9.9(0.0) Introduced on the C9010.
9.3(0.0) Introduced on the S6000.
Usage
Information
You can configure the optimal switchover functionality for LACP even if you do not enable the fast boot
mode on the system. You must configure the long timeout mechanism for the LACP session to enable the
fast boot capability to operate properly. 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.

show lacp — displays the LACP configuration.
load-balance flexhash
Specify the parameters for the Flex Hash mechanism, such as whether IPv4 or IPv6 packets must be subject to 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. This utility is supported on the platform.
Syntax
load-balance flexhash ipv4/ipv6 ip-proto <protocol number> <description
string> offset1 <offset1 value> [offset2 <offset2 value>]
To disable the Flex hash settings, use the no load-balance flexhash ipv4/ipv6 ip-proto
protocol number command.
Parameters
ipv4 Denotes whether Flex Hash needs to be enabled for IPv4 packets.
ipv6 Denotes whether Flex Hash needs to be enabled for IPv6 packets.
protocol number Represents the Outer IPv4 protocol field in case of IPv4 packets, and the Outer
IPv6 next header field in case of 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 present. Duplicate flex hash configuration is not possible. To change an
existing flex hash configuration, you must delete the existing flex hash attribute
and configure the flex attribute afresh.
description
string
A description string is followed by the protocol number to enable you to associate
the protocol number with the protocol name in an easily-identifiable way. For
example, for a protocol number of 254, you can specify the description as RRoCE.
offset1 value Specify the byte offset from the start of the L4 header from which the 2-byte data
is extracted and be used in hash computation. You must enter the offset as an
even number. The offset range is 0 – 30 bytes from start of L4 header.
offset2 value (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 – 30 bytes from start of L4 header.
Default None
