● 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.
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 traffic load balancing 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 you achieve the desired traffic distribution.
● 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.
You can use interface ranges for:
● Ethernet physical interfaces
● Port channels
● VLAN interfaces
A bulk configuration includes any non-existing interfaces in an interface range from the configuration.
You can configure a default VLAN only if the interface range being configured consists of only VLAN ports. When a
configuration in one of the VLAN ports fails, all the VLAN ports in the interface range are affected.
Create an interface range allowing other commands to be applied to that interface range using the interface range
command.
Configure range of Ethernet addresses and enable them
OS10(config)# interface range ethernet 1/1/1-1/1/5
OS10(conf-range-eth1/1/1-1/1/5)# no shutdown
