6. Move the cursor to the Type column for the selected port and use the Space bar to select the

trunk type:

• LACP

• Trunk (the default type if you do not specify a type)

All ports in the same trunk group on the same switch must have the same Type (LACP or

Trunk.)

7. When you are finished assigning ports to the trunk group, press [Enter], then [S] (for Save)

and return to the Main Menu. (It is not necessary to reboot the switch.)

During the Save process, traffic on the ports configured for trunking is delayed for several

seconds. If the Spanning Tree Protocol is enabled, the delay may be up to 30 seconds.

8. Connect the trunked ports on the switch to the corresponding ports on the opposite device. If

you previously disabled any of the trunked ports on the switch, enable them now. (See "Viewing

Port Status and Configuring Port Parameters")

Check the Event Log to verify that the trunked ports are operating properly.

Enabling L4-based trunk load balancing

Enter the following command with the L4-based option to enable load balancing on Layer 4

information when it is present.

Syntax

trunk-load-balance [ L3-based | L4-based ]

When the L4-based option is configured, enables load balancing based on Layer 4 information

if it is present. If it is not present, Layer 3 information is used if present; if Layer 3 information is

not present, Layer 2 information is used. The configuration is executed in global configuration

context and applies to the entire switch.

Load balance on Layer 3 information if present, or Layer 2 information.L3-based

Load balance on Layer 4 port information if present, or Layer 3 if present, or Layer

L4-based

Default: L3-based load balancing
