lldp enable (interface view)

lldp enable (interface view)

Function

The lldp enable command enables LLDP on an interface.

The undo lldp enable command disables LLDP on an interface.

After LLDP is enabled in the system view, all interfaces are enabled with LLDP.

Format

lldp enable

undo lldp enable

Parameters

None

Views

GE interface view, MultiGE interface view, XGE interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

After LLDP is enabled on an interface, the interface exchanges LLDP packets with LLDP-enabled neighbors. The interface receives status information from the neighbors and sends the local status information to the neighbors. The NMS then obtains the status information for topology discovery.

Prerequisites

The LLDP function has been enabled globally.

Precautions

LLDP can be enabled in the system view and the interface view.
  • After LLDP is enabled in the system view, all interfaces are enabled with LLDP.
  • After LLDP is disabled in the system view, all LLDP settings are restored to the default settings except the setting of LLDP trap. Therefore, LLDP is also 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, enable LLDP globally first, and run the undo lldp enable command on these interfaces. To re-enable LLDP on these interfaces, run the lldp enable command in the views of these interfaces.
  • LLDP can be enabled and disabled only on the physical interfaces, but cannot be used on logical interfaces such as VLANIF interface.

Example

# Disable LLDP on GigabitEthernet0/0/1.

<Huawei> system-view
[Huawei] interface gigabitethernet 0/0/1
[Huawei-GigabitEthernet0/0/1] undo lldp enable
Warning: This command will delete the configurations of LLDP on the port. Continue?[Y/N]y
