NAME
lldpcli, lldpctl — control LLDP daemon
SYNOPSIS
lldpcli [-dv] [-u file] [-f format] [-c file] [command ...]
lldpctl [-dv] [-u file] [-f format] [interfaces ...]
DESCRIPTION
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 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.
exit
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.
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.
update
Make lldpd(8) update its information and send new LLDP PDU on all interfaces.
configure system description description
Override chassis description with the provided value instead of using kernel name,
node name, kernel version, build date and architecture.
configure system platform description
Override platform description with the provided value instead of using kernel name.
This value is currently only used for CDP.
configure system interface pattern pattern
Set the pattern of valid interfaces to use. When not set, lldpd will listen on all
available 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. When an interface is both specified with and
without an exclamation mark, it is blacklisted. For example, with eth*,!eth1,!eth2
lldpd will only listen to interfaces starting by eth with the exception of eth1 and
eth2.
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.
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 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
fixed
An arbitrary fixed value (from a 3Com card)
local
Real mac with locally administered bit set. If the real mac already has the
locally administered bit set, default to the fixed value.
Default value for bond-slave-src-mac-type is fixed
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
values:
• WGS84
• NAD83
• NAD83/MLLW
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:
• language
• country-subdivision
• county
• city
• city-division
• block
• street
• direction
• trailing-street-suffix
• street-suffix
• number
• number-suffix
• landmark
• additional
• name
• zip
• building
• unit
• floor
• room
• place-type
• script
A valid use of this command is:
configure ports eth1 med location address US street "Commercial Road" 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] [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
• guest-voice
• guest-voice-signaling
• softphone-voice
• video-conferencing
• 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. 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. It should be one of those
values:
• background
• spare
• best-effort
• excellent-effort
• controlled-load
• video
• 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
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
restrictions:
• 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]
powerpairs powerpairs [class class] [type type source source priority priority requested
requested allocated allocated]
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
together.
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:
configure ports eth3 dot3 power pse supported enabled paircontrol powerpairs
spare class 3
configure dot3 power pd supported enabled powerpairs spare class 3 type 1
source pse priority low requested 10000 allocated 15000
pause
Pause lldpd operations. lldpd will not send any more frames or receive ones. This
can be undone with resume command.
resume
Resume lldpd operations. lldpd will start to send and receive frames. This command
is issued internally after processing configuration but can be used at any time if a
manual pause command is issued.
FILES
/var/run/lldpd.socket Unix-domain socket used for communication with lldpd(8).
