INTER-NETWORKING DEVICES FOR USE WITH PHYSICAL LAYER INFORMATION
First Claim
1. A system comprising:
- a plurality of switches coupled to one another via a plurality of network segments that make up a network;
a central bridge function configured to receive physical layer information related to the network, the physical layer information including information associating media access control (MAC) addresses of devices on the network with ports of the switches;
wherein the central bridge function is configured to determine a spanning tree for the network; and
wherein the central bridge function is configured to communicate information about the spanning tree to the plurality of switches;
wherein the switches are configured to use the information about the spanning tree determined by the central bridge function to configure the switch to carry out a bridging function performed by the plurality of switches.

Abstract
One exemplary embodiment is directed to an inter-networking device that performs at least one inter-networking function using physical layer information about the network of which the device is a part. Another exemplary embodiment is directed to capturing physical layer information about physical communication media that is attached to an inter-networking device. Another exemplary embodiment is directed to a technique for generating a spanning tree and/or forwarding database information for a plurality of switches in a network at a central location. The spanning tree and/or forwarding database information is generated at the central location using information including physical layer information about devices and physical communication media in the network. Another exemplary embodiment is directed to an ETHERNET physical layer device having integrated support for capturing physical layer information about the physical communication media connected to the ETHERNET physical layer device.
