Abstract: Techniques are described for identifying destinations in a virtual network by defining virtual entities such as a port profile as the destination for network policies, such as redirect or span to be a logical set of ports (i.e., ports belonging to a port-profile or a port group) where the members of the set of ports may be added/removed dynamically without requiring any changes to the network policy. Further, a network administrator (or other user) may predefine the destinations for a network policy even before some or all of the destinations are active on a given virtualized system. In such cases, the network policies may go into effect when the required entities become available.

Abstract: A method of establishing and maintaining a consistent configuration state of a first processor, running on a first version of operating software, and a second processor, running on a second version of operating software, is described. The method involves determining a current configuration state of the first processor, where the configuration state comprises a list of configuration commands. The method also involves performing a syntax check for each command in the current configuration, using the second processor and the second version of operating software, with the syntax check resulting in a pass or a fail result. For every command which results in a fail result, an entry is added to a mismatched configuration list (MCL). Embodiments of this invention can be utilized to keep the configurations consistent during an upgrade or downgrade of the operating software.
