Abstract

In an embodiment, an internetworking device is configured with compliance proxy logic that is configured for sending, to a compliance server, a request to determine whether the command conforms to one or more compliance policies, wherein the request includes the command; receiving a compliance response from the compliance server; in response to determining whether the compliance response indicates success, executing the command only when the compliance response indicates that the command conforms to the one or more compliance policies. Thus the device can determine actively whether a proposed user command or configuration change will violate established standards or policies, before the command or change is applied to the device.
