NAME

       ladvd - send link layer advertisements

SYNOPSIS

       ladvd [ -a ] [ INTERFACE ] [ INTERFACE ] ...

DESCRIPTION

       ladvd  sends LLDP (Link Layer Discovery Protocol) advertisements on all
       available interfaces. This makes connected  hosts  visible  on  managed
       switches.  By  default  it  will  run  as a privilege-separated daemon.
       Additional protocols can be  enabled  using  the  -C,  -E,  -F  and  -N
       options. Optionally a list of interfaces which ladvd should utilize can
       be supplied. Please note that only physical or  bond/bridge  interfaces
       can be specified, vlan interfaces can only be auto-detected.

INTERFACES

       ladvd detects and uses all configured (UP) physical Ethernet interfaces
       by default, wireless interfaces can  be  enabled  via  the  -w  option.
       Additionally ladvd will recognize bundled interfaces (bridges, bonding)
       and use these to transmit additional information. The  result  is  that
       normally  it should not be necessary to specify interfaces on the ladvd
       command-line.  The  only  reason  for  specifying  interfaces   is   to
       explicitly exclude a particular interface.

OPTIONS

       -a     Auto-enable  protocols  based  on received packets (also enables
              receive mode).

       -d     Dump pcap-compatible packets to stdout which  can  be  piped  to
              tcpdump  (via  "|  tcpdump  -r  -")  or redirected to a file for
              further analysis.

       -e interface
              Exclude a particular interface, no packets will  be  transmitted
              on this interface.

       -f     Run in the foreground and send logging to stderr.

       -h     Print usage instructions.

       -m interface
              The  management  interface  for  this  host.  Addresses  on this
              interface are auto-detected (IPv4 and IPv6).

       -n     Use addresses of the management interface specified via  -m  for
              all interfaces.

       -o     Run only once, useful for quick troubleshooting.

       -r     Receive packets, and use them for various features.

       -s     Be silent, don't transmit any packets.

       -q     Use each interface's hwaddr the generate the chassis-id TLV. Not
              recommended because the chassis-id should be the  same  for  all
              interfaces.

       -t     Use Tun/Tap interfaces.

       -u user
              Switch to this user (defaults to ladvd)

       -v     Increase logging verbosity.

       -w     Use wireless interfaces.

       -y     Save  received  peer  hostname and port description in interface
              descriptions (requires SIOCSIFDESCR support) or Linux ifAliases.
              This also enables receive mode.

       -z     Save   received   peer  hostname  and  port  name  in  interface
              descriptions (requires SIOCSIFDESCR support) or Linux ifAliases.
              This also enables receive mode.

       -c <CC>
              Specify  a  two-letter  ISO 3166 country code (required for LLDP
              location support).

       -l <location>
              Specify the physical location of the host.

       -L     Enable LLDP (Link Layer Discovery Protocol).

       -C     Enable CDP (Cisco Discovery Protocol).

       -E     Enable EDP (Extreme Discovery Protocol).

       -F     Enable FDP (Foundry Discovery Protocol).

       -N     Enable NDP (Nortel Discovery Protocol) formerly called SynOptics
              Network Management Protocol (SONMP).
