CONFIGURATION mode

Version 9.3(0.0) Introduced on the S6000 platform.

Flex hash uses the RTAG7 bins 2 and 3 (overlay bins). These bins must be enabled for Flex hash to be configured. These bins contain the source module and source port information. These bins are disabled by default in releases of Dell Networking OS earlier than Release 9.3.0.0. The default behavior of disabling of these bins occurs because of incorrect egress port information that would otherwise be displayed in the output of the diagnostic show command of show ip flow.

As a result, when load balancing of RRoCE packets using Flex hash is enabled, the show ip flow command is not functional. Similarly, when show ip flow command operates (ingress port based load balancing is disabled) the hashing of RRoCE packets is not operational.

Flex hash APIs do not mask out unwanted byte values after extraction of the data from the Layer 4 headers for the offset value.
