Introduction
The Cisco Discovery
Protocol (CDP) is a device discovery protocol that runs over Layer 2 (the Data
Link layer) on all Cisco-manufactured devices (routers, bridges, access
servers, and switches). CDP allows network management applications to
automatically discover and learn about other Cisco devices connected to the
network.
To support non-Cisco devices and to allow for interoperability
between other devices, the Cisco CRS Router also supports the IEEE 802.1AB LLDP.
LLDP is also a neighbour discovery protocol that is used for network devices to
advertise information about themselves to other devices on the network. This
protocol runs over the Data Link Layer, which allows two systems running
different network layer protocols to learn about each other.
LLDP supports a set of attributes that it uses to learn
information about neighbour devices. These attributes have a defined format
known as a Type-Length-Value (TLV). LLDP supported devices can use TLVs to
receive and send information to their neighbours. Details such as configuration
information, device capabilities, and device identity can be advertised using
this protocol.
LLDP is a one-way
protocol. The basic operation of LLDP consists of a device enabled for transmit
of LLDP information sending periodic advertisements of information in LLDP
frames to a receiving device. Devices are identified
using a combination of the Chassis ID and Port ID TLVs to create an MSAP (MAC
Service Access Point). The receiving device saves the information about a
neighbour for a certain amount time specified in the TTL TLV, before ageing and
removing the information.
There are a few LLDP
timers and these are configurable:
·
Holdtime. This is the length of time that information from an LLDP
packet should be held by the receiving device before aging and removing it. The
default is 30 Seconds and is configurable between 0 and 65535 seconds. (The recommendation is
to keep at default)
·
Reinit. This is the length of time to delay the initialisation of LLDP
on an interface. The default is 2 seconds and is configurable between 2-5
seconds. (The recommendation is to keep at default)
·
Timer. This specifies the LLDP packet rate. The default is 30
seconds and is configurable between 5 and 65534 seconds. (The recommendation is
to keep at default)
There are a few
unsupported LLDP features, mainly:
·
LLDP-MED organizationally unique extension—However,
interoperability still exists between other devices that do support this
extension.
·
LLDP TLVs cannot be disabled on a per-interface basis; However,
certain optional TLVs can be disabled globally.
·
LLDP is
NOT supported on Bundle interfaces. LLDP is supported on physical interfaces
which are member of any bundle interface.
LLDP was introduced in XR on the CRS in
release 4.2.3 and on the ASR9K in release 4.1.0, However LLDP is not supported
on XR enabled 12K’s.
On a XR 12K, the software will let you enter the configuration, but will bring
up an error message when you try to commit it:

Configuring LLDP
LLDP is disabled by
default.
To check if LLDP is
enabled use the command:
RP/0/RP1/CPU0:ROUTER#show LLDP
Fri Oct 25 00:59:44.004 EST
% LLDP is not enabled
<<<<<<<<<<<<<LLDP IS NOT
ENABLED.
RP/0/RP1/CPU0:ROUTER#
If LLDP is
enabled the output would be:
RP/0/RP1/CPU0:ROUTER#sh LLDP
Fri Oct 25 01:09:08.964 EST
Global LLDP information:
Status: ACTIVE
LLDP advertisements are sent every 30
seconds
LLDP hold time advertised is 120
seconds
LLDP interface reinitialisation delay
is 2 seconds
To enable LLDP
use the global command LLDP:
RP/0/RP1/CPU0:ROUTER#conf t
Fri Oct 25 01:08:34.221 EST
RP/0/RP1/CPU0:ROUTER(config)#LLDP
RP/0/RP1/CPU0:ROUTER(config-LLDP)#commit
Fri Oct 25 01:08:45.538 EST
This
will enable LLDP on all supported interfaces for both transmit and receive
directions. It will also enable the default timers as indicated above with the
command ‘show LLDP’
To
confirm what interfaces have been enabled with the command ‘LLDP’ use the
command ‘show LLDP interface’:

Disabling LLDP at interface level
If
you are required to disable LLDP on any interfaces then you can override the
default LLDP operation at interface level by disabling receive and/or transmit
operations. (Remember LLDP is a one way protocol). For example:
RP/0/RP1/CPU0:ROUTER#sh LLDP

Disabling LLDP TVLs
The default is that all TLVs
(Type-Length-Values) are sent in LLDP packets. Certain TLV s are mandatory for LLDP
operation. These are Chassis ID, Port ID and Time to Live. All other TLVs are
optional and the transmission of them can be suppressed. The example below
shows how to disable these TLVs:

Verifying LLDP
The following commands are useful for
verifying your LLDP configuration:
‘Show

neighbours with the * option, or a single neighbour by specifying the name of a
specific neighbour. This command displays the far end interface, the name of
the far end router, its software version and far end IP addresses.
RP/0/RP1/CPU0:ROUTER#show

‘show LLDP traffic’ displays the
statistics for LLDP. For example:
RP/0/RP1/CPU0:ROUTER#show LLDP traffic
Thu Dec 5 07:17:35.520 EST
LLDP traffic statistics:
Total frames out: 19182197
Total entries aged: 71
Total frames in: 388202
Total frames received in
error: 0
Total frames discarded: 8
Total TLVs discarded: 0
Total TLVs unrecognized: 0
Total frames out is the number of LLDP advertisements sent from the
device.
Total entries aged are the number of LLDP
neighbor entries removed due to expiration of the hold time.
Total frames in is the number of LLDP
advertisements received by the device.
Total frames received in error is the number
of times the LLDP advertisements contained errors of any type.
Total frames discarded is the number of
times the LLDP process discarded an incoming advertisement.
Total TLVs discarded is the number of
times the LLDP process discarded a Type Length Value (TLV) from an LLDP frame.
Total TLVs unrecognized are the number
of TLVs that could not be processed because the content of the TLV was not
recognized by the device or the contents of the TLV were incorrectly specified.
‘clear LLDP’ This command resets LLDP traffic counters or neighbour information.
Counters specifies that LLDP traffic counters are cleared and table specifies
that information in the LLDP neighbour table is cleared. For example:

Debugging LLDP
There are a variety of
LLDP debug commands:
RP/0/RP1/CPU0:ROUTER#debug LLDP ?
all All LLDP debugs
errors LLDP error information

tlvs LLDP TLVs
trace LLDP trace information
verbose LLDP verbose information
The debug headings are
self-explanatory, however as with all debugs, they may execute a lot of
information and care should be taken when issuing any debug command.
For example, the
output from ‘debug LLDP events’:
