1. A network switch system comprising:
- at least one source port for receiving a packet from a source;
at least one destination port as a destination for the packet;
at least one processing unit coupled to a memory storage device; and
program instructions, stored on the memory storage device for execution by the at least one processing unit to;
detect that a first host computer is removed from a first predetermined physical location of a circuit, said first host computer associated with a switch policy comprising simple network management protocol simple network protocol traps, a first quality of access level, a first quality of service level and a first access control list;
detect that a second host computer, different from the first host computer, is installed into a second predetermined physical location of the circuit different from the first predetermined physical location of the first host computer;
provide an adaptive change of at least one switch configuration by migrating said switch policy associated with the first host computer to the second host computer located in the second predetermined physical location, wherein said second host computer receives and becomes associated with said switch policy comprising the simple network management protocol, the simple network protocol traps, the first quality of access level, the first quality of service level, and the first access control list; and
verify the migrated switch policy against the at least one switch configuration by identifying MAC address information corresponding to the second physical location of the circuit.

Abstract
An improved system and method for network switching that provides the ability to automatically and seamlessly migrate policies for network hosts under certain conditions to local or remote switch ports. The improved switch automatically migrates switch policies for virtual and physical hosts from a source port to a destination port when hosts have been physically moved or replaced. For elements that have failed, the improved switch also migrates host network policies for both physical hosts and virtual machines when the old host network policy will maintain serviceability of the element when applied to the new port.

4. A method for operating a computer network communications device comprising:
-
detecting a host computer of a server farm is removed from a first predetermined physical location of a circuit, said first host computer in communication with a network switch having a switch policy comprising simple network management protocol, simple network protocol traps, a first quality of access level, a first quality of service level and a first access control list; detecting a second host computer, different from the first computer, of the server farm is installed into a second predetermined physical location, different from the first predetermined location, of the circuit; providing, by the network switch, an adaptive change of a switch configuration of the network switch by migrating said switch policy from the first host computer to the second host computer located in the second predetermined physical location, said second host computer, receiving and becoming associated with said switch policy comprising the simple network management protocol, the simple network protocol traps, the first quality of access level, the first quality of service level, and the first access control list, migrating a host network policy to the second host computer located in the second predetermined physical location, and verifying the migrated switch policy against the switch configuration by identifying MAC address information corresponding to the second physical location of the circuit. - View Dependent Claims (5, 6, 7)
