Balancing may be applied to IPv4, switched IPv6, and non-IP traffic. For these traffic types, the IP-header-based hash and MAC-based hash may be applied to packets by using the following methods. Table 23-3. Hash Methods as Applied to Port Channel Types Hash (Header Based) 5-tuple 3-tuple Packet-based MAC source address (SA) and destination address (DA) Layer 2 Port Channel X X X X Layer 3 Port Channel X X X 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. Refer to Table 23-5, "The load-balance Commands and Port Channel Types," in Interfaces for more information. For details on the load-balance command, refer to 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 23-4. 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 Interfaces | 431
