Configuring Load Balancing Mode

Configuring Per-packet Load Balancing

By default, Huawei NetEngine 8000 F's control and forwarding planes both work in per-flow load balancing mode. You can configure the commands shown in Table 1 to change the mode to per-packet.

**Table 1** Configuring per-packet load balancing
View	Command Format	Influence Scope	Description
System view	load-balance packet { slot slot-id \| all }	On the forwarding plane, this command takes effect only on MPLS packets on P nodes. On the control plane, this command takes effect on the IP packets and MPLS packets sent by CPU.	Configure the per-packet load balancing mode for packet forwarding.
Interface view	mpls l2vpn load-balance packet	Inbound LDP/SVC VLL traffic of the interface	Prerequisites: a LDP VLL or an SVC VLL has been configured on the corresponding interface and a tunnel policy has been configured for the L2VPN. If VLL FRR is enabled on the interface, this command takes effect on both primary and secondary PWs.
Eth-Trunk interface view	load-balance packet-all	Traffic sent by the interface on which the command is run	By default, Layer 3 Eth-Trunk interfaces perform per-flow load balancing based on IP addresses, and Layer 2 Eth-Trunk interfaces perform per-flow load balancing based on MAC addresses.

Configuring Per-flow Load Balancing

By default, Huawei NetEngine 8000 F's control and forwarding planes both work in per-flow load balancing mode. You can configure the commands shown in Table 2 to change the mode to per-flow if the mode has been changed to per-packet.

**Table 2** Configuring per-flow load balancing
View	Command Format	Influence Scope	Description
System view	load-balance flow { slot slot-id \| all } or undo load-balance packet { slot slot-id \| all }	On the forwarding plane, this command takes effect only on MPLS packets on P nodes. On the control plane, this command takes effect on the IP packets and MPLS packets sent by CPU.	Configure the per-flow load balancing mode for packet forwarding.
Interface view	undo mpls l2vpn load-balance packet	Inbound LDP/SVC VLL traffic of the interface	Prerequisites: a LDP VLL or an SVC VLL has been configured on the corresponding interface and a tunnel policy has been configured for the L2VPN. If VLL FRR is enabled on the interface, this command takes effect on both primary and secondary PWs.
Layer 3 Eth-Trunk interface view	load-balance src-dst-ip or undo load-balance	Traffic sent by the interface on which the command is run	By default, Layer 3 Eth-Trunk interfaces perform per-flow load balancing based on IP addresses.

Configuring Load Balancing on a BAS Interface

**Table 3** Configuring load balancing on a BAS interface
View	Command Format	Influence Scope
Eth-Trunk interface view	bas-load-balance { flow-mode \| user-mode \| real-flow-mode }	BAS user online traffic

Follow-up Procedure

Run the save command to save the current configuration to the configuration file when a set of configuration is finished and the expected functions have been achieved.
