NAME

6       ladvd - send link layer advertisements
7

SYNOPSIS

9       ladvd [ -a ] [ INTERFACE ] [ INTERFACE ] ...
10

DESCRIPTION

12       ladvd  sends LLDP (Link Layer Discovery Protocol) advertisements on all
13       available interfaces. This makes connected  hosts  visible  on  managed
14       switches. By default it will run as a privilege-separated daemon. Addi‐
15       tional protocols can be enabled using the -C, -E, -F  and  -N  options.
16       Optionally  a list of interfaces which ladvd should utilize can be sup‐
17       plied.
18

INTERFACES

20       ladvd detects and uses all configured (UP) physical Ethernet interfaces
21       by default, wireless interfaces can be enabled via the -w option. Addi‐
22       tionally ladvd will recognize bundled interfaces (bridges, bonding) and
23       use  these  to transmit additional information. The result is that nor‐
24       mally it should not be necessary to specify  interfaces  on  the  ladvd
25       command-line.  The  only reason for specifying interfaces is to explic‐
26       itly exclude a particular interface.
27

OPTIONS

29       -a     Auto-enable protocols based on received  packets  (also  enables
30              receive mode).
31
32       -d     Dump  pcap-compatible  packets  to  stdout which can be piped to
33              tcpdump (via "| tcpdump -r -") or redirected to a file for  fur‐
34              ther analysis.
35
36       -f     Run in the foreground and send logging to stderr.
37
38       -h     Print usage instructions.
39
40       -m address
41              Management  address  for unnumbered interfaces, can be specified
42              for IPv4 and IPv6.
43
44       -n     Use management addresses specified via -m for all interfaces.
45
46       -o     Run only once, useful for quick troubleshooting.
47
48       -r     Receive packets, and use them for various features.
49
50       -q     Use each interface's hwaddr the generate the chassis-id TLV. Not
51              recommended  because  the  chassis-id should be the same for all
52              interfaces.
53
54       -t     Use Tun/Tap interfaces.
55
56       -u user
57              Switch to this user (defaults to ladvd)
58
59       -v     Increase logging verbosity.
60
61       -w     Use wireless interfaces.
62
63       -z     Save  received  peer  information  in   interface   descriptions
64              (requires SIOCSIFDESCR support). This also enables receive mode.
65
66       -c <CC>
67              Specify  a  two-letter  ISO 3166 country code (required for LLDP
68              location support).
69
70       -l <location>
71              Specify the physical location of the host.
72
73       -C     Enable CDP (Cisco Discovery Protocol).
74
75       -E     Enable EDP (Extreme Discovery Protocol).
76
77       -F     Enable FDP (Foundry Discovery Protocol).
78
79       -N     Enable NDP (Nortel Discovery Protocol) formerly called SynOptics
80              Network Management Protocol (SONMP).
