In this chapter
This chapter describes the stateful flow management feature.
See DN-1227 for more details on stateful flow management.
Note: This chapter only applies to NT200A02 running on the 2 × 40 Gbit/s FM image or on the
8 × 10 Gbit/s FM image, and to the NT100A01 running on the
4 × 25/10 Gbit/s FM1 image or on the 4 × 10/1 Gbit/s FM1 image.
Hash fundamentals
Stateful flow management is SHA-1 hash-based, with configurable hash key elements. Stateful flow management generates a 128-bit hash value as a flow signature.
The probability of a flow signature collision is extremely low and can be disregarded.
