System and method of maintaining coherent and synchronized address tables on all switches in a software stacking configuration

摘要

Methods and systems provide for identical address tables in a software stack of switches. The software stack is maintained by organizing the switches into the software stack. Each switch in the software has a corresponding address table and one or more ports. Each address table maps one or more packet addresses to a port in the software stack. Synchronization of the address tables is initiated and enables significant performance improvements. Synchronization is initiated by populating a command buffer of a first switch in the stack with one or more address table commands. The buffer is distributed to remaining switches in the stack.
