Claim 13:
14. A network system, comprising:
a second network device comprising a second port and configured to send first information indicating that a second port status of the second port is a second state, wherein the second state is different from an UP state;
a first network device coupled to the second network device and comprising a first port and configured to:
determine whether a first port status of the first port is switchable from a first state to an UP state, wherein the first network device comprises the first port, wherein the first state is different from the UP state, and wherein the UP state is a state in which a port can communicate with another network device;
receive the first information from the second network device; and
switch, based on the first port status and the second port status, a third port status of a port from either the first port or the second port according to a delay policy, wherein the third port status indicates the UP state,. wherein the delay policy comprises skipping a delay state of a port from either the first port or the second port when another port from either the first port or the second port is in the delay state, and wherein the delay state is a state of switching to the UP state after waiting for a preset period of time; and

an access side device coupled to the first network device and the second network device and configured to:
be dual-homed to the first network device and the second network device; and
communicate with the first network device and with the second network device.
