headers for the offset value.
2. Use the load-balance flexhash command to specify whether IPv4 or IPv6 packets must be
subjected to 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.

Configuring Fast Boot and LACP Fast Switchover
Configure the optimized booting time functionality by performing the following steps. This procedure is
supported on the platform.
1.
Enable the system to restart with optimized booting-time functionality enabled.
CONFIGURATION mode
CONFIGURATION mode
Dell(conf)#reload-type fastboot
2. Configure fast boot on a port-channel on both the nodes that are members of a port-channel in
order to enable the physical ports to be aggregated faster. You can configure the optimal switchover
functionality for LACP even if you do not enable the fast boot mode on the system. This command
applies to dynamic port-channel interfaces only. When applied on a static port-channel, this
command has no effect. If you configure the optimized booting-time capability and perform a reload
of the system, the LACP application sends PDUs across all the active LACP links immediately.

Optimizing the Boot Time
This functionality is supported on the platform.
You can reduce the booting time of an S6000 switch by using the fast boot feature. With the reduced
time that is taken to reboot the switch, upon a manually-initiated reload or an expected restart of the
device, there is minimal disruption in the traffic that is managed by the switch. Traffic outage is lowered
considerably (reduced to approximately 25 seconds in certain network deployments) when you enable
