Configuring the Working Mode of Leaf Switches

Configuring the Working Mode of Leaf Switches

Context

By default, if a leaf switch starts with no configuration, it performs a negotiation with the parent switch and attempts to join the SVF system in leaf mode, and you do not need to perform any configuration on the leaf switch.

If a switch starts with a configuration file, it enters the stack mode by default and cannot join the SVF system as a leaf switch. In this case, set the working mode of the switch to leaf mode using the BIOS menu or working mode menu during the startup process or using commands after the switch starts. The switch will then join the SVF as a leaf switch after each restart.

Procedure

  • An unconfigured switch is plug-and-play and does not require any manual configuration.

    By default, the working mode of a switch is auto-negotiation. That is, an unconfigured switch is plug-and-play and does not require any manual configuration.

    NOTE:

    If the negotiated working mode of a switch is leaf, the switch starts in leaf mode. To start the switch in other modes, manually configure the working mode of the switch.

  • If a switch starts with a configuration file, use either of the following methods to configure the leaf mode on the switch:

    • Method 1: Use commands to set the leaf mode after the switch starts.

      1. Run the system-view command to enter the system view.

      2. Run the stack command to enter the stack management view.

      3. Run the switch mode leaf member { member-id | all } command to set the working mode of the switch to leaf mode.

        By default, the working mode of a switch is auto-negotiation. That is, the working mode of a switch is determined through auto-negotiation.

        NOTE:

        The configured working mode takes effect after the switch restarts.

        This command can also be used on parent switches and takes effect only on the leaf switches that have joined an SVF system.

    • Method 2: Use the BIOS menu to set the leaf mode during the startup process.

      1. Log in to the switch through the console port.

      2. During the startup process, press Ctrl+B to enter the BIOS menu. The prompt information is "Press CTRL+B to enter BIOS menu".

      3. In the BIOS menu, choose 6. Modify stack parameters > 2. Modify stack configuration > 3. Leaf mode > 3. Return > 1. Continue to boot to set the working mode of the switch to leaf mode, and then choose to continue the startup process.

    • Method 3: Use the working mode menu to set the leaf mode during the startup process.

      1. Log in to the switch through the console port.

      2. During the startup process, press Ctrl+Y to enter the working mode menu. The prompt information is "Press CTRL+Y to modify the switch mode".

      3. In the working mode menu, choose 3. Leaf mode to set the working mode of the switch to leaf mode, and then the switch automatically restarts.

        The working mode menu is as follows:
        Press CTRL+Y to modify the switch mode ....................... 3
        
        If you modify the switch mode, the switch will reboot.
        
                   Switch Mode Menu
        
                1. Auto-negotiation mode       //Set the working mode to auto-negotiation.
                2. Stack mode                  //Set the working mode to stack.
                3. Leaf mode                   //Set the working mode to leaf.
                4. Continue to boot            //Continue to start.
        
        You have 30 seconds to select the menu, the system will continue to boot when time is up.
        Enter your choice(1-4):
