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.

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.

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

       -h     Print usage instructions.

       -m address
              Management address for unnumbered interfaces, can be specified for IPv4 and IPv6.

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

       -o     Run only once, useful for quick troubleshooting.

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

       -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.

       -z     Save received peer information in interface descriptions  (requires  SIOCSIFDESCR  support).  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.

       -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).
