Interfaces | 491• IP destination address• Protocol type• TCP/UDP source port• TCP/UDP destination portBalancing may be applied to IPv4, switched IPv6, and non-IP traffic. For these traffic types, theIP-header-based hash and MAC-based hash may be applied to packets by using the following methods.On the E-Series, to change the 5-tuple default to 3-tuple, MAC, or packet-based, use the followingcommand in CONFIGURATION mode:For details on the load-balance command, see the IP Routing chapter of the FTOS Command Reference.To distribute IP traffic over an E-Series port channel member, FTOS uses the 5-tuple IP default. The5-tuple and the 3-tuple hash use the following keys:Table 23-3.

By default, IP 5-tuple is used to distributetraffic over members port channel.ip-selection 3-tuple—Distribute IP traffic based on IPsource address, IP destination address, and IP protocol type.ip-selection packet-based—Distribute IPV4 traffic basedon the IP Identification field in the IPV4 header.mac—Distribute traffic based on the MAC source address,and the MAC destination address.See Table 23-1 for more information.Table 23-4. 5-tuple and 3-tuple KeysKeys 5-tuple 3-tupleIP source address (lower 32 bits) X XIP destination address (lower 32 bits) X XProtocol type X X
