The Link Layer Discovery Protocol is a vendor-neutral Layer 2 +protocol that allows a network device to advertise its identity and +capabilities on the local network. +.Pp +.Nm +also implements an SNMP subagent using AgentX protocol to interface to +a regular SNMP agent like Net-SNMP. To enable this subagent, you need +something like that in your +.Xr snmpd.conf 5 : +.Bd -literal -offset indent +master agentx +.Ed +.Pp +This daemon implements both reception and sending. It will collect +various information to send LLDP frames to all Ethernet interfaces, +including management address, speed and VLAN names. +.Pp +The options are as follows: +.Bl -tag -width Ds +.It Fl d +Do not daemonize. +If this option is specified, +.Nm +will run in the foreground. When specified one more time, +.Nm +will not log to syslog but only to stderr. Then, this option can be +specified many times to increase verbosity. When specified four times, +debug logs will be enabled. They can be filtered with +.Fl D +flag. +.It Fl D Ar debug +This option allows the user to filter out debugging information by +specifying allowed tokens. This option can be repeated several times +to allow several tokens. This option must be combined with the +.Fl d +flag to have some effect. Only debugging logs can be filtered.

Kernel name +(ie: Linux) will still be shared, and Inventory software version will be set +to 'Unknown'. +.It Fl S Ar description +Override system description with the provided description. The default +description is the kernel name, the node name, the kernel version, the +build date and the architecture (except if you use the +.Fl k +flag described above). +.It Fl P Ar platform +Override the CDP platform name with the provided value. The default +description is the kernel name (Linux). +.It Fl x +Enable SNMP subagent. +With this option, +.Nm +will enable an SNMP subagent using AgentX protocol. This allows you to +get information about local system and remote systems through SNMP. +.It Fl X Ar socket +Enable SNMP subagent using the specified socket. +.Nm +will enable an SNMP subagent using AgentX protocol for the given +socket. This option implies the previous one. The default socket is +usually +.Em /var/agentx/master . +You can specify a socket like +.Em tcp:127.0.0.1:705 +for example. Since the process that will open this socket is enclosed +in a chroot, you need to specify an IP address (not a hostname) when +using a TCP or UDP socket. +.It Fl c +Enable the support of CDP protocol to deal with Cisco routers that do +not speak LLDP. If repeated, CDPv1 packets will be sent even when +there is no CDP peer detected. If repeated once again, CDPv2 packets +will be sent even when there is no CDP peer detected. If repeated once +again (i.e. +.Fl cccc ) , +CDPv1 will be disabled and CDPv2 will be enabled. If repeated once +again (i.e. +.Fl ccccc ) , +CDPv1 will be disabled and CDPv2 will be forced. +.It Fl f +Enable the support of FDP protocol to deal with Foundry routers that do +not speak LLDP. If repeated, FDP packets will be sent even when there +is no FDP peer detected. +.It Fl s +Enable the support of SONMP protocol to deal with Nortel routers and +switches that do not speak LLDP. If repeated, SONMP packets will be +sent even when there is no SONMP peer detected. +.It Fl e +Enable the support of EDP protocol to deal with Extreme routers and +switches that do not speak LLDP. If repeated, EDP packets will be sent +even when there is no EDP peer detected. +.It Fl l +Force to send LLDP packets even when there is no LLDP peer detected +but there is a peer speaking another protocol detected. By default, +LLDP packets are sent when there is a peer speaking LLDP detected or +when there is no peer at all. If repeated, LLDP is disabled. +.It Fl r +Receive-only mode. With this switch, +.Nm +will not send any frame. It will only listen to neighbors. +.It Fl m Ar management +Specify the management addresses of this system. As for interfaces +(described below), this option can use wildcards and inversions. +Without this option, the first IPv4 and the first IPv6 are used. If an +exact IP address is provided, it is used as a management address +without any check. If only negative patterns are provided, only one +IPv4 and one IPv6 addresses are chosen. Otherwise, many of them can be +selected. If you want to remove IPv6 addresses, you can use +.Em !*:* . +If an interface name is matched, the first IPv4 address and the first +IPv6 address associated to this interface will be chosen. +.It Fl u Ar file +Specify the Unix-domain socket used for communication with +.Xr lldpctl 8 . +.It Fl I Ar interfaces +Specify which interface to listen and send LLDPDU to. Without this +option, +.Nm +will use all available physical interfaces. This option can use +wildcards. Several interfaces can be specified separated by commas. +It is also possible to remove an interface by prefixing it with an +exclamation mark. It is possible to allow an interface by +prefixing it with two exclamation marks. An allowed interface beats +a forbidden interface which beats a simple matched interface. For +example, with +.Em eth*,!eth1,!eth2 +.Nm +will only use interfaces starting by +.Em eth +with the exception of +.Em eth1 +and +.Em eth2 . +While with +.Em *,!eth*,!!eth1 +.Nm +will use all interfaces, except interfaces starting by +.Em eth +with the exception of +.Em eth1 . +When an exact match is found, it will circumvent some tests. For example, if +.Em eth0.12 +is specified, it will be accepted even if this is a VLAN interface. +.It Fl C Ar interfaces +Specify which interfaces to use for computing chassis ID. Without this +option, all interfaces are considered. +.Nm +will take the first MAC address from all the considered interfaces +to compute the chassis ID. The logic of this option is the same as for +.Fl I +flag: you can exclude interfaces with an exclamation mark and use +globbing to specify several interfaces. If all interfaces are +removed (with +.Em !* ) , +the system name is used as a chassis ID instead. +.It Fl M Ar class +Enable emission of LLDP-MED frame. Depending on the selected class, +the standard defines which set of TLV should be transmitted. See +section 10.2.1. Some devices may be strict about this aspect. The +class should be one of the following value: +.Bl -tag -width "0:XX" -compact +.It Sy 1 +Generic Endpoint (Class I) +.It Sy 2 +Media Endpoint (Class II). In this case, the standard requires to +define at least one network policy through +.Nm lldpcli . +.It Sy 3 +Communication Device Endpoints (Class III). In this case, the standard +requires to define at least one network policy through +.Nm lldpcli . +.It Sy 4 +Network Connectivity Device +.El +.It Fl i +Disable LLDP-MED inventory TLV transmission. +.Nm +will still receive (and publish using SNMP if enabled) those LLDP-MED +TLV but will not send them. Use this option if you don't want to +transmit sensible information like serial numbers. +.It Fl H Ar hide +Filter neighbors. See section +.Sx FILTERING NEIGHBORS +for details. +.It Fl L Ar lldpcli +Provide an alternative path to +.Nm lldpcli +for configuration. If empty, does not use +.Nm lldpcli +for configuration. +.It Fl O Ar configfile +Override default configuration locations processed by +.Nm lldpcli +at start. If a directory is provided, each file contained in it will be read if ending by +.Sy .conf. +Order is alphabetical. +.It Fl v +Show +.Nm +version. When repeated, show more build information. +.El +.Sh FILTERING NEIGHBORS +In a heterogeneous network, you may see several different hosts on the +same port, even if there is only one physically plugged to this +port. For example, if you have a Nortel switch running LLDP which is +plugged to a Cisco switch running CDP and your host is plugged to the +Cisco switch, you will see the Nortel switch as well because LLDP +frames are forwarded by the Cisco switch. This may not be what you +want. The +.Fl H Ar hide +parameter will allow you to tell +.Nm +to discard some frames that it receives and to avoid to send some +other frames. +.Pp +Incoming filtering and outgoing filtering are +unrelated. Incoming filtering will hide some remote ports to get you a +chance to know exactly what equipment is on the other side of the +network cable. Outgoing filtering will avoid to use some protocols to +avoid flooding your network with a protocol that is not handled by the +nearest equipment. Keep in mind that even without filtering, +.Nm +will speak protocols for which at least one frame has been received +and LLDP otherwise (there are other options to change this behaviour, +for example +.Fl cc , ss , ee , ll +and +.Fl ff +). +.Pp +When enabling incoming filtering, +.Nm +will try to select one protocol and filter out neighbors using other +protocols. To select this protocol, the rule is to take the less used +protocol. If on one port, you get 12 CDP neighbors and 1 LLDP +neighbor, this mean that the remote switch speaks LLDP and does not +filter CDP. Therefore, we select LLDP. When enabling outgoing +filtering, +.Nm +will also try to select one protocol and only speaks this +protocol. The filtering is done per port. Each port may select a +different protocol. +.Pp +There are two additional criteria when enabling filtering: allowing +one or several protocols to be selected (in case of a tie) and +allowing one or several neighbors to be selected. Even when allowing +several protocols, the rule of selecting the protocols with the less +neighbors still apply. If +.Nm +selects LLDP and CDP, this means they have the same number of +neighbors. The selection of the neighbor is random. Incoming filtering +will select a set of neighbors to be displayed while outgoing +filtering will use the selected set of neighbors to decide which +protocols to use: if a selected neighbor speaks LLDP and another one +CDP, +.Nm +will speak both CDP and LLDP on this port. +.Pp +There are some corner cases. A typical example is a switch speaking +two protocols (CDP and LLDP for example). You want to get the +information from the best protocol but you want to speak both +protocols because some tools use the CDP table and some other the LLDP +table. +.Pp +The table below summarize all accepted values for the +.Fl H Ar hide +parameter. The default value is +.Em 15 +which corresponds to the corner case described above. The +.Em filter +column means that filtering is enabled.

Additionaly, when an information + * can be retrieved as an atom, it is usually iterable (L). When an atom can be + * retrieved as a string and as an additional type, the string is expected to be + * formatted. For example, the MAC address of a local port can be retrieved as a + * buffer and a string. As a string, you'll get something like + * "00:11:22:33:44:55". Also, all values that can be get as an integer or a + * buffer can be get as a string too. There is no special formatting in this + * case. "(BS)" means that the string get a special appropriate format. + * + * The name of a key is an indication on the type of atom that information can + * be extracted from. For example, @c lldpctl_k_med_policy_type can be extracted + * from an atom you got by iterating on @c lldpctl_k_port_med_policies. On the + * other hand, @c lldpctl_k_port_descr and @c lldpctl_k_chassis can be retrieved + * from an atom retrieved either by iterating @c lldpctl_k_port_neighbors or + * with @c lldpctl_get_port(). + * + * Some values may be written.

If the change is + * transmitted immediatly, you need to check the error status of the connection + * to know if it has been transmitted correctly. Notably, if you get @c + * LLDPCTL_ERR_WOULDBLOCK, you need to try again later. Usually, changes are + * transmitted immediatly. The exception are changes that need to be grouped to + * be consistent, like a LLDP MED location. When a change is transmitted + * immediatly, it is marked with (O). @c lldpctl_atom_set_str() may accept a @c + * NULL value.

An atom marked with (IS) can be retrieved as an integer and features + * an appropriate representation as a string (usually, the name of a constant) + * which is more meaningful than just the integer. An atom marked as (I) can be + * retrieved as an integer and as a string. In the later case, this is just a + * string representation of the integer. An atom marked with (AL) can be + * retrieved as an atom only and can be iterated over. This is usually a list of + * things.
