Load balance trac
Use hashing to load balance trac across member interfaces of a port-channel. Load balancing uses source and destination packet
information to distribute trac 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 congure 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 trac over a port-channel in
CONFIGURATION mode.

ingress-port Ingress port configurations
tcp-udp-selection TCP-UDP port for load-balancing configurations
ip-selection IPV4 load-balancing configurations

mac-selection MAC load-balancing configurations
– ingress-port [enable] — Enables the ingress port conguration.
– 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.
Congure 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 trac load balancing on port-channels. If you do not obtain even
trac 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 trac 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
