Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Use hashing to load balance traffic across 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.
  • tcp-upd-selection [l4–destination-port | l4–source-port] — Uses the Layer 4 destination port or Layer 4 source port in the hash calculation.
  • 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 port or Layer 4 source port 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 port or Layer 4 source port 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.
