Summary

Supervisor acceleration is one of the most significant features released in the 4.x code train. The capability to get “line-rate” throughput per flow is a drastic improvement over a 1-gigabit limit per flow. Leveraging the PISA to inspect traffic flows prior to the FWSM also increases throughput performance. Memory partitions, rule allocation, and ACL optimization help to make the best use of resources and grow as network requirements continue to grow. Understanding the intricacies of each of these features in this chapter will undoubtedly make you more successful in the design, implementation, and management of the FWSM and give you a better understanding of where the optimal placement of the FWSM should be in your network.
