Subclass for Juniper Devices running JUNOS

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

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

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")

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

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

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.

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?
