A switching device comprises a plurality of switch cores, each switch core having a plurality of ports associated with the switch core. Each switch core is configured to perform ingress processing of a data frame using a local source port indicator corresponding to an ingress port selected from a first plurality of ports associated with the switch core. Ingress processing of a data frame includes applying a global target port indicator corresponding to an egress port selected from a second plurality of ports including ports associated with one or more other switch cores among the plurality of switch cores.
