Configuring the Type of Leaf Switch Ports to Be Connected to the Parent Switch

Configuring the Type of Leaf Switch Ports to Be Connected to the Parent Switch

Context

By default, leaf switches connect to a parent switch using some default ports. You can also configure the leaf switch ports to be connected to a parent switch according to networking requirements. Subsequently, leaf switches can use only the configured ports to connect to a parent switch.

To learn about the default and configured leaf switch ports to be connected to a parent switch, see Table 2-5.

Notes

  • N*10GE/N*40GE refers to the last N 10GE/40GE interfaces on the device.
  • When auto-negotiated or configured N*10GE or N*40GE ports are connected to a parent switch, these ports cannot be used as common service ports. For example, when any one of ports from 40GE1/0/1 to 40GE1/0/4 on a CE6810-48S4Q-EI is connected to a parent switch, the remaining ports cannot be used as common service ports.

  • In V100R005C00 and later versions, the auto-negotiation function takes effect on a CE6810-48S4Q-EI switch only one time. Leaf switches can use only the ports negotiated for the first time to connect to a parent switch. To change the leaf switch ports, you must manually configure the type of leaf switch ports.

Procedure

  • Method 1: Use commands to set the type of leaf switch ports to be connected to the parent switch 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 leaf uplink-port type { auto-negotiation | 4*10ge | 8*10ge | 2*40ge | 4*40ge | 6*40ge } member { member-id | all } command to set the type of leaf switch ports to be connected to the parent switch.

      By default, leaf switches connect to a parent switch using ports listed in Table 2-5.

      NOTE:

      After you configure the type of leaf switch ports to be connected to a parent switch, restart the switch for the configuration to take effect.

      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 type of leaf switch ports to be connected to the parent switch 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 or CTRL+E to boot DFX".
    3. In the BIOS menu, choose 6. Modify stack parameters > 2. Modify stack configuration > 1. Auto negotiation mode/3. Leaf mode > 1. Auto negotiation mode/2. 4*10GE/3. 8*10GE/4. 4*40GE > 3. Return > 1. Continue to boot to set the type of leaf switch ports to be connected to the parent switch, and then choose to continue the startup process.

      This step uses a CE6810-48S4Q-EI as an example and may vary according to device models.

  • Method 3: Use the working mode menu to set the working 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 4. Continue to boot > 1. Auto negotiation mode/2. 4*10GE/3. 8*10GE/4. 4*40GE to set the type of leaf switch ports to be connected to the parent switch.

      This step uses a CE6810-48S4Q-EI as an example and may vary according to device models.

      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 the device.
      
      You have 30 seconds to select the menu, the system will continue to boot when time is up.
      Enter your choice(1-4):4
      
      Modify the uplink port type if needed.
      
                 Uplink Port Menu
      
              1. Auto-negotiation mode       //Configure the uplink port to work in auto-negotiation mode.
              2. 4*10GE                      //Configure the last four 10GE ports as uplink ports.
              3. 8*10GE                      //Configure the last eight 10GE ports as uplink ports.
              4. 4*40GE                      //Configure the last four 40GE ports as uplink ports.
              5. Continue to boot            //Continue to start the device.
      Enter your choice(1-5):
