(Optional) Disabling LLDP on an Interface

(Optional) Disabling LLDP on an Interface

Context

LLDP can be enabled in the system view and the interface view.

  • When LLDP is enabled in the system view, LLDP is enabled on all interfaces.
  • When LLDP is disabled in the system view, LLDP is disabled on all interfaces.
  • An interface can send and receive LLDP packets only after LLDP is enabled in both the system view and the interface view.
  • After LLDP is disabled globally, the commands for enabling and disabling LLDP on an interface do not take effect.
  • If LLDP needs to be disabled on some interfaces, first enable LLDP globally, and run the lldp disable command on these interfaces. To re-enable LLDP on these interfaces, run the undo lldp disable command in the views of these interfaces.
NOTE:
  • Only physical interfaces support LLDP. Logical interfaces such as the VLANIF and Eth-Trunk interfaces do not support LLDP.
  • On an Eth-Trunk, LLDP can only be enabled on member interfaces. LLDP status of a member interface does not affect that of another.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run lldp disable

    LLDP is disabled on the interface.

  4. Run commit

    The configuration is committed.
