Command History Version 8.3.5.0 Version 7.6.1.0 Version 7.5.1.0 Introduced on the S55. Added support for S-Series Introduced on C-Series Usage Information By default, FTOS distributes incoming traffic based on a hash algorithm using the following criteria: • IP source address • IP destination address • TCP/UDP source port • TCP/UDP destination port load-balance (E-Series) e By default, for E-Series chassis, FTOS uses an IP 5-tuple to distribute IP traffic over members of a Port Channel as well as equal cost paths. To designate another method to balance traffic over Port Channel members, use the load-balance command. Syntax load-balance [ip-selection 3-tuple | ip-selection packet-based] [mac] To return to the default setting (IP 5-tuple), use one of the following commands: • no load-balance ip-selection 3-tuple • no load-balance ip-selection packet-based • no load-balance mac Parameters 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.
