.Sh DESCRIPTION
The
.Nm
program controls
.Xr lldpd 8
daemon.
.Pp
When no command is specified,
.Nm
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.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl d
Enable more debugging information.
.It Fl u Ar socket
Specify the Unix-domain socket used for communication with
.Xr lldpd 8 .
.It Fl v
Show
.Nm
version.
.It Fl f Ar format
Choose the output format. Currently
.Em plain ,
.Em xml ,
.Em json
and
.Em keyvalue
formats are available. The default is
.Em plain .
.It Fl c Ar 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
.Li .conf .
Order is alphabetical.
.El
.Pp
When invoked as
.Nm lldpctl ,
.Nm
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.
.Pp
The following commands are supported by
.Nm .
When there is no ambiguity, the keywords can be abbreviated. For
example,
.Cd show neighbors ports eth0 summary
and
.Cd sh neigh p eth0 sum
are the same command.
.Bd -ragged -offset XX
.Cd exit
.Bd -ragged -offset XXXXXX
Quit
.Nm .
.Ed

.Cd help Op ...
.Bd -ragged -offset XXXXXX
Display general help or help about a command. Also, you can get help
using the completion or by pressing the
.Ic ?
key. However, completion and inline help may be unavailable if
.Nm
was compiled without readline support but
.Cd help
command is always available.
.Ed

.Cd show neighbors
.Op ports Ar ethX Op ,...
.Op Cd details | summary
.Op Cd hidden
.Bd -ragged -offset XXXXXX
Display information about each neighbor known by
.Xr lldpd 8
daemon. With
.Cd summary ,
only a the name and the port description of each remote host will be
displayed. On the other hand, with
.Cd details ,
all available information will be displayed, giving a verbose
view. When using
.Cd 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.
.Ed

.Cd show chassis
.Op Cd details | summary
.Bd -ragged -offset XXXXXX
Display information about local chassis. With
.Cd summary ,
most details are skipped. On the other hand, with
.Cd details ,
all available information will be displayed, giving a verbose
view.
.Ed

.Cd watch
.Op ports Ar ethX Op ,...
.Op Cd details | summary
.Op Cd hidden
.Bd -ragged -offset XXXXXX
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.
.Cd hidden , summary
and
.Cd details
have the same meaning than previously described.
.Ed

.Cd show configuration
.Bd -ragged -offset XXXXXX
Display global configuration of
.Xr lldpd 8
daemon.
.Ed

.Cd show statistics
.Op ports Ar ethX Op ,...
.Op Cd summary
.Bd -ragged -offset XXXXXX
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
.Cd summary
the statistics of each port is summed.
.Ed

.Cd update
.Bd -ragged -offset XXXXXX
Make
.Xr lldpd 8
update its information and send new LLDP PDU on all interfaces.
.Ed

.Cd configure
.Cd system hostname Ar name
.Bd -ragged -offset XXXXXX
Override system hostname with the provided value. By default, the
system name is found from the resolved value of
.Ic uname -n .
.Ed

.Cd unconfigure
.Cd system hostname
.Bd -ragged -offset XXXXXX
Do not override system hostname and restore the use of the node name.
.Ed

.Cd configure
.Cd system description Ar description
.Bd -ragged -offset XXXXXX
Override chassis description with the provided value instead of using
kernel name, node name, kernel version, build date and architecture.
.Ed

.Cd unconfigure
.Cd system description
.Bd -ragged -offset XXXXXX
Do not override chassis description and use a value computed from node
name, kernel name, kernel version, build date and architecture instead.
.Ed

.Cd configure
.Cd system platform Ar description
.Bd -ragged -offset XXXXXX
Override platform description with the provided value instead of using
kernel name. This value is currently only used for CDP.
.Ed

.Cd unconfigure
.Cd system platform
.Bd -ragged -offset XXXXXX
Do not override platform description and use the kernel name. This
option undoes the previous one.
.Ed

.Cd configure
.Cd system interface pattern Ar pattern
.Bd -ragged -offset XXXXXX
Specify which interface to listen and send LLDPDU to. Without this
option,
.Nm 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
.Em eth*,!eth1,!eth2
.Nm lldpd
will only use interfaces starting by
.Em eth
with the exception of
.Em eth1
and
.Em eth2 .
While with
.Em *,!eth*,!!eth1
.Nm
will use all interfaces, except interfaces starting by
.Em eth
with the exception of
.Em eth1 .
When an exact match is found, it will circumvent some tests. For example, if
.Em eth0.12
is specified, it will be accepted even if this is a VLAN interface.
.Ed

.Cd unconfigure
.Cd system interface pattern
.Bd -ragged -offset XXXXXX
Remove any previously configured interface pattern and use all
physical interafces. This option undoes the previous one.
.Ed

.Cd configure
.Cd system interface description
.Bd -ragged -offset XXXXXX
Some OS allows the user to set a description for an interface. Setting
this option will enable
.Nm lldpd
to override this description with the name of the peer neighbor if one
is found or with the number of neighbors found.
.Ed

.Cd unconfigure
.Cd system interface descripton
.Bd -ragged -offset XXXXXX
Do not update interface description with the name of the peer
neighbor. This option undoes the previous one.
.Ed

.Cd configure
.Cd system interface promiscuous
.Bd -ragged -offset XXXXXX
Enable promiscuous mode on managed interfaces.
.Pp
When the interface is not managed any more (or when quitting
.Nm ) ,
the interface is left in promiscuous mode as it is difficult to know
if someone else also put the interface in promiscuous mode.
.Pp
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.
.Pp
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.
.Ed

.Cd unconfigure
.Cd system interface promiscuous
.Bd -ragged -offset XXXXXX
Do not set promiscuous mode on managed interfaces. This option does
not disable promiscuous mode on interfaces already using this mode.
.Ed

.Cd configure
.Cd system ip management pattern Ar pattern
.Bd -ragged -offset XXXXXX
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
.Em !*:* .
.Ed

.Cd unconfigure
.Cd system ip management pattern
.Bd -ragged -offset XXXXXX
Unset any specific pattern for matching management addresses. This
option undoes the previous one.
.Ed

.Cd configure
.Cd system bond-slave-src-mac-type Ar value
.Bd -ragged -offset XXXXXX
Set the type of src mac in lldp frames sent on bond slaves

Valid types are:
.Bl -tag -width "XXX." -compact -offset XX
.It Sy real
Slave real mac
.It Sy zero
All zero mac
.It Sy fixed
An arbitrary fixed value
.Li ( 00:60:08:69:97:ef )
.It Sy local
Real mac with locally administered bit set. If the real mac already
has the locally administered bit set, fallback to the fixed value.
.El
.Pp
Default value for
.Nm bond-slave-src-mac-type
is
.Nm local .
Some switches may complain when using one of the two other possible
values (either because
.Li 00:00:00:00:00:00
is not a valid MAC or because the MAC address is flapping from one
port to another). Using
.Sy local
might lead to a duplicate MAC address on the network (but this is
quite unlikely).
.Ed

.Cd configure
.Cd lldp portidsubtype
.Cd ifname | macaddress
.Pp
.Cd configure
.Op ports Ar ethX Op ,...
.Cd lldp portidsubtype
.Cd local Ar value Op Cd description Ar description
.Bd -ragged -offset XXXXXX
Force port ID subtype. By default,
.Nm
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
.Cd ifname ) ,
the MAC address (with
.Cd macaddress )
or a local value (with
.Cd value ) .
In the latest case, the local value should be provided.
Optionally, a port description can also be provided after the local
value.
.Ed

.Cd configure
.Cd lldp tx-interval Ar interval
.Bd -ragged -offset XXXXXX
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.
.Ed

.Cd configure
.Cd lldp tx-hold Ar hold
.Bd -ragged -offset XXXXXX
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.
.Ed

.Cd configure
.Cd lldp custom-tlv oui Ar oui
.Cd subtype Ar subtype
.Op Cd oui-info Ar content
.Bd -ragged -offset XXXXXX
Emit a custom TLV for OUI
.Ar oui ,
with subtype
.Ar subtype
and optionnaly with the bytes specified in
.Ar content .
Both
.Ar oui
and
.Ar content
should be a comma-separated list of bytes.
.Ar oui
must be exactly 3-byte long.
.Ed

.Cd unconfigure
.Cd lldp custom-tlv
.Bd -ragged -offset XXXXXX
Remove any previously configured custom TLV.
.Ed

.Cd configure med fast-start
.Cd enable | tx-interval Ar interval
.Bd -ragged -offset XXXXXX
Configure LLDP-MED fast start mechanism. When a new LLDP-MED-enabled
neighbor is detected, fast start allows
.Nm lldpd
to shorten the interval between two LLDPDU.
.Cd enable
should enable LLDP-MED fast start while
.Cd 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.
.Ed

.Cd unconfigure med fast-start
.Bd -ragged -offset XXXXXX
Disable LLDP-MED fast start mechanism.
.Ed

.Cd configure
.Op ports Ar ethX Op ,...

.Cd latitude Ar latitude
.Cd longitude Ar longitude
.Cd altitude Ar altitude Ar unit
.Cd datum Ar datum
.Bd -ragged -offset XXXXXX
Advertise a coordinate based location on the given ports (or on all
ports if no port is specified). The format of
.Ar latitude
is a decimal floating point number followed either by
.Em N
or
.Em S .
The format of
.Ar longitude
is a decimal floating point number followed either by 
.Em E
or
.Em W .
.Ar altitude
is a decimal floating point number followed either by
.Em m
when expressed in meters or
.Em f

.Cd configure
.Op ports Ar ethX Op ,...
.Cd med location elin
.Ar number
.Bd -ragged -offset XXXXXX
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:
.D1 configure ports eth2 med location elin 911

.Cd med policy
.Cd application Ar application
.Op Cd unknown
.Op Cd tagged
.Op Cd vlan Ar vlan
.Op Cd priority Ar priority
.Op Cd dscp Ar dscp
.Bd -ragged -offset XXXXXX
Advertise a specific network policy for the given ports (or for all
ports if no port was provided). Only the application type is
mandatory.
.Ar application
should be one of the following values:

.El
.Pp
The
.Cd 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.
.Pp
When a VLAN is specified with
.Cd vlan
tells which 802.1q VLAN ID has to be advertised for the network
policy. A valid value is between 1 and 4094.
.Cd tagged
tells the VLAN should be tagged for the specified application type.
.Cd 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:

.Pp
.Ar 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)

.Ed

.Cd configure
.Op ports Ar ethX Op ,...
.Cd med power pse | pd
.Cd source Ar source
.Cd priority Ar priority
.Cd value Ar value
.Bd -ragged -offset XXXXXX
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:
.Bl -bullet
.It
PD shall never request more power than physical 802.3af class.
.It
PD shall never draw more than the maximum power advertised by PSE.
.It
PSE shall not reduce power allocated to PD when this power is in use.
.It
PSE may request reduced power using conservation mode
.It
Being PSE or PD is a global paremeter, not a per-port parameter.
.Nm
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,
.Nm
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.
.El
.Pp
Valid types are:
.Bl -tag -width "XXX." -compact -offset XX
.It Sy pse
Power Sourcing Entity (power provider)
.It Sy pd
Power Device (power consumer)
.El
.Pp
Valid sources are:
.Bl -tag -width "XXXXXXX" -compact -offset XX
.It Sy unknown
Unknown
.It Sy primary
For PSE, the power source is the primary power source.
.It Sy 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).
.It Sy pse
For PD, the power source is the PSE.
.It Sy local
For PD, the power source is a local source.
.It Sy both
For PD, the power source is both the PSE and a local source.
.El
.Pp
Valid priorities are:
.Bl -tag -width "XXXXXXXXX" -compact -offset XX
.It Sy unknown
Unknown priority
.It Sy critical
Critical
.It Sy high
High
.It Sy low

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

.Bd -ragged -offset XXXXXX
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.
.Pp
.Ar supported
means that MDI power is supported on the given port while
.Ar enabled
means that MDI power is enabled.
.Ar paircontrol
is used to indicate if pair selection can be controlled. Valid values
forr
.Ar powerpairs
are:
.Bl -tag -width "XXXXXX" -compact -offset XX
.It Sy signal
The signal pairs only are in use.
.It Sy spare
The spare pairs only are in use.
.El
.Pp
When specified,
.Ar class
is a number between 0 and 4.
.Pp
The remaining parameters are in conformance with 802.3at and are optional.
.Ar 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
.Ar source
and
.Ar priority
are the same as for LLDP-MED POE-MDI TLV.
.Ar requested
and
.Ar allocated
are expressed in milliwats.
