The following example shows the configuration and show command for packet-based hashing on the
E-Series.
FTOS(conf)#load-balance ip-selection packet-based
FTOS#show running-config | grep load
load-balance ip-selection packet-based
FTOS#
The load-balance packet based command can co-exist with load balance mac command to achieve the
functionality shown in Table 23-5, "The load-balance Commands and Port Channel Types," in Interfaces.
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.
C-Series and S-Series load-balancing
For LAG hashing on C-Series and S-Series, the source IP, destination IP, source TCP/UDP port, and
destination TCP/UDP port are used for hash computation by default. For packets without a Layer 3 header,
FTOS automatically uses
load-balance mac source-dest-mac.
IP hashing or MAC hashing should not be configured at the same time. If you configure an IP and MAC
hashing scheme at the same time, the MAC hashing scheme takes precedence over the IP hashing scheme.
Note: For IPV6, only the first 32 bits (LSB) of IP Source Address and IP Destination Address are used for hash generation.
