On the E-Series, to change the 5-tuple default to 3-tuple, MAC, or packet-based, use the following
command in CONFIGURATION mode:
Command Syntax
[ no ] load-balance [ ip-selection
{ 3-tuple | packet-based }] [ mac ]
For details on the
To distribute IP traffic over an E-Series port channel member, FTOS uses the 5-tuple IP default. The
5-tuple and the 3-tuple hash use the following keys:
Table 20-6. 5-tuple and 3-tuple Keys
Keys
IP source address (lower 32 bits)
IP destination address (lower 32 bits)
Protocol type
TCP/UDP source port
TCP/UDP destination port
Note: For IPV6, only the first 32 bits (LSB) of IP Source Address and IP Destination Address are used for
hash generation.
Figure 20-18 shows the configuration and show command for packet-based hashing on the E-Series.
Figure 20-18. Command example:
FTOS(conf)#load-balance ip-selection packet-based
FTOS#show running-config | grep load
load-balance ip-selection packet-based
FTOS#

Purpose
To designate a method to balance traffic over a port
channel. By default, IP 5-tuple is used to distribute
traffic over members port channel.

and the MAC destination address.
