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).

DESCRIPTION
SNMP::Info::SONMP is a subclass of SNMP::Info that provides an object oriented interface to the SynOptics Network Management Protocol
(SONMP) information through SNMP.
SONMP is a Layer 2 protocol that supplies topology information of devices that also speak SONMP, mostly switches and hubs. SONMP is
implemented in SynOptics, Bay, and Nortel devices. SONMP has been rebranded by Bay then Nortel and is know by several different names,
most recently Nortel Discovery Protocol (NDP).
Create or use a device subclass that inherits this class. Do not use directly.
Each device implements a subset of the global and cache entries. Check the return value to see if that data is held by the device.
Inherited Classes
None.
Required MIBs
SYNOPTICS-ROOT-MIB
S5-ETH-MULTISEG-TOPOLOGY-MIB
GLOBAL METHODS
These are methods that return scalar values from SNMP
$sonmp->index_factor()
Returns a number representing the number of ports reserved per slot or switch within the device MIB. Defaults to 32.
$sonmp->slot_offset()
Returns the offset if slot numbering does not start at 0. Defaults to 1.
$sonmp->port_offset()
Returns the offset if port numbering does not start at 0. Defaults to 0.
$cdp->hasCDP()
Is SONMP is active in this device?
$sonmp->cdp_id()
Returns the IP that the device is sending out for its Nmm topology info.
("s5EnMsTopIpAddr")
$sonmp->cdp_run()
Returns true if SONMP is on for this device.
("s5EnMsTopStatus")
$sonmp->mac()
Returns MAC of the advertised IP address of the device.
TABLE METHODS
These are methods that return tables of information in the form of a reference to a hash.
Layer2 Topology info ("s5EnMsTopNmmTable")
$sonmp->sonmp_topo_slot()
Returns reference to hash. Key: Table entry, Value:slot number
("s5EnMsTopNmmSlot")
$sonmp->sonmp_topo_port()
Returns reference to hash. Key: Table entry, Value:Port Number (interface iid)
("s5EnMsTopNmmPort")
$sonmp->sonmp_topo_ip()
Returns reference to hash. Key: Table entry, Value:Remote IP address of entry
("s5EnMsTopNmmIpAddr")
$sonmp->sonmp_topo_seg()
Returns reference to hash. Key: Table entry, Value:Remote Segment ID
("s5EnMsTopNmmSegId")
$sonmp->sonmp_topo_mac()
("s5EnMsTopNmmMacAddr")
Returns reference to hash. Key: Table entry, Value:Remote MAC address
$sonmp->sonmp_topo_platform
Returns reference to hash. Key: Table entry, Value:Remote Device Type
("s5EnMsTopNmmChassisType")
$sonmp->sonmp_topo_localseg
Returns reference to hash. Key: Table entry, Value: Boolean, if bay_topo_seg() is local.
("s5EnMsTopNmmLocalSeg")
Pseudo CDP information
All entries with port=0 are local and ignored.
$sonmp->c_if()
Returns reference to hash. Key: IID, Value: Local port (interfaces)
$sonmp->c_ip()
Returns reference to hash. Key: IID, Value: Remote IP address
If multiple entries exist with the same local port, c_if(), with different IPv4 addresses, c_ip(), there is either a non SONMP device
in between two or more devices or multiple devices which are not directly connected.
Use the data from the Layer2 Topology Table below to dig deeper.
$sonmp->c_port()
Returns reference to hash. Key: IID, Value: Remote port (interfaces)
$sonmp->c_platform()
Returns reference to hash. Key: IID, Value: Remote device type
