摘要

In one example, a network management system discovers a plurality of network devices behind a network address translation device, such as a firewall. The network management system may receive a model of a seed network device, generate a first activation configuration and commit the first activation configuration on the seed network device. The network management system may connect to the seed network device and discover neighboring devices from information in the seed network device. The network management system may connect to the neighboring devices, automatically create a model of the neighboring network devices, generate s activation configurations for the neighboring network devices and commit the activation configurations on the neighboring network devices. The network management system may iterative perform these steps until it discovers all the discoverable network devices behind the network address translation device.

說明書

Network management system 10 also includes configuration database 40. Configuration database 40 generally includes information describing managed network devices, e.g., network devices 14. For example, configuration database 40 may include information indicating device identifiers (such as MAC and/or IP addresses), device type, device vendor, devices species (e.g., router, switch, bridge, hub, etc.), or the like. Configuration database 40 also stores current configuration information for the managed devices (e.g., network devices 14).

Although user interface 36 is described as allowing administrators 12 (FIG. 1) to interact with network management system 10, other interfaces may be used in other examples. For example, network management system 10 may include a representational state transfer (REST) administrator (not shown) that may act as an interface to another device, by which administrators 12 may configure network management system 10. Likewise, administrators 12 may configure network devices 14 by interacting with network management system 10 through the REST administrator.
