DESCRIPTION

41       SNMP::Info::LLDP is a subclass of SNMP::Info that provides an object
42       oriented interface to LLDP information through SNMP.
43
44       LLDP is a Layer 2 protocol that allows a network device to advertise
45       its identity and capabilities on the local network providing topology
46       information.  The protocol is defined in the IEEE standard 802.1AB.
47
48       Create or use a device subclass that inherits this class.  Do not use
49       directly.
50
51   Inherited Classes
52       None.
53
54   Required MIBs
55       LLDP-MIB
56       LLDP-EXT-MED-MIB
57       LLDP-EXT-DOT1-MIB
58       LLDP-EXT-DOT3-MIB

GLOBALS

61       These are methods that return scalar values from SNMP
62
63       $lldp->hasLLDP()
64           Is LLDP is active in this device?
65
66           Note:  LLDP may be active, but nothing in "lldpRemoteSystemsData"
67           Tables so the device would not return any useful topology
68           information.
69
70       $lldp->lldp_sysname()
71           The string value used to identify the system name of the local
72           system.  If the local agent supports IETF RFC 3418,
73           "lldpLocSysName" object should have the same value of "sysName"
74           object.
75
76           Nulls are removed before the value is returned.
77
78           ("lldpLocSysName")
79
80       $lldp->lldp_sysdesc()
81           The string value used to identify the system description of the
82           local system.  If the local agent supports IETF RFC 3418,
83           "lldpLocSysDesc" object should have the same value of "sysDesc"
84           object.
85
86           Nulls are removed before the value is returned.
87
88           ("lldpLocSysDesc")
89
90       $lldp->lldp_sys_cap()
91           Returns which system capabilities are enabled on the local system.
92           Results are munged into an ascii binary string, LSB.  Each digit
93           represents a bit from the table below:
94
95           Bit 'other(0)' indicates that the system has capabilities other
96           than those listed below.
97           Bit 'repeater(1)' indicates that the system has repeater
98           capability.
99           Bit 'bridge(2)' indicates that the system has bridge capability.
100           Bit 'wlanAccessPoint(3)' indicates that the system has WLAN access
101           point capability.
102           Bit 'router(4)' indicates that the system has router capability.
103           Bit 'telephone(5)' indicates that the system has telephone
104           capability.
105           Bit 'docsisCableDevice(6)' indicates that the system has DOCSIS
106           Cable Device capability (IETF RFC 2669 & 2670).
107           Bit 'stationOnly(7)' indicates that the system has only station
108           capability and nothing else."

TABLE METHODS

113       These are methods that return tables of information in the form of a
114       reference to a hash.
115
116       $lldp->lldp_id()
117           Returns the string value used to identify the chassis component
118           associated with the remote system.
119
120           ("lldpRemChassisId")
121
122       $lldp->lldp_if()
123           Returns the mapping to the SNMP Interface Table. Tries to cross
124           reference ("lldpLocPortDesc") with ("ifDescr") and ("ifAlias") to
125           get ("ifIndex"), if unable defaults to ("lldpRemLocalPortNum").
126
127       $lldp->lldp_ip()
128           Returns remote IPv4 address.  Returns for all other address types,
129           use lldp_addr if you want any return address type.
130
131       $lldp->lldp_ipv6()
132           Returns remote IPv6 address, if known.  Returns for all other
133           address types, use lldp_addr if you don't care about return address
134           type.
135
136       $lldp->lldp_mac()
137           Returns remote (management) MAC address, if known.  Returns for all
138           other address types, use lldp_addr if you don't care about return
139           address type.
140
141       $lldp->lldp_addr()
142           Returns remote address.  Type may be any IANA Address Family
143           Number.  Currently only returns IPv4, IPv6 or MAC addresses. If the
144           remote device returns more than one address type, this method will
145           give only one. Which one is returned is decided by chance, phase of
146           the moon and Perl hash ordering.
147
148           Use lldp_mac, lldp_ip or lldp_ipv6 if you want a specific address
149           type.
150
151       $lldp->lldp_port()
152           Returns remote port ID
153
154       $lldp->lldp_platform()
155           Tries to return something useful from "lldp_rem_sysdesc()" or
156           "lldp_rem_sysname()".
157
158       $lldp->lldp_cap()
159           Returns hash of arrays with each array containing the system
160           capabilities supported by the remote system.  Possible elements in
161           the array are enumerated from "LldpSystemCapabilitiesMap".
162
163       $lldp->lldp_media_cap()
164           Returns hash of arrays with each array containing the media
165           capabilities supported by the remote system.  Possible elements in
166           the array are enumerated from "LldpXMedCapabilities".
167

169       $lldp->lldp_rem_id_type()
170           Returns the type of encoding used to identify the chassis
171           associated with the remote system.
