-# VPP Link Layer Discovery Protocol (LLDP) implementation {#lldp_doc}
-
-This is a memo intended to contain documentation of the VPP LLDP implementation
-Everything that is not directly obvious should come here.
-
-
-## LLDP
-LLDP is a link layer protocol to advertise the capabilities and current status of the system.
-
-There are 2 nodes handling LLDP
-
-1.) input-node which processes incoming packets and updates the local database
-2.) process-node which is responsible for sending out LLDP packets from VPP side
-
-
-### Configuration
-
-LLDP has a global configuration and a per-interface enable setting.
-
-Global configuration is modified using the "set lldp" command
-
-set lldp [system-name <string>] [tx-hold <value>] [tx-interval <value>]
-
-system-name: the name of the VPP system sent to peers in the system-name TLV
-tx-hold: multiplier for tx-interval when setting time-to-live (TTL) value in the LLDP packets (TTL = tx-hold * tx-interval + 1, if TTL > 65535, then TTL = 65535)
-tx-interval: time interval between sending out LLDP packets
-
-Per interface setting is done using the "set interface lldp" command
-
-set interface lldp <interface> | if_index <idx> [port-desc <string>] [disable]
-
-interface: the name of the interface for which to enable/disable LLDP
-if_index: sw interface index can be used if interface name is not used.
-port-desc: port description
-disable: LLDP feature can be enabled or disabled per interface.
-
-### Configuration example
-
-Configure system-name as "VPP" and transmit interval to 10 seconds:
-
-set lldp system-name VPP tx-interval 10
-
-Enable LLDP on interface TenGigabitEthernet5/0/1 with port description
-
-set interface lldp TenGigabitEthernet5/0/1 port-desc vtf:eth0
-
-
-### Operational data
-
-The list of LLDP-enabled interfaces which are up can be shown using "show lldp" command
-
-Example:
-DBGvpp# show lldp
-Local interface Peer chassis ID Remote port ID Last heard Last sent Status
-GigabitEthernet2/0/1 never 27.0s ago inactive
-TenGigabitEthernet5/0/1 8c:60:4f:dd:ca:52 Eth1/3/3 20.1s ago 18.3s ago active
-
-All LLDP configuration data with all LLDP-enabled interfaces can be shown using "show lldp detail" command
-
-Example:
-DBGvpp# show lldp detail
-LLDP configuration:
-Configured system name: vpp
-Configured tx-hold: 4
-Configured tx-interval: 30
-
-LLDP-enabled interface table:
-
-Interface name: GigabitEthernet2/0/1
-Interface/peer state: inactive(timeout)
-Last known peer chassis ID:
-Last known peer port ID:
-Last packet sent: 12.4s ago
-Last packet received: never
-
-Interface name: GigabitEthernet2/0/2
-Interface/peer state: interface down
-Last packet sent: never
-
-Interface name: TenGigabitEthernet5/0/1
-Interface/peer state: active
-Peer chassis ID: 8c:60:4f:dd:ca:52(MAC address)
-Remote port ID: Eth1/3/3(Locally assigned)
-Last packet sent: 3.6s ago
-Last packet received: 5.5s ago
