lldptool(8) Linux lldptool(8)NAMElldptool - manage the LLDP settings and status of lldpad
SYNOPSISlldptool <command> [options] [argument]
DESCRIPTIONlldptool is used to query and configure lldpad. It connects to the
client interface of lldpad to perform these operations. lldptool will
operate in interactive mode if it is executed without a command. In
interactive mode, lldptool will also function as an event listener to
print out events as they are received asynchronously from lldpad. It
will use libreadline for interactive input when available.
OPTIONS-i [ifname]
specifies the network interface to which the command applies.
Most lldptool commands require specifying a network interface.
-V [tlvid]
specifies the TLV identifier
The tlvid is an integer value used to identify specific LLDP
TLVs. The tlvid value is the Type value for types not equal to
127 (the organizationally specific type). For organizationally
specific TLVs, the tlvid is the value represented by the 3 byte
OUI and 1 byte subtype - where the subtype is the lowest order
byte of the tlvid.
The tlvid can be entered as a numerical value (e.g. 10 or 0xa),
or for supported TLVs, as a keyword. Review the lldptool help
output to see the list of supported TLV keywords.
-n "neighbor" option for commands which can use it (e.g. get-tlv)
-g [bridge scope]
specify the bridge scope this command operates on. Allows to set
and query all LLDP TLV modules for "nearest_bridge" (short:
"nb"), "nearest_customer_bridge" ("ncb") and "near‐
est_nontpmr_bridge" ("nntpmrb") group mac addresses. Configura‐
tions are saved into independent sections in lldpad.conf. If no
bridge scope is supplied this default to "nearest bridge" to
preserve the previous behaviour.
-c <argument list>
"config" option for TLV queries. Indicates that the query is for
the configuration elements for the specified TLV. The argument
list specifies the specific elements to query. If no arguments
are listed, then all configuration elements for the TLV are
returned.
-r show raw client interface messages
-R show only raw Client interface messages
COMMANDS

set TLV information for the specified interface
-l, get-lldp
get LLDP parameters for the specified interface
-L, set-lldp

ARGUMENTS
This section lists arguments which are available for administration of
LLDP parameters. Arguments for basic TLV's (non-organizationally spe‐
cific TLVs) are also described. See the SEE ALSO section for refer‐
ences to other lldptool man pages which contain usage details and argu‐
ments for various organizationally specific TLVs.
adminStatus
Argument for the get-lldp/set-lldp commands. Configures the
LLDP adminStatus parameter for the specified interface. Valid
values are: disabled, rx, tx, rxtx
enableTx
Argument for the get-tlv/set-tlv commands. May be applied per
interface for a specified TLV. Valid values are: yes, no. If
the DCBX TLV enableTx is set to no, then all of the DCB feature
TLVs DCBX advertise settings will be turned off as well. Set‐
ting enableTx to yes for a DCBX TLV will not affect the DCBX
advertise settings.
ipv4 Argument for the get-tlv/set-tlv commands with respect to the
Management Address TLV. The get command will retrieve the con‐
figured value. Set values take the form of an IPv4 address:
A.B.C.D
ipv6 Argument for the get-tlv/set-tlv commands with respect to the
Management Address TLV. The get command will retrieve the con‐
figured value. Set values take the form of an IPv6 address:
1111:2222:3333:4444:5555:6666:7777:8888 and various shorthand
variations.
EXAMPLES
