Load balance trac
You can use hashing to load balance trac across the member interfaces of a port-channel. Load balancing uses source and destination
packet information to distribute trac 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 congure 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 trac 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 conguration.
– 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.
Congure 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 trac on port-channels. If you do not obtain even
trac distribution, use the hash-algorithm command to select the hash scheme for LAG. Rotate or shift the L2-bit LAG hash until the
desired trac 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
Congure interface ranges
Bulk interface conguration allows you apply the same conguration to multiple interfaces - either physical or logical, or to display their
current conguration. You can also create multiple logical interfaces in bulk. An interface range is a set of interfaces to which you can apply
the same command.
