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).
