Table 15-6. The load-balance Commands and Port Channel Types Configuration Commands Default (IP 5-tuple) load-balance ip-selection 3-tuple load-balance ip-selection mac load-balance ip-selection 3-tuple load-balance ip-selection mac load-balance ip-selection packet-based load-balance ip-selection packet-based load-balance ip-selection mac Switched IP Traffic IP 5-tuple (lower 32 bits) IP 3-tuple (lower 32 bits) MAC-based MAC-based Packet based: IPV4 No distribution: IPV6 MAC-based Routed IP Traffic (IPv4 only) IP 5-tuple IP 3-tuple IP 5-tuple IP 3-tuple Packet-based Packet-based Switched Non-IP Traffic MAC-based MAC-based MAC-based MAC-based MAC-based MAC-based C-Series and S-Series load-balancing For LAG hashing on C-Series and S-Series, the source IP, destination IP, source TCP/UDP port, and destination TCP/UDP port are used for hash computation by default. For packets without a Layer 3 header, FTOS automatically uses load-balance mac source-dest-mac. IP hashing or MAC hashing should not be configured at the same time. If you configure an IP and MAC hashing scheme at the same time, the MAC hashing scheme takes precedence over the IP hashing scheme. To change the IP traffic load balancing default on the C-Series and S-Series, use the following command: Command Syntax [no] load-balance {ip-selection [dest-ip | source-ip]} | {mac [dest-mac | source-dest-mac | source-mac]} | {tcp-udp enable} Command Mode Purpose CONFIGURATION Replace the default IP 4-tuple method of balancing traffic over a port channel. You can select one, two, or all three of the following basic hash methods ip-selection [dest-ip | source-ip]-Distribute IP traffic based on IP destination or source address. mac [dest-mac | source-dest-mac | source-mac]-Distribute IPV4 traffic based on the destination or source MAC address, or both, along with the VLAN, Ethertype, source module ID and source port ID. tcp-udp enable-Distribute traffic based on TCP/UDP source and destination ports. 304 | Interfaces
