advertising.

a native VLAN mismatch is detected. This means that the native VLAN
information in the incoming frame does not match what the local device is

CDP Interface Settings
The Interface Settings page enables you to enable/disable CDP per port.
Notifications can also be triggered when there are conflicts with CDP neighbors.
The conflict can be Voice VLAN data, Native VLAN, or Duplex.
By setting these properties it is possible to select the types of information to be
provided to devices that support the LLDP protocol.
