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

GLOBALS
These are methods that return scalar value from SNMP

$juniper->vendor()
    Returns 'juniper'

$juniper->os()
    Returns 'junos'

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

    ("dot1dBaseBridgeAddress")

$juniper->hasCDP()
    Returns whether LLDP is enabled.

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

  Global Methods imported from SNMP::Info::LLDP
See documentation in "GLOBALS" in SNMP::Info::LLDP for details.

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

$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.

$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.

  Topology information
These methods return Link Layer Discovery Protocol (LLDP) information. See documentation in "TABLE METHODS" in SNMP::Info::LLDP for details.

$juniper->c_id()
    Returns "lldp_id"

$juniper->c_if()
    Returns "lldp_if"

$juniper->c_ip()
    Returns "lldp_ip"

$juniper->c_platform()
    Returns "lldp_rem_sysdesc"

$juniper->c_port()
    Returns "lldp_port"

  Forwarding Table ("dot1dTpFdbEntry")

$juniper->fw_mac()
    Returns reference to hash of forwarding table MAC Addresses

    ("dot1dTpFdbAddress")

$juniper->fw_port()
    Returns reference to hash of forwarding table entries port interface identifier (iid)

    ("dot1dTpFdbPort")

  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")
