ladvdc - display link layer advertisements
SYNOPSIS
ladvdc [ INTERFACE ] [ INTERFACE ] ...
DESCRIPTION
ladvdc displays link layer advertisements received by ladvd(8) running in receive mode (via -a or -z). Optionally a list of protocols
and/or interfaces can be supplied to limit the amount of information displayed. Only users in the ladvd group are allowed to connect to the
daemon.
OPTIONS -b Print output in a format suitable for inclusion in shell scripts.
-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 Print a full decode of each advertisement (not implemented).
-h Print usage instructions.
-o Only print the first advertisement.
-p http://domain.tld/script
Post decoded packets to the supplied url.
-L Parse LLDP (Link Layer Discovery Protocol).
-C Parse CDP (Cisco Discovery Protocol).
-E Parse EDP (Extreme Discovery Protocol).
-F Parse FDP (Foundry Discovery Protocol).
-N Parse NDP (Nortel Discovery Protocol) formerly called SynOptics Network Management Protocol (SONMP).

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).
