GLOBALS

       These are methods that return scalar value from SNMP

       $juniper->vendor()
           Returns 'juniper'

       $juniper->os()
           Returns 'junos'

       $juniper->layers()
           Checks forwarding table for Layer 2 support since some routers with switches do not
           report layers properly.

       $juniper->os_ver()
           Returns the software version extracted first from "sysDescr" or "lldpLocSysDesc" if
           not available in "sysDescr".

       $juniper->model()
           Returns the model from "sysObjectID", with "jnxProductName" removed from the
           beginning.

       $juniper->serial()
           Returns serial number

           ("jnxBoxSerialNo.0")

       $juniper->mac()
           Returns the MAC address used by this bridge when it must be referred to in a unique
           fashion.

           ("dot1dBaseBridgeAddress")

       $juniper->box_descr()
           The name, model, or detailed description of the device.

           ("jnxBoxDescr.0")

TABLE METHODS

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

       $juniper->qb_fdb_index()
           Returns reference to hash: key = VLAN ID, value = FDB ID.

       $juniper->v_index()
           ("jnxExVlanTag")

       $juniper->v_name()
           ("jnxExVlanName")

       $juniper->v_type()
           ("jnxExVlanType")

       $juniper->i_trunk()
           ("jnxExVlanPortAccessMode")

       $juniper->i_vlan()
           Returns a mapping between "ifIndex" and the PVID or default VLAN.

   Pseudo ENTITY-MIB information
       These methods emulate ENTITY-MIB Physical Table methods using JUNIPER-MIB and JUNIPER-
       VIRTUALCHASSIS-MIB.

       $juniper->e_index()
           Returns reference to hash.  Key: IID, Value: Integer, Indices are combined into a
           eight digit integer, each index is two digits padded with leading zero if required.

       $juniper->e_class()
           Returns reference to hash.  Key: IID, Value: General hardware type.

       $juniper->e_descr()
           Returns reference to hash.  Key: IID, Value: Human friendly name

       $juniper->e_hwver()
           Returns reference to hash.  Key: IID, Value: Hardware version

       $juniper->e_vendor()
           Returns reference to hash.  Key: IID, Value: juniper

       $juniper->e_serial()
           Returns reference to hash.  Key: IID, Value: Serial number

       $juniper->e_pos()
           Returns reference to hash.  Key: IID, Value: The relative position among all entities
           sharing the same parent.

       $juniper->e_type()
           Returns reference to hash.  Key: IID, Value: Type of component/sub-component as
           defined in JUNIPER-CHASSIS-DEFINES-MIB.

       $juniper->e_parent()
           Returns reference to hash.  Key: IID, Value: The value of e_index() for the entity
           which 'contains' this entity.  A value of zero indicates   this entity is not
           contained in any other entity.

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