Service Manual

You can cause the system to include the elds present at the osets that you dene (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 1 offset2 2
reload-type fastboot
Restart the system with optimized booting-time functionality enabled. When you restart the device in fast boot mode, trac
disruption is reduced signicantly and the system operations to service the data trac are restored in a seamless way.
C9000 Series
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.

Command History
This guide is platform-specic. For command information about other platforms, refer to the relevant Dell
Networking OS Command Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.x.x.x Introduced on the C9000.
9.3(0.0) Added support for the fastboot parameter for S6000 platform.
Usage Information
You can congure 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 trac that is serviced by the
switch is minimized. Trac 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 trac loss, subscriber sessions are processed and preserved in an eective and seamless way.
lacp fast-switchover
Cause the physical ports to be aggregated faster by conguring this capability in a port-channel on both the nodes that are members
of a port-channel.
Syntax
lacp fast-switchover
To disable the capability of faster aggregation of the member ports of a LAG or a port-channel bundle, use
the no version of this command.
