Default LLDP Configuration

Configuration Guidelines

• If the interface is configured as a tunnel port, LLDP is automatically disabled.

• If you first configure a network-policy profile on an interface, you cannot apply the switchport

voice vlan command on the interface. If the switchport voice vlan vlan-id is already configured on

an interface, you can apply a network-policy profile on the interface. This way the interface has the

voice or voice-signaling VLAN network-policy profile applied on the interface.

• You cannot configure static secure MAC addresses on an interface that has a network-policy profile.

• You cannot configure a network-policy profile on a private-VLAN port.

• For wired location to function, you must first enter the ip device tracking global configuration

command.
