DESCRIPTION
Subclass for Juniper Devices running JUNOS

  Inherited Classes

SNMP::Info::Layer3

  Required MIBs

JUNIPER-VLAN-MIB dated "200901090000Z" or later.
JUNIPER-CHASSIS-DEFINES-MIB
JUNIPER-MIB
JUNIPER-VIRTUALCHASSIS-MIB
JUNIPER-L2ALD-MIB

  Inherited Classes' MIBs
See "Required MIBs" in SNMP::Info::Layer3 for its own MIB requirements.

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")

$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")

$juniper->version()
    ("jnxVirtualChassisMemberSWVersion")

$juniper->vc_model()
    ("jnxVirtualChassisMemberModel")

See documentation in "GLOBALS" in SNMP::Info::Layer3 for details.

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 = FDB ID, value = VLAN ID.

$juniper->v_index()
    Returns ("jnxL2aldVlanTag") or ("jnxExVlanTag") depending upon switch software version

$juniper->v_name()
    Returns ("jnxL2aldVlanName") or ("jnxExVlanName") depending upon switch software version

$juniper->v_type()
    Returns ("jnxL2aldVlanType") or ("jnxExVlanType") depending upon switch software version

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

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

$juniper->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.

$juniper->i_vlan_membership_untagged()
    Returns reference to hash of arrays: key = "ifIndex", value = array of VLAN IDs. These are the VLANs which are members of the untagged egress list for the port.

$juniper->peth_port_ifindex()
    Returns reference to a hash: key= PowerEthernet MIB interface number, value = "ifIndex". As Juniper does not provide a mapping function, this does it manually. For example, ge-0/0/1 registers as PowerEthernet interface '1.2'

  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?

    ("entPhysicalFRU")
