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 19-16 shows the configuration and show command for packet-based hashing on the E-Series.
Figure 19-16. 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 19-5.
IPv4, IPv6, and non-IP traffic handling on the E-Series
The table below presents the combinations of the load-balance command and their effect on traffic types.

Note: For IPV6, only the first 32 bits (LSB) of IP Source Address and IP Destination Address are used for
hash generation.
