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.
Example
Dell(conf)# load-balance flexhash ipv4 ip-proto 1 desc offset1

reload-type fastboot
Restart the system with optimized booting-time functionality enabled. When you restart the device in fast
boot mode, traffic disruption is reduced significantly and the system operations to service the data traffic
are restored in a seamless way. This command is supported on the S6000 platform.
Syntax
reload-type fastboot
Parameters
fastboot
Enable the system to restart the next time with the optimized
booting-time capability
Defaults
By default, the device reloads in Jumpstart or BMP mode.

Version 9.3(0.0)
Added support for the
fastboot
parameter for S6000
platform.
Usage
Information
You can configure an optimization technique to reduce the booting time of an
S6000 Switch. This mechanism is also called fast boot. With the reduced time that
is taken to reboot the switch, upon a manually-initiated reload or an expected
restart of the device, the disruption in traffic that is serviced by the switch is
minimized. Traffic outage is lowered considerably (reduced to approximately 25
seconds in certain network deployments) when you enable this optimization
method for booting of the device. By reducing the duration of traffic loss,
subscriber sessions are processed and preserved in an effective and seamless way.
