Dell Force10 S50P FTOS Configuration Guide FTOS 8.4.2.7 E-Series TeraScale, C- - Page 437

On the E-Series, to change the 5-tuple default to 3-tuple, MAC, or packet-based, use the following command in CONFIGURATION mode: Command Syntax [no] load-balance [ip-selection {3-tuple | packet-based}] [mac] Command Mode Purpose CONFIGURATION To designate a method to balance traffic over a port channel. By default, IP 5-tuple is used to distribute traffic over members port channel. ip-selection 3-tuple-Distribute IP traffic based on IP source address, IP destination address, and IP protocol type. ip-selection packet-based-Distribute IPV4 traffic based on the IP Identification field in the IPV4 header. mac-Distribute traffic based on the MAC source address, and the MAC destination address. See Table 20-7 for more information. 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. The 5-tuple and the 3-tuple hash use the following keys: Table 20-6. 5-tuple and 3-tuple Keys Keys IP source address (lower 32 bits) IP destination address (lower 32 bits) Protocol type TCP/UDP source port TCP/UDP destination port 5-tuple X X X X X 3-tuple X X X Note: For IPV6, only the first 32 bits (LSB) of IP Source Address and IP Destination Address are used for hash generation. Figure 20-18 shows the configuration and show command for packet-based hashing on the E-Series. Figure 20-18. Command example: load-balance ip-selection packet-based 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 20-7.
