SYNOPSIS

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

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

DESCRIPTION

       Provides abstraction to the configuration information obtainable from a HP ProCurve Switch
       via SNMP.

       Note:  Some HP Switches will connect via SNMP version 1, but a lot of config data will not
       be available.  Make sure you try and connect with Version 2 first, and then fail back to
       version 1.

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

        my $hp = new SNMP::Info::Layer2::HP4000(...);

Change Log

       Version 0.4 - Removed ENTITY-MIB e_*() methods to separate sub-class - SNMP::Info::Entity

GLOBALS

       These are methods that return scalar value from SNMP

       $hp->cpu()
           Returns CPU Utilization in percentage.

       $hp->log()
           Returns all the log entries from the switch's log that are not Link up or down
           messages.

       $hp->mem_free()
           Returns bytes of free memory

       $hp->mem_total()
           Return bytes of total memory

       $hp->mem_used()
           Returns bytes of used memory

       $hp->model()
           Returns the model number of the HP Switch.  Will translate between the HP Part number
           and the common model number with this map :

            %MODEL_MAP = (
                           'J4093A' => '2424M',
                           'J4110A' => '8000M',
                           'J4120A' => '1600M',
                           'J4121A' => '4000M',
                           'J4122A' => '2400M',
                           'J4122B' => '2424M',
                           );

       $hp->os()
           Returns hp

       $hp->os_bin()
           "hpSwitchRomVersion.0"

       $hp->os_ver()
           Tries to use os_version() and if that fails will try and cull the version from the
           description field.

       $hp->os_version()
           "hpSwitchOsVersion.0"

       $hp->serial()
           Returns serial number if available through SNMP

       $hp->slots()
           Returns number of entries in $hp->e_name that have 'slot' in them.

       $hp->vendor()
           hp

       $hp->fan()
           Returns fan status

       $hp->ps1_status()
           Power supply 1 status

       $hp->ps2_status()
           Power supply 2 status

TABLE METHODS

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

   Overrides
       $hp->interfaces()
           Uses $hp->i_description()

       $hp->i_duplex()
           Returns reference to map of IIDs to current link duplex.

       $hp->i_duplex_admin()
           Returns reference to hash of IIDs to admin duplex setting.

       $hp->vendor_i_type()
           Returns reference to hash of IIDs to HP specific port type ("hpSwitchPortType").

       $hp->i_name()
           Crosses i_name() with $hp->e_name() using $hp->e_port() and i_alias()

       $hp->i_vlan()
           Returns a mapping between "ifIndex" and the PVID (default VLAN) or untagged port when
           using HP-VLAN.

       $hp->i_vlan_membership()
           Returns reference to hash of arrays: key = "ifIndex", value = array of VLAN IDs.
           These are the VLANs which are members of the egress list for the port.  It is the
           union of tagged, untagged, and auto ports.

             Example:
             my $interfaces = $hp->interfaces();
             my $vlans      = $hp->i_vlan_membership();

             foreach my $iid (sort keys %$interfaces) {
               my $port = $interfaces->{$iid};
               my $vlan = join(',', sort(@{$vlans->{$iid}}));
               print "Port: $port VLAN: $vlan\n";
             }

       $hp->v_index()
           Returns VLAN IDs

       $hp->v_name()
           Returns VLAN names

       $hp->bp_index()
           Returns reference to hash of bridge port table entries map back to interface
           identifier (iid)

           Returns ("ifIndex") for both key and value for 1600, 2424, 4000, and 8000 models since
           they seem to have problems with BRIDGE-MIB

SET METHODS

       These are methods that provide SNMP set functionality for overridden methods or provide a
       simpler interface to complex set operations.  See "SETTING DATA VIA SNMP" in SNMP::Info
       for general information on set operations.
