Usage Guidelines

Usage Scenario

The display lldp tlv-config command displays the TLVs supported by the specified interface or all interfaces, and thus you can know whether the required TLVs are enabled and unneeded TLVs are disabled.

Prerequisites

LLDP has been enabled globally using the lldp enable command.
LLDP has been enabled on the interface using the lldp enable command.

Example

# Display Optional TLVs that can be sent with LLDP packets on GigabitEthernet0/0/1.
