In one embodiment, a system includes a first interface to receive a request to generate a user interface screen for a selected network device, a memory to store configuration data of the selected network device, a processor to generate, using the configuration data of the selected network device, a first user interface screen showing a graphical representation of an internal configuration of the selected network device in each of at least three different abstraction layers from a plurality of different abstraction layers, one of the at least three different abstraction layers including a physical layer showing a plurality of ports of the selected network device, and a second interface to send the first user interface screen for output to a display device. Related apparatus and methods are also described.

Methods and systems according to one or more embodiments establish communication across separate IP domains that are on the same layer 2 bridged domain. In an embodiment, a method includes receiving a configuration of a first IP address of a first node on a first side of a switch and a second IP address of a second node on a second side of the switch, wherein the first and second IP addresses are of different domains and are to be translated in each direction with respect to the switch, wherein the switch further comprises an integrated block adapted to do translation at line rate. Based on the configuration, the method also includes modifying, by the switch, packets of an applicable protocol in each direction so that the first and second IP addresses are changed for each domain such that either side of the switch acts as if an opposite side is on the same domain so that layer 2 communication is established.

Consistent with embodiments of the present invention, a method may be provided comprising receiving a search string corresponding to a desired node comprising a target parameter, a policy parameter, and a class parameter. The target parameter may be referenced with a target index table to determine which interfaces to search. The policy parameter may be referenced with a policy index table to determine a node-id of a policy node corresponding to the policy parameter. A level for the desired node may be determined based on the node-id. The class parameter may be referenced with the determined node-id with a class index table to access a bucket location. The desired node may then be searched for with the determined node-id at the determined level.
