How does S series switch implement load balancing among equal-cost routes

An S series switch supports enhanced equal-cost multipath (ECMP) load balancing mode. This function mitigates the problem of unequal traffic distribution among equal-cost routes. If this problem still occurs, configure a traffic policy to redirect the traffic with the highest rate to the link with the lightest traffic.

Perform the following operations to configure a traffic policy:
1. Configure redirection.
[HUAWEI] traffic behavior test
[HUAWEI-behavior-test] redirect ip-nexthop 100.1.1.2
2. Configure traffic classifier based on basic ACL.
[HUAWEI] acl 2000
[HUAWEI-acl-basic-2000] rule 10 permit source 200.1.1.2 0
[HUAWEI-acl-basic-2000] quit
[HUAWEI] traffic classifier test
[HUAWEI-classifier-test] if-match acl 2000
3. Create a traffic policy and associate it with the created traffic classifier and behavior.
[HUAWEI] traffic policy test
[HUAWEI-trafficpolicy-test] classifier test behavior test
4. Apply the traffic policy to the inbound direction of an interface.
[HUAWEI] interface GigabitEthernet 1/0/1
[HUAWEI-GigabitEthernet1/0/1] traffic-policy test inbound
