In which views can IPSG be enabled on S series switches
IPSG can be enabled on an S series switch (except the S1700) in an interface or a VLAN view. Interface views include the Ethernet interface view, GE interface view, 40GE interface view, XGE interface view, 100GE interface view, Eth-Trunk interface view, and port group view. Example 1: Enable IPSG in the GE0/0/1 view. [HUAWEI] interface gigabitethernet 0/0/1 [HUAWEI-GigabitEthernet0/0/1] ip source check user-bind enable Example 2: Enable IPSG in the VLAN 100 view. [HUAWEI] vlan 100 [HUAWEI-vlan100] ip source check user-bind enable

How to configure the Eth-Trunk hash mode on S series switches
You can run the load-balance command to configure the Eth-Trunk hash mode on S series switches (except the S1700).

How to configure load balancing for the Eth-Trunk on S series switches
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.
