SNMP::Info::Entity - SNMP Interface to data stored in ENTITY-MIB. RFC 2737

       Max Baker

ENTITY-MIB is used by Layer 2 devices from Brocade, Cisco, HP, and more.

       See RFC 2737 for full details.

       Create or use a device subclass that inherit this class.  Do not use directly.

       For debugging purposes you can call this class directly as you would SNMP::Info

        my $entity = new SNMP::Info::Entity (...);

   InheritedClasses
       none.

   RequiredMIBsENTITY-MIB

       none.

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

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

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

       $entity->entity_derived_serial()
           Tries  to  determine  the device serial number from the ENTITY-MIB. Only considers serial numbers for
           entries without a parent, or if they are of type chassis. Looks at  "entPhysicalSerialNum"  and  then
           "entPhysicalDescr" for serial number.

       $entity->entity_derived_os_ver()
           Tries  to  determine  the  device  OS  version from the ENTITY-MIB. Only considers serial numbers for
           entries without a parent, or if they are of type chassis. Looks at "entPhysicalSoftwareRev"  for  the
           version.

   EntityTable
       $entity->e_index()
           Index

           ("entPhysicalIndex")

       $entity->e_alias()
           Human entered, not usually used.

           ("entPhysicalAlias")

       $entity->e_class()
           Stack, Module, Container, Port ...

           ("entPhysicalClass")

       $entity->e_descr()
           Human Friendly

           ("entPhysicalClass")

       $entity->e_fwver()
           ("entPhysicalFirmwareRev")

       $entity->e_fru()
           BOOLEAN. Is a Field Replaceable unit?

           ("entPhysicalFRU")

       $entity->e_hwver()
           ("entPhysicalHardwareRev")

       $entity->e_id()
           This is human entered and not normally used.

           ("entPhysicalAssetID")

       $entity->e_map()
           See MIB.

           ("entAliasMappingIdentifier")

       $entity->e_model()
           Model Name of Entity.

           ("entPhysicalModelName")

       $entity->e_name()
           More computer friendly name of entity.  Parse me.

           ("entPhysicalName")

       $entity->e_parent()
           0 if root.

           ("entPhysicalContainedIn")

       $entity->e_port()
           Maps Entity Table entries to the Interface Table ("IfTable") using $entity->e_map()

       $entity->e_pos()
           The relative position among all entities sharing the same parent.

           ("entPhysicalParentRelPos")

       $entity->e_serial()
           ("entPhysicalSerialNum")

       $entity->e_swver()
           ("entPhysicalSoftwareRev")

       $entity->e_type()
           This is an OID, which gets munged into the object name if the right MIB is loaded.

           ("entPhysicalVendorType")

       $entity->e_vendor()
           Vendor of Module.

           ("entPhysicalMfgName")
