptr_port()
	   Port number in Group

	   ("rptrPortIndex")

       $l1->rptr_slot()
	   Group (slot) Number for given port.

	   ("rptrPortGroupIndex")

       $l1->rptr_up_admin()
	   ("rptrPortAdminStatus")

       $l1->rptr_up()
	   ("rptrPortOperStatus")

       $l1->rptr_last_src()
	   ("rptrAddrTrackNewLastSrcAddress")
