load-balance (E-Series)By default, for E-Series chassis, FTOS uses an IP 5-tuple to distribute IP traffic over members of a Port Channel as wellas equal cost paths. To designate another method to balance traffic over Port Channel members, use the load-balance command.E-SeriesSyntax 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 macParameters ip-selection 3-tupleEnter the keywords ip-selection 3-tuple to distribute IPtraffic based on the following criteria:• IP source address• IP destination address• IP Protocol typeNOTE: For IPV6, only the first 32 bits (LSB) of IP SA and IP DA areused for hash generation.ip-selectionpacket-basedEnter the keywords ip-selection packet-based todistribute IPV4 traffic based on the IP Identification field in the IPV4header. This option does not affect IPV6 traffic; that is, IPV6 traffic isnot distributed when this command is executed.NOTE: Hash-based load-balancing on MPLS does not work whenpacket-based hashing (load-balance ip-selectionpacket-based) is enabled.mac Enter the keyword mac to distribute traffic based on the following:• MAC source address• MAC destination addressDefaults IP 5-tuple (IP SA, IP DA, IP Protocol Type, Source Port and Destination Port)Command Modes CONFIGURATIONCommand History Version 8.1.1.0 Introduced on the E-Series ExaScale.Version 6.1.1.0 Introduced on the E-Series.UsageInformationBy default, FTOS distributes incoming traffic based on a hash algorithm using the followingcriteria:799
