Method and apparatus for router port configuration
View Patent ↗A method and apparatus for selectively configuring, in a router, physical ports to either a Wide Area Network (WAN) or a Local Area Network (LAN). Method steps include receiving a message to configure a physical port for use with either the LAN or WAN; associating, in response to receiving the message, a set of mapping assignments for using the physical port to access the network; and implementing the mapping assignments, in response to associating the mapping assignments, to configure the physical port for coupling to the network.
1. A method of configuring, in a router having a LAN interface and a WAN interface, a physical port for coupling to a network, said method comprising:
receiving a message to configure said physical port for use with said network;
associating, responsive to receiving said message, a set of mapping assignments for using said physical port to access said network; and
implementing said mapping assignments, responsive to associating said mapping assignments, to configure said physical port for coupling to said network,
wherein said implementing step selectively controls whether said physical port is coupled to the LAN interface or the WAN interface.
2. The method of claim 1 , further comprising:
storing said mapping assignments.
3. The method of claim 1 wherein said network is a Wide Area Network (WAN).
4. The method of claim 1 wherein said network is a Local Area Network (LAN).
5. The method of claim 1 wherein said network is a Local Area Network (LAN) prior to said step of implementing and is a Wide Area Network (WAN) after said step of implementing.
6. The method of claim 1 wherein said message is implemented using an Simple Network Management Protocol (SNMP) SET command.
7. The method of claim 1 wherein said message is implemented using HyperText Transfer Protocol (HTTP) data.
8. The method of claim 1 wherein said message is created after detecting at least one hardware switch setting change.
9. The method of claim 1 wherein said message is implemented using a router proprietary command message.
10. A router having a physical port for coupling to a network and further having a LAN interface and a WAN interface, said router comprising:
means for receiving a message to configure said physical port for use with said network;
means for associating, responsive to receiving said message, a set of mapping assignments for using said physical port to access said network; and
means for implementing said mapping assignments, responsive to associating said mapping assignments, to configure said physical port for coupling to said network,
wherein said implementing means selectively controls whether said physical port is coupled to the LAN interface or the WAN interface.
11. A router comprising:
processor, memory, and support circuitry having a WAN/LAN port manager;
a LAN interface;
a WAN interface; and
a plurality of physical ports selectively connectable to said LAN interface or said WAN interface,
wherein said WAN/LAN port manager selectively controls whether each of said plurality of physical ports is physically coupled to said LAN interface or said WAN interface responsive to a configuration message and prior to a receipt of a corresponding packet to be routed by the router.
12. The method of claim 1 , wherein said implementing step changes the physical port from a secure type physical port to a non-secure type physical port or from the non-secure type physical port to the secure type physical port.
13. The router of claim 10 , wherein said implementing means changes the physical port from a secure type physical port to a non-secure type physical port or from the non-secure type physical port to the secure type physical port.
14. The method of claim 1 , wherein said implementing step changes the physical port from a WAN type physical port to a LAN type physical port or from the LAN type physical port to the WAN type physical port.
15. The router of claim 10 , wherein said implementing means changes the physical port from a WAN type physical port to a LAN type physical port or from the LAN type physical port to the WAN type physical port.
16. The method of claim 1 , wherein said implementing step alters an initial designation of the physical port by a manufacturer of the router as one of a LAN type port or a WAN type port to one of the WAN type port or the LAN type port, respectively.
17. The router of claim 10 , wherein said implementing means alters an initial designation of the physical port by a manufacturer of the router as one of a LAN type port or a WAN type port to one of the WAN type port or the LAN type port, respectively.
