Abstract: Various exemplary embodiments relate to a network management system (NMS) and a method performed on the NMS including one or more of the following: receiving a notification of a new endpoint discovered in the network, the new endpoint representing an endpoint in a multi-chassis pair; determining that an address of the new endpoint conflicts with an address of a first existing endpoint of an existing multi-chassis pair, wherein the first existing endpoint is currently paired with a second existing endpoint; determining whether the new endpoint or the first existing endpoint is a proper endpoint of the existing multi-chassis pair; and when the new endpoint is the proper endpoint of the existing multi-chassis pair, updating the data representing the topology in the storage module to replace the first existing endpoint with the new endpoint as paired with the second existing endpoint.

Abstract: A system and method for substantially preventing firewall generated communication losses in regard to communications by authorized users in a managed computer network system is provided. The method comprises transmitting one or more status inquiry commands to at least one node in the managed computer network system, wherein the status inquiry command requests a first quantity of objects from the at least one node; receiving a non-zero quantity of objects response from the at least one node; and limiting communications through the firewall in the managed computer network system with the at least one node to a message size substantially equivalent to the received non-zero quantity of objects response from the at least one node, thereby substantially preventing firewall generated communication losses in the managed computer network system.
