Load-Balance Flexhash - Dell Z9500 Reference Manual

load-balance flexhash

Configure Flex hash operation, such as whether IPv4 or IPv6 packets are processed by the Flex hash
functionality, a unique protocol number, the offset of hash fields from the start of the L4 header to be
used for hash calculation, and a meaningful description to associate the protocol number with the name.

Flex Hash
Specifies that Flex hash must be enabled for IPv4 packet
processing.
Specifies that Flex hash must be enabled for IPv6 packet
processing.
The specified protocol number identifies the outer IPv4
protocol field in IPv4 packets and the outer IPv6 next-header
field in IPv6 packets.
The ipv4/ipv6 keyword and the IP protocol value are used
as keys to identify if a duplicate flex hash configuration is
already enabled. Duplicate flex-hash configuration is not
supported. To change an existing flex hash configuration,
you must delete the existing flex hash attribute and re-
configure the flex attribute.
Enter a text description to associate the protocol number
with the protocol name in an easily identifiable way. For
example, if the protocol number is 254, you can enter
RRoCE as the description.
Specify the byte offset from the start of the L4 header from
which the 2-byte data is extracted and used in hash
computation. You must enter the offset as an even number.
The offset range is 0 to 30 bytes from start of L4 header.
(Optional) Specify the additional 2 bytes that must be
extracted from the start of the L4 header to be used for hash
computation. You must enter the offset as an even number.
The offset range is 0 to 30 bytes from start of L4 header.
Introduced on the Z9500 switch.
Introduced on the S6000 platform.
