Provide a list of ports on a specific switch/hub whose MAC results should be ignored.Ports such as link/trunk ports that can not be distinguished from other user ports are examples.Each port number must be separated by a colon, pipe, or a space ':', '|', ' '.For example, 'Fa0/1: Fa1/23' or 'Fa0/1 Fa1/23' would be acceptable for some manufacturers switch types.
