Changes the hashing method for inter-packet-processor (inter-pp) HiGig links that are used to connect master and slave units in ICX 7450-48 devices.

dlb-internal-trunk-hash { inactivity-mode | spray-mode }
no dlb-internal-trunk-hash { inactivity-mode | spray-mode }

The hashing method is inactivity mode.

inactivity-mode
Specifies that the flow is set by the inactivity of traffic loading.
spray-mode
Specifies that the flow is set to receive new member assignments for every packet arrival in accordance with the traffic loading of each aggregate member.

Global configuration mode

The no form of this command restores the default hashing method.

Note: This command is supported only on ICX 7450-48 devices that have master and slave units.

Dynamic load balancing (DLB) enhances hash-based load balancing by taking into account the traffic loading in the network. The inter-pp HiGig links in ICX7450-48 devices use hash-based load balancing to distribute traffic evenly. You can configure the dlb-internal-trunk-hash command to change the hashing method.

Note: Spray mode may introduce out-of-order packet delivery.

The following example globally enables spray mode as the inter-pp links hashing method. 

ICX7450-48P Router(config)#dlb-internal-trunk-hash  spray-mode
