1. A communications network, comprising:
- a first node having a first port;
a second node having a second port, wherein the second port is connected to the first port by a communications link;
wherein;
the first node transmit a first identification message from the first port, the identification message addressed to an address, the identification message comprising only one frame;
the second node receives the identification message on the second port;
the second node logs the identification information; and
the second node delivers the identification information to an administrator, the administrator operable to determine that the first node and the second node are physically connected.

Abstract
A communications network is disclosed in which network nodes transmit messages between each other in order to determine which nodes are physically linked. The messages include information identifying the sending node and port. As messages are received by nodes, the information within the messages is logged. The logged information is collected by an administrator. The administrator uses the collected data to determine a network topography. The network topographies may be used to determine failures within the network.

10. A method for determining a network topography, comprising the steps of:
-
transmitting from a first port on a first node, an identification message, the identification message comprising only one frame and containing identification information;
receiving on a second port of a second node, the identification message;
logging the identification information;
delivering the logged identification information to an administrator;
determining a nearest neighbor for the first node, where the nearest neighbor has received an identification message from the first node, or the nearest neighbor has received an identification message from the first node. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An information handling system, comprising:
-
a first node having a first port, the first node operable to be connected in a computer network comprising a second node, the second node having a second port;
wherein the first node is operable to;
transmit a first message a first identification message, the first identification messaged addressed to an address, the first identification message comprising only one frame;
receive a second message on the first port, the second message addressed to the address, the second message comprising identification information about a second node in the communication network, the second node having a second port, the second message comprising only one frame;
log the identification information; and
deliver the identification information to an administrator, the administrator operable to determine that the first node and the second node are physically connected. - View Dependent Claims (19, 20)
