Abstract

In a computer network system, a mechanism is described for enabling system/network management system to operate in a network address translation environment. Embodiments of the invention allow users to define and specify logical identifiers for agents connecting to the system management network and wishing to communicate with a server layer in the network. The logical identifiers enable the server layer to resolve the addresses of connecting agents to the IP addresses stored and recognized by the server layer.
