CloudEngine S3700, S5700, and S6700 V600R023C10 Configuration Guide - Ethernet Switching Configuration
Configuring a Dynamic Load Balancing Mode
Context
Traditional static load balancing cannot balance the usage of member links, leading to congestion or even packet discarding on some member links in scenarios involving a large amount of data flows. After the dynamic load balancing function is enabled, traffic of an Eth-Trunk is dynamically load balanced over its member links, ensuring evenly load balanced traffic.
Dynamic load balancing modes are supported only by the S6750-H.
Procedure
- Enter the system view.
system-view - Create a dynamic load balancing profile and enter the dynamic load balancing profile view, or enter the view of an existing dynamic load balancing profile.
load-balance profile dynamic profile-name
By default, the system defines a dynamic load balancing profile named default, which can be modified but not deleted.
- Configure a dynamic load balancing mode for an Eth-Trunk interface.
eth-trunk mode { spray | fixed | eligible [ flowlet-gap-time gap-time ] }
By default, the dynamic load balancing mode of an Eth-Trunk interface is eligible (a recommended mode), and the interval for sending packets in a flowlet is 1000 microseconds.
- Return to the system view.
quit - Enter the view of an Eth-Trunk interface.
interface eth-trunk trunk-id
- Apply the dynamic load balancing profile to the Eth-Trunk interface.
load-balance dynamic profile profile-name
By default, no dynamic load balancing profile is applied to an Eth-Trunk interface.
