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. - 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. - 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 Change hash algorithm The load-balancing command selects the hash criteria applied to load balancing of traffic on port-channels. If you do not obtain even traffic distribution, use the hash-algorithm command to select the hash scheme for LAG. Rotate or shift the L2-bit LAG hash until the desired traffic distribution is achieved. • Change the default (0) to another algorithm and apply it to LAG hashing in CONFIGURATION mode. hash-algorithm lag {crc | xor | random} Change hash algorithm OS10(config)# hash-algorithm lag crc Configure interface ranges Bulk interface configuration allows you to apply the same configuration to multiple physical or logical interfaces, or to display their current configuration. An interface range is a set of interfaces that you apply the same command to. Interfaces 93
