Abstract
An embodiment of a network device includes a plurality of switch cores and a plurality of ports for receiving and transmitting data frames on a network disposed on a single integrated circuit, where switch core is coupled to a subset of the plurality of ports. The network device includes a deactivator configured to selectively deactivate at least a portion of one or more switch cores among the plurality of switch cores on the single integrated circuit, and the network device is configured to forward data frames among the plurality of ports based on a configuration of active portions of the plurality of switch cores. The deactivated portions may include ingress processing pipelines, egress processing pipelines, and/or entire switch cores. The portions of the switch cores to be deactivated may be dynamically be determined based on connectors of the integrated circuit.
