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. Beginning in privileged EXEC mode, follow these steps to disable LLDP on an interface.
Does Cisco support LLDP?
Cisco devices support the IEEE 802.1ab version of LLDP. This allows non-Cisco devices to advertise information about themselves to our network devices. LLDP uses attributes that contain a type, length and value descriptions. These are called TLVs (Type, Length, Value).
How do I enable 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. This will allow packets to be sent or received on that interface.
- Return to privileged exec mode.
