History
Usage Flex hash uses the RTAG7 bins 2 and 3 (overlay bins). These bins must be enabled
Information 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.
Example
Dell#load-balance ingress-port enable
load-balance flexhash
Specify the parameters for the Flex Hash mechanism, such as whether IPv4 or IPv6 packets must be
subject to Flex Hash functionality, a unique protocol number, the offset of hash fields from the start of
