(Optional) Disabling LLDP on an Interface
Context
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 and Eth-Trunk.
- On an Eth-Trunk, LLDP can only be enabled on member interfaces. The interfaces enabled with LLDP and not enabled with LLDP can exist in the same Eth-Trunk.
