How do I configure VRRP load balancing on an S series switch

32

To configure VRRP load balancing on an S series switch (except the S1700), see section "Typical Reliability Configuration" at S1720&S2700&S3700&S5700&S6700&S7700&S9700 Typical Configuration Examples. The configuration method for the S9300 is the same as that for other switch models.

S series switches (except the S1700) use a per-flow load balancing mechanism, which ensures that frames of the same data flow are forwarded on the same physical link, and different data flows are forwarded on different physical links. You can configure common load balancing mode to implement load balancing based on IP addresses or MAC addresses of packets. For L2, IP, and MPLS packets, you can also configure enhanced load balancing mode. Load balancing takes effect only for the outbound traffic. Therefore, load balancing modes can be different on the two ends of a link. 1. Commands for configuring common load balancing mode: [HUAWEI] interface Eth-Trunk 1 [HUAWEI-Eth-Trunk1] load-balance dst-mac 2. Commands for configuring enhanced load balancing mode: [HUAWEI] load-balance-profile a [HUAWEI-load-balance-profile-a] l2 field smac [HUAWEI-load-balance-profile-a] quit [HUAWEI] interface Eth-Trunk 1 [HUAWEI-Eth-Trunk1] load-balance enhanced profile a For configuration cases about common load balancing mode, see "Typical Ethernet Switching Configuration -Link Aggregation Configuration- Example for Configuring Link Aggregation in Manual Mode When Switches Are Directly Connected" in S1720&S2700&S3700&S5700&S6700&S7700&S9700 Typical Configuration Examples. The configuration cases of common load balancing are applicable to all S series switch models. The Sx700 series switch is used here as an example.

How to configure load balancing on an AC
Load balancing can evenly distribute AP traffic loads to ensure high bandwidth for each STA. The load balancing function applies to wireless networks with high user densities to ensure proper access of STAs. Depending on whether a load balancing group needs to be manually created, load balancing is classified into static and dynamic load balancing. For detailed principle description and configuration, see: V200R005: Configuring Load Balancing V200R006: Configuring Load Balancing

How to modify the ECMP load balancing mode of S series switch?
ECMP is applied to a network environment where multiple different links reach the same destination address.If you use traditional routing technology, packets destined for the destination address can only use one of the links, the other links in the backup state or invalid state, and in the dynamic routing environment to switch between each other takes some time. The ECMP can be used to multiple links in the network environment at the same time, not only increased the transmission bandwidth, and can be no delay without packet loss backup link data transmission.
