| Abstract: |
A method of automatically determining an attached device type for a multi-port LAN switch, and configuring the port based on the attached device type is provided. The method comprises setting a LAN switch port to a port mode, and determining, during a first period of time, whether an attached device is attempting to insert at the LAN switch port. If the attached device is attempting to insert during this first period of time, the method continues by configuring the LAN switch port in the port mode. If the attached device is not attempting to insert during the first period of time, the method continue by setting the LAN switch port in an adapter mode, transmitting a test frame to the attached device, and then determining, during a second period of time, whether a response frame is received from the attached device. If a response frame is received during the second period of time, the method further includes configuring the LAN switch port in the adapter mode.

What is claimed is:
1. A method of configuring a port of a multi-port LAN switch based on an attached device type for a multi-port LAN switch having one or more attached devices, the method comprising the steps of:
- setting a port of the multi-port LAN switch to operate as a concentrator, and determining, during a first period of time, whether an attached device is attempting to insert into a network at the multi-port LAN switch port;
- if the attached device is attempting to insert during the first period of time, configuring the port of the multi-port LAN switch to operate as a concentrator;
- if the attached device is not attempting to insert during the first period of time, setting the port of the multi-port LAN switch to operate as a network adapter, transmitting an insert signal to the attached device, and determining, during a second period of time, whether a response signal is received from the attached device; and
- if a response signal is received during the second period of time, configuring the port of the multi-port LAN switch to operate as a network adapter.
