On the E-Series, to change the 5-tuple default to 3-tuple, MAC, or packet-based, use the following
command in CONFIGURATION mode:
For details on the
load-balance
command, see the IP Routing chapter of the FTOS Command Reference .
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:
Figure 20-18 shows the configuration and show command for packet-based hashing on the E-Series.
Figure 20-18. Command example:
load-balance ip-selection packet-based
The
load-balance packet based
command can co-exist with
load balance mac
command to achieve the
functionality shown in Table 20-7 .

CONFIGURATION 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.
ip-selection 3-tuple
—Distribute IP traffic based on IP
source address, IP destination address, and IP protocol type.
ip-selection packet-based
—Distribute IPV4 traffic
based on the IP Identification field in the IPV4 header.
mac
—Distribute traffic based on the MAC source address,
and the MAC destination address.
See Table 20-7 for more information.
Table 20-6. 5-tuple and 3-tuple Keys
Keys 5-tuple 3-tuple
IP source address (lower 32 bits) X X
IP destination address (lower 32 bits) X X
Protocol type X X
TCP/UDP source port X
TCP/UDP destination port X
Note: For IPV6, only the first 32 bits (LSB) of IP Source Address and IP Destination Address are used for
hash generation.
