Load balance traffic

You can use hashing to load balance traffic across the member interfaces of a port-channel. Load balancing uses source and destination packet information to distribute traffic over multiple interfaces when transferring data to a destination.

For packets without an L3 header, OS10 automatically uses the load-balancing mac—selection destination-mac command for hash algorithms by default.

When you configure an IP and MAC hashing scheme at the same time, the MAC hashing scheme takes precedence over the IP hashing scheme.

  • Select one or more methods of load balancing and replace the default IP 4-tuple method of balancing traffic over a port-channel in CONFIGURATION mode.
    OS10(config)# load-balancing
                                           ingress-port       Ingress port configurations
                                           tcp-udp-selection  TCP-UDP port for load-balancing configurations
                                           ip-selection       IPV4 load-balancing configurations
                                           ipv6-selection     IPV6 load-balancing configurations
                                           mac-selection      MAC load-balancing configurations
                                           
                                        
    • ingress-port [enable] — Enables the ingress port configuration. This option is not supported on S5148F-ON.
    • tcp-upd-selection [l4–destination-port | l4–source-port] — Uses the Layer 4 destination IP address, or Layer 4 source IP address in the hash calculation. This option is not supported on S5148F-ON.
    • ip-selection [destination-ip | source-ip | protocol | vlan-id | l4–destination-port | l4–source-port] — Uses the destination IP address, source IP address, protocol, VLAN ID, Layer 4 destination IP address, or Layer 4 source IP address in the hash calculation.
    • ipv6-selection [destination-ip | source-ip | protocol | vlan-id | l4–destination-port | l4–source-port] — Uses the destination IPv6 address, source IPv6 address, protocol, VLAN ID, Layer 4 destination IPv6 address, or Layer 4 source IPv6 address in the hash calculation.
    • mac—selection [destination-mac | source-mac] [ethertype | vlan-id] — Uses the destination MAC address or source MAC address, and ethertype, or VLAN ID in the hash calculation.
Configure load balancing
OS10(config)# load-balancing ip-selection destination-ip source-ip
