Dell 9.7(0.0) manual Reload-type fastboot, C9000 Series

headers are not sufficient to distinguish the flows. Therefore, the fields in the L4 header are processed when hashing is performed for packets over LAG and ECMP links. The Flex Hash functionality enables you to configure a packet search key and matches packets based on the search key. When a packet matches the search key, two 16-bit hash fields are extracted from the start of the L4 header and provided as inputs (bins 2 and 3) for RTAG7 hash computation. You must specify the offset of hash fields from the start of the L4 header, which contains a flow identification field.

You can cause the system to include the fields present at the offsets that you define (from the start of the L4 header) as a part of LAG and ECMP computation. Also, you can specify whether the IPv4 or IPv6 packets must be operated with the Flex Hash mechanism.
