DESCRIPTION

       SNMP::Info::LLDP is a subclass of SNMP::Info that provides an object oriented interface to
       LLDP information through SNMP.

       LLDP is a Layer 2 protocol that allows a network device to advertise its identity and
       capabilities on the local network providing topology information.  The protocol is defined
       in the IEEE standard 802.1AB.

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

   Inherited Classes
       None.

   Required MIBs
       LLDP-MIB
       LLDP-EXT-DOT1-MIB
       LLDP-EXT-DOT3-MIB

GLOBAL METHODS

       These are methods that return scalar values from SNMP

       $lldp->hasLLDP()
           Is LLDP is active in this device?

           Note:  LLDP may be active, but nothing in "lldpRemoteSystemsData" Tables so the device
           would not return any useful topology information.

       $lldp->lldp_sysname()
           The string value used to identify the system name of the local system.  If the local
           agent supports IETF RFC 3418, "lldpLocSysName" object should have the same value of
           "sysName" object.

           Nulls are removed before the value is returned.

           ("lldpLocSysName")

       $lldp->lldp_sysdesc()
           The string value used to identify the system description of the local system.  If the
           local agent supports IETF RFC 3418, "lldpLocSysDesc" object should have the same value
           of "sysDesc" object.

           Nulls are removed before the value is returned.

           ("lldpLocSysDesc")

       $lldp->lldp_sys_cap()
           Returns which system capabilities are enabled on the local system.  Results are munged
           into an ascii binary string, LSB.  Each digit represents a bit from the table below:

           Bit 'other(0)' indicates that the system has capabilities other than those listed
           below.
           Bit 'repeater(1)' indicates that the system has repeater capability.
           Bit 'bridge(2)' indicates that the system has bridge capability.
           Bit 'wlanAccessPoint(3)' indicates that the system has WLAN access point capability.
           Bit 'router(4)' indicates that the system has router capability.
           Bit 'telephone(5)' indicates that the system has telephone capability.
           Bit 'docsisCableDevice(6)' indicates that the system has DOCSIS Cable Device
           capability (IETF RFC 2669 & 2670).
           Bit 'stationOnly(7)' indicates that the system has only station capability and nothing
           else."

TABLE METHODS

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

       $lldp->lldp_id()
           Returns the string value used to identify the chassis component  associated with the
           remote system.

           ("lldpRemChassisId")

       $lldp->lldp_if()
           Returns the mapping to the SNMP Interface Table.

       $lldp->lldp_ip()
           Returns remote IPv4 address.  Returns for all other address types, use lldp_addr if
           you want any return address type.

       $lldp->lldp_addr()
           Returns remote address.  Type may be any IANA Address Family Number.  Currently only
           returns IPv4 or MAC addresses.

       $lldp->lldp_port()
           Returns remote port ID

   LLDP Remote Table ("lldpRemTable")
       $lldp->lldp_rem_id_type()
           Returns the type of encoding used to identify the chassis associated with the remote
           system.

           ("lldpRemChassisIdSubtype")

       $lldp->lldp_rem_id()
           Returns the string value used to identify the chassis component  associated with the
           remote system.

           ("lldpRemChassisId")

       $lldp->lldp_rem_pid_type()
           Returns the type of port identifier encoding used in the associated "lldpRemPortId"
           object.

           ("lldpRemPortIdSubtype")

       $lldp->lldp_rem_pid()
           Returns the string value used to identify the port component associated with the
           remote system.

           ("lldpRemPortId")

       $lldp->lldp_rem_desc()
           Returns the string value used to identify the description of the given port associated
           with the remote system.

           Nulls are removed before the value is returned.

           ("lldpRemPortDesc")

       $lldp->lldp_rem_sysname()
           Returns the string value used to identify the system name of the remote system.

           Nulls are removed before the value is returned.

           ("lldpRemSysName")

       $lldp->lldp_rem_sysdesc()
           Returns the string value used to identify the system description of the remote system.

           Nulls are removed before the value is returned.

           ("lldpRemSysDesc")

       $lldp->lldp_rem_sys_cap()
           Returns which system capabilities are enabled on the local system.  Results are munged
           into an ascii binary string, LSB.  Each digit represents a bit from the table below:

           Bit 'other(0)' indicates that the system has capabilities other than those listed
           below.
