Guidelines for Maximum Throughput

To achieve maximum throughput, we recommend the following:

• Use a load-balancing hash algorithm that is “symmetric,” meaning that packets from both directions will have the same hash and will be sent to the same threat defense in the Spanned EtherChannel. We recommend using the source and destination IP address (the default) or the source and destination port as the hashing algorithm.

• Use the same type of line cards when connecting the threat defenses to the switch so that hashing algorithms applied to all packets are the same.
