A method and system for enforcing network topology. The method includes receiving, at a first port on a first switch, a second role associated with a second switch, where the second switch is connected to the first switch using the first port, and where the first switch is associated with a first role. The method further includes making a first determination, using the first role, the second role, and a network topology policy, that the first switch should not be connected to the second switch. Sending, in response to the first determination, a first alert to an alert recipient, where the first alert specifies that the first switch is improperly connected to the second switch.

Method and system for network topology enforcement

A method for determining that a defect applies to a network device that includes receiving, at a monitoring module, network device information from the network device. The network device information includes state information for the network device and does not include hardware and software version information. The method includes storing, in a network device database, the network device information from the network device and receiving, at the monitoring module, defect information about a defect. The defect information includes network device criteria specifying what state information is required for a network device to be affected by the defect. The method includes storing the defect information in a defect database, determining that the defect applies to the network device based on analyzing the network device information and the defect information from their respective databases, and, based on the determination, informing a defect alert recipient that the defect applies to the network device.

Method and system for monitoring and correcting defects of a network device

A method for executing a command line interface (CLI) command by receiving a hyper text transport protocol (HTTP) comprising the CLI command from a controller, extracting the CLI command from the HTTP request, and executing, by a network device, the CLI command to generate a populated model comprising results generated from executing the CLI command. The method also executes the CLI command by converting the populated model into a JSON format using a JSON engine to obtain a JSON result; encapsulating the JSON result in a JSON Remote Procedure Call (RPC), and transmitting the JSON RPC as a HTTP response to the controller.

Method and system for using JSON with a CLI for managing network devices

A non-transitory computer readable medium includes instructions, which, when executed by a processor, perform a method on a network device. The method includes receiving, from a configuration server, a master configuration script that includes an instruction set, a network topology for network devices, and a dictionary. The dictionary includes network device specific configuration scripts for the network devices. The method also includes executing the instruction set on the network device to configure the network device. Executing the instruction set includes obtaining link layer discovery protocol (LLDP) information for the network device, determining a most common interface (MCI) connected to the network device using the LLDP information, determining a network device identity using the MCI, obtaining, from the dictionary, a network device specific configuration script for the network device based on the network device identity, and executing the network device specific configuration script to configure the network device.

Method and system for auto-provisioning network devices in a data center using network device location in network topology

A method for configuring a switch. The method includes receiving a configuration request from a switch, where the configuration request includes switch neighbor information (SNI) for the switch and a Media Access Control (MAC) address for the switch, identifying a replacement entry including a second MAC address and the SNI. The method further includes, based on the identification obtaining configuration information associated with the replacement entry, where the configuration information specifies a configuration of a second switch associated with the second MAC address, generating a configuration script using the configuration information and sending the configuration script to the switch, where the configuration script is executed by the switch to configure the switch.
