Method and apparatus for determining a network topology based on Spanning-tree-Algorithm-designated ports

摘要

A method of determining a network topology based on Spanning-tree-Algorithm-designated ports is disclosed. A first Spanning-tree-Algorithm-designated port that is associated with a network interface of a first network device is determined. A second Spanning-tree-Algorithm-designated port that is associated with a network interface of a second network device is determined. Based on the first designated port and the second designated port, it is determined whether the network interface of the first network device is connected to the network interface of the second network device.
