  • On-line switch diagnostics
    Patent number: 6487208
    Abstract: In a computer network system that includes a multiplicity of nodes interconnected by a network of switches, each switch having multiple ports, a method for testing one of the switches includes assigning a respective one of the nodes to each of a plurality of the ports of the switch being tested. The network is configured so that the switch being tested is substantially isolated from data flow from and to the nodes in the network that are not assigned to the ports of the switch. Data are conveyed at a controlled rate between two or more of the assigned nodes through the respective ports, and behavior of the switch is observed in response to the data being conveyed.
