Load balance trac

You can use hashing to load balance trac across the 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.

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 conguration. This option is not supported on S5148F-ON.

– 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. This option is not supported on S5148F-ON.

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.

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.

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 load balancing of trac 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 the

desired trac distribution is achieved.

• Change the default (0) to another algorithm and apply it to LAG hashing in CONFIGURATION mode.

Change hash algorithm

OS10(config)# hash-algorithm lag crc

Congure interface ranges

Bulk interface conguration allows you to apply the same conguration to multiple interfaces - either physical or logical, or to display their

current conguration. An interface range is a set of interfaces to which you can apply the same command.
