Usage Guidelines

Usage Scenario

To view information about optional TLVs that a device can send, run the display lldp tlv-config command. The command output helps you check whether TLVs that need to be sent are configured or whether TLVs that do not need to be sent have been deleted.

Prerequisites

LLDP has been globally enabled using the lldp enable command in the system view, and LLDP has also been enabled on interfaces using the lldp enable command in the interface view.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display information about the optional TLVs that can be sent by GE 0/1/1.
