Parameters Defaults Command Modes Command History Usage Information ip-selection 3-tuple ip-selection packet-based mac Enter the keywords ip-selection 3-tuple to distribute IP traffic based on the following criteria: • IP source address • IP destination address • IP Protocol type Note: For IPV6, only the first 32 bits (LSB) of IP SA and IP DA are used for hash generation. Enter the keywords ip-selection packet-based to distribute IPV4 traffic based on the IP Identification field in the IPV4 header. This option does not affect IPV6 traffic; that is, IPV6 traffic is not distributed when this command is executed. Note: Hash-based load-balancing on MPLS does not work when packet-based hashing (load-balance ip-selection packet-based) is enabled. Enter the keyword mac to distribute traffic based on the following: • MAC source address, and • MAC destination address IP 5-tuple (IP SA, IP DA, IP Protocol Type, Source Port and Destination Port) CONFIGURATION Version 8.1.1.0 Version 6.1.1.0 Introduced on E-Series ExaScale Introduced for E-Series By default, FTOS distributes incoming traffic based on a hash algorithm using the following criteria: • IP source address • IP destination address • IP 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. The table below lists the load balance command options and how the command combinations effect the distribution of traffic. Table 24-3.
