     lldpcli, lldpctl — control LLDP daemon


     lldpcli [-dv] [-u socket] [-f format] [-c file] [command ...]
     lldpctl [-dv] [-u socket] [-f format] [interfaces ...]


     The lldpcli program controls lldpd(8) daemon.

     When no command is specified, lldpcli will start an interactive shell which can be used to
     input arbitrary commands as if they were specified on the command line. This interactive
     shell should provide completion and history support.

     The options are as follows:

     -d      Enable more debugging information.

     -u socket
             Specify the Unix-domain socket used for communication with lldpd(8).

     -v      Show lldpcli version.

     -f format
             Choose the output format. Currently plain, xml, json and keyvalue formats are
             available. The default is plain.

     -c file
             Read the given configuration file. This option may be repeated several times. If a
             directory is provided, each file contained in it will be read  if ending by .conf.
             Order is alphabetical.

     When invoked as lldpctl, lldpcli will display detailed information about each neighbors on
     the specified interfaces or on all interfaces if none are specified. This command is mostly
     kept for backward compatibility with older versions.

     The following commands are supported by lldpcli.  When there is no ambiguity, the keywords
     can be abbreviated. For example, show neighbors ports eth0 summary and sh neigh p eth0 sum
     are the same command.


             Quit lldpcli.

       help [...]

             Display general help or help about a command. Also, you can get help using the
             completion or by pressing the ?  key. However, completion and inline help may be
             unavailable if lldpcli was compiled without readline support but help command is
             always available.

       show neighbors [ports ethX [,...]] [details | summary] [hidden]

             Display information about each neighbor known by lldpd(8) daemon. With summary, only
             a the name and the port description of each remote host will be displayed. On the
             other hand, with details, all available information will be displayed, giving a
             verbose view. When using hidden, also display remote ports hidden by the smart
             filter. When specifying one or several ports, the information displayed is limited
             to the given list of ports.

       show chassis [details | summary]

             Display information about local chassis. With summary, most details are skipped. On
             the other hand, with details, all available information will be displayed, giving a
             verbose view.

       watch [ports ethX [,...]] [details | summary] [hidden]

             Watch for any neighbor changes and report them as soon as they happen. When
             specifying ports, the changes are only reported when happening on the given ports.
             hidden, summary and details have the same meaning than previously described.

       show configuration

             Display global configuration of lldpd(8) daemon.

       show statistics [ports ethX [,...]] [summary]

             Report LLDP-related statistics, like the number of LLDPDU transmitted, received,
             discarded or unrecognized. When specifying ports, only the statistics from the given
             port are reported. With summary the statistics of each port is summed.


             Make lldpd(8) update its information and send new LLDP PDU on all interfaces.

       configure system hostname name

             Override system hostname with the provided value. By default, the system name is
             found from the resolved value of uname -n.

       unconfigure system hostname

             Do not override system hostname and restore the use of the node name.

       configure system description description

             Override chassis description with the provided value instead of using kernel name,
             node name, kernel version, build date and architecture.

       unconfigure system description

             Do not override chassis description and use a value computed from node name, kernel
             name, kernel version, build date and architecture instead.

       configure system platform description

             Override platform description with the provided value instead of using kernel name.
             This value is currently only used for CDP.

       unconfigure system platform

             Do not override platform description and use the kernel name. This option undoes the
             previous one.

       configure system interface pattern pattern

             Specify which interface to listen and send LLDPDU to. Without this option, lldpd
             will use all available physical interfaces. This option can use wildcards. Several
             interfaces can be specified separated by commas.  It is also possible to blacklist
             an interface by suffixing it with an exclamation mark. It is possible to whitelist
             an interface by suffixing it with two exclamation marks. A whitelisted interface
             beats a blacklisted interfaces which beats a simple matched interface. For example,
             with eth*,!eth1,!eth2 lldpd will only use interfaces starting by eth with the
             exception of eth1 and eth2.  While with *,!eth*,!!eth1 lldpcli will use all
             interfaces, except interfaces starting by eth with the exception of eth1.  When an
             exact match is found, it will circumvent some tests. For example, if eth0.12 is
             specified, it will be accepted even if this is a VLAN interface.

       unconfigure system interface pattern

             Remove any previously configured interface pattern and use all physical interafces.
             This option undoes the previous one.

       configure system interface description

             Some OS allows the user to set a description for an interface. Setting this option
             will enable lldpd to override this description with the name of the peer neighbor if
             one is found or with the number of neighbors found.

       unconfigure system interface descripton

             Do not update interface description with the name of the peer neighbor. This option
             undoes the previous one.

       configure system interface promiscuous

             Enable promiscuous mode on managed interfaces.

             When the interface is not managed any more (or when quitting lldpcli), the interface
             is left in promiscuous mode as it is difficult to know if someone else also put the
             interface in promiscuous mode.

             This option is known to be useful when the remote switch is a Cisco 2960 and the
             local network card features VLAN hardware acceleration. In this case, you may not
             receive LLDP frames from the remote switch. The most plausible explanation for this
             is the frame is tagged with some VLAN (usually VLAN 1) and your network card is
             filtering VLAN. This is not the only available solution to work-around this problem.
             If you are concerned about performance issues, you can also tag the VLAN 1 on each
             interface instead.

             Currently, this option has no effect on anything else than Linux. On other OS,
             either disable VLAN acceleration, tag VLAN 1 or enable promiscuous mode manually on
             the interface.

       unconfigure system interface promiscuous

             Do not set promiscuous mode on managed interfaces. This option does not disable
             promiscuous mode on interfaces already using this mode.

       configure system ip management pattern pattern

             Specify the management addresses of this system. As for interfaces (described
             above), this option can use wildcards and inversions.  Without this option, the
             first IPv4 and the first IPv6 are used. If an exact IP address is provided, it is
             used as a management address without any check. If only negative patterns are
             provided, only one IPv4 and one IPv6 addresses are chosen. Otherwise, many of them
             can be selected. If you want to blacklist IPv6 addresses, you can use !*:*.

       unconfigure system ip management pattern

             Unset any specific pattern for matching management addresses. This option undoes the
             previous one.

       configure system bond-slave-src-mac-type value

             Set the type of src mac in lldp frames sent on bond slaves

             Valid types are:
               real  Slave real mac
               zero  All zero mac
                     An arbitrary fixed value (00:60:08:69:97:ef)
                     Real mac with locally administered bit set. If the real mac already has the
                     locally administered bit set, fallback to the fixed value.

             Default value for bond-slave-src-mac-type is local.  Some switches may complain when
             using one of the two other possible values (either because 00:00:00:00:00:00 is not
             a valid MAC or because the MAC address is flapping from one port to another). Using
             local might lead to a duplicate MAC address on the network (but this is quite

       configure lldp portidsubtype ifname | macaddress | local value [description description]

             Force port ID subtype. By default, lldpcli will use the MAC address as port
             identifier and the interface name as port description, unless the interface has an
             alias. In this case, the interface name will be used as port identifier and the
             description will be the interface alias. With this command, you can force the port
             identifier to be the interface name (with ifname), the MAC address (with macaddress)
             or a local value (with value).  In the latest case, the local value should be
             provided.  Optionally, a port description can also be provided after the local

       configure lldp tx-interval interval

             Change transmit delay to the specified value in seconds. The transmit delay is the
             delay between two transmissions of LLDP PDU. The default value is 30 seconds.

       configure lldp tx-hold hold

             Change transmit hold value to the specified value. This value is used to compute the
             TTL of transmitted packets which is the product of this value and of the transmit
             delay. The default value is 4 and therefore the default TTL is 120 seconds.

       configure lldp custom-tlv oui oui subtype subtype [oui-info content]

             Emit a custom TLV for OUI oui, with subtype subtype and optionnaly with the bytes
             specified in content.  Both oui and content should be a comma-separated list of
             bytes.  oui must be exactly 3-byte long.

       unconfigure lldp custom-tlv

             Remove any previously configured custom TLV.

       configure med fast-start enable | tx-interval interval

             Configure LLDP-MED fast start mechanism. When a new LLDP-MED-enabled neighbor is
             detected, fast start allows lldpd to shorten the interval between two LLDPDU.
             enable should enable LLDP-MED fast start while tx-interval specifies the interval
             between two LLDPDU in seconds. The default interval is 1 second. Once 4 LLDPDU have
             been sent, the fast start mechanism is disabled until a new neighbor is detected.

       unconfigure med fast-start

             Disable LLDP-MED fast start mechanism.

       configure [ports ethX [,...]] med location coordinate latitude latitude longitude
       longitude altitude altitude unit datum datum

             Advertise a coordinate based location on the given ports (or on all ports if no port
             is specified). The format of latitude is a decimal floating point number followed
             either by N or S.  The format of longitude is a decimal floating point number
             followed either by E or W.  altitude is a decimal floating point number followed
             either by m when expressed in meters or f when expressed in floors. A space is
             expected between the floating point number and the unit.  datum is one of those

             A valid use of this command is:
                   configure ports eth0 med location coordinate latitude 48.85667N longitude
                   2.2014E altitude 117.47 m datum WGS84

       configure [ports ethX [,...]] med location address country country [type value [...]]

             Advertise a civic address on the given ports (or on all ports if no port is
             specified).  country is the two-letter code representing the country. The remaining
             arguments should be paired to form the address. The first member of each pair
             indicates the type of the second member which is a free-form text. Here is the list
             of valid types:

                   city "Roseville"

       configure [ports ethX [,...]] med location elin number

             Advertise the availability of an ELIN number. This is used for setting up emergency
             call. If the provided number is too small, it will be padded with 0. Here is an
             example of use:
                   configure ports eth2 med location elin 911

       configure [ports ethX [,...]] med policy application application [unknown] [tagged] [vlan
       vlan] [priority priority] [dscp dscp]

             Advertise a specific network policy for the given ports (or for all ports if no port
             was provided). Only the application type is mandatory.  application should be one of
             the following values: static const struct value_string port_med_policy_map[] = {
                     ·   voice
                     ·   voice-signaling

                     ·   streaming-video
                     ·   video-signaling

             The unknown flag tells that the network policy for the specified application type is
             required by the device but is currently unknown. This is used by Endpoint Devices,
             not by Network Connectivity Devices. If not specified, the network policy for the
             given application type is defined.

             When a VLAN is specified with vlan tells which 802.1q VLAN ID has to be advertised
             for the network policy. A valid value is between 1 and 4094.  tagged tells the VLAN
             should be tagged for the specified application type.  priority allows one to specify
             IEEE 802.1d / IEEE 802.1p Layer 2 Priority, also known as Class of Service (CoS), to
             be used for the specified application type. This field is usually ignored if no VLAN
             is specified. It should be one of those values:
                     ·   background
                     ·   spare
                     ·   best-effort

                     ·   voice
                     ·   network-control

             dscp represents the DSCP value to be advertised for the given network policy.
             DiffServ/Differentiated Services Code Point (DSCP) value as defined in IETF RFC 2474
             for the specified application type. Value: 0 (default per RFC 2475) through 63.
             Note: The class selector DSCP values are backwards compatible for devices that only
             support the old IP precedence Type of Service (ToS) format. (See the RFCs for what
             these values mean)

             A valid use of this command is:
                   configure med policy application voice vlan 500 priority voice dscp 46

       configure [ports ethX [,...]] med power pse | pd source source priority priority value

             Advertise the LLDP-MED POE-MDI TLV for the given ports or for all interfaces if no
             port is provided.  One can act as a PD (power consumer) or a PSE (power provider).
             No check is done on the validity of the parameters while LLDP-MED requires some

             ·   PD shall never request more power than physical 802.3af class.

             ·   PD shall never draw more than the maximum power advertised by PSE.

             ·   PSE shall not reduce power allocated to PD when this power is in use.

             ·   PSE may request reduced power using conservation mode

             ·   Being PSE or PD is a global paremeter, not a per-port parameter.  lldpcli does
                 not enforce this: a port can be set as PD or PSE. LLDP-MED also requires for a
                 PSE to only have one power source (primary or backup). Again, lldpcli does not
                 enforce this. Each port can have its own power source. The same applies for PD
                 and power priority. LLDP-MED MIB does not allow this kind of representation.

             Valid types are:
               pse   Power Sourcing Entity (power provider)
               pd    Power Device (power consumer)

             Valid sources are:
               unknown  Unknown
               primary  For PSE, the power source is the primary power source.
               backup   For PSE, the power source is the backup power source or a power
                        conservation mode is asked (the PSE may be running on UPS for example).
               pse      For PD, the power source is the PSE.
               local    For PD, the power source is a local source.
               both     For PD, the power source is both the PSE and a local source.

             Valid priorities are:
               unknown    Unknown priority
               critical   Critical
               high       High
               low        Low

             value should be the total power in milliwatts required by the PD device or available
             by the PSE device.

             Here is an example of use:
                   configure med power pd source pse priority high value 5000

       configure [ports ethX [,...]] dot3 power pse | pd [supported] [enabled] [paircontrol]

             Advertise Dot3 POE-MDI TLV for the given port or for all ports if none was provided.
             One can act as a PD (power consumer) or a PSE (power provider). This configuration
             is distinct of the configuration of the transmission of the LLDP-MED POE-MDI TLV but
             the user should ensure the coherency of those two configurations if they are used

             supported means that MDI power is supported on the given port while enabled means
             that MDI power is enabled.  paircontrol is used to indicate if pair selection can be
             controlled. Valid values forr powerpairs are:
               signal  The signal pairs only are in use.
               spare   The spare pairs only are in use.

             When specified, class is a number between 0 and 4.

             The remaining parameters are in conformance with 802.3at and are optional.  type
             should be either 1 or 2, indicating which if the device conforms to 802.3at type 1
             or 802.3at type 2. Values ofr source and priority are the same as for LLDP-MED POE-
             MDI TLV.  requested and allocated are expressed in milliwats.

             Here are two valid uses of this command:
