1. A network device comprising:
- a chip configured to detect a loop caused by the network device in which a frame permanently circulates between the network device and at least one other network device;
a processor configured to control the network device to indicate a location of the network device in response to a detection of the loop;
a plurality of ports connectable to a network; and
a circuit configured to recognize a new connection to one of the ports, whereinthe chip is configured to perform a loop detecting process of detecting the loop iteratively at a first time interval, and perform the loop detecting process at a second time interval that is shorter than the first time interval for a predetermined time period from recognizing the new connection.

9. A method for specifying a location of a network device connected to a network, the method comprising:
-
detecting a loop caused by the network device in which a frame permanently circulates between the network device and at least one other network device; indicating, by the network device, location of the network device in response to a detection of the loop; and recognizing a new connection to one of a plurality of ports of the network device that are connectable to a network, wherein the detecting includes a loop detecting process of detecting the loop iteratively at a first time interval, and the loop detecting process is performed at a second time interval that is shorter than the first time interval for a predetermined time period from recognizing the new connection.
