Abstract: Techniques for extended network configuration conversion and reconfiguration are described. A network controller proceeds through a set of extended network nodes in an extended network and reconfigures ports in at the various nodes from a first configuration to a second configuration while preventing network traffic looping and maintaining data and management traffic connection to the nodes during the reconfiguration.

Abstract: Stack switching detection may be provided. First, a request to connect to a server may be received by the server from a first network device. Then the server may send, in response to receiving the request, a query to the first network device for a serial number of any other network device connected to the first network device. The first network device may have a first serial number. The server may receive, from the first network device, a response to the query. The response may include a second serial number corresponding to a second network device connected to the first network device. Next, the server may determine, based on the response, that the first network device and the second network device comprise a stack unit. The server may then provision the stack unit by provisioning the first network device and provisioning the second network device through the first network device.
