Is LLDP enabled by default?
LLDP is enabled by default on all supported interfaces to send and to receive LLDP information. If the interface is configured as a tunnel port, LLDP is automatically disabled.
What is LLDP in Linux?
LLDP is a network layer 2 protocol, called “Link Layer Discovery Protocol”. It transmits much information about the device and ports to all network neighbors. Link Layer Discovery Protocol (LLDP) is one of the most under-utilized yet extremely useful networking protocols you may never have heard of.
Can I turn off LLDP?
Disabling and Enabling LLDP on an interface Enter global configuration mode. Issue interface interface-id command. This will specify the interface on which you are disabling LLDP. Issue no lldp transmit or no lldp receive.

Where is LLDP used?
LLDP is mainly used in wired Ethernet-connected devices to facilitate management of network resources and simplify networking tasks for administrators in a multi-vendor network.
What is LLDP protocol used for?
Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices to advertise the attributes of a device. These attributes contain type, length, and value descriptions and are referred to as TLVs. LLDP supported devices use TLVs to receive and send information to neighboring devices.
How is LLDP used?
LLDP enables Ethernet network devices, such as switches and routers, to transmit and/or receive descriptive information, and to store such information learned about other devices. The data sent and received by LLDP is useful for many reasons: ∎ devices can discover neighbors—other devices directly connected to it.
