Command
History
Version 9.2.1.0 Introduced on the Z9500 switch.
Version 9.3.0.0 Introduced on the S6000 platform
Usage
Information 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 ip flow
command.
When you enable the load balancing of RRoCE packets using Flex hash, the
show
ip flow
command is disabled. Similarly, when the
show ip flow
command is
enabled (ingress port based load balancing is disabled), the hashing of RRoCE
packets is disabled.
Flex hash APIs do not mask out unwanted byte values after extraction of the data
from the Layer 4 headers for the offset value.
