Using secure-setup to configure a traditional stack in a ring topology

The following figure shows three ICX 7750 stacking units connected in a ring. The secure-setup example that follows is for 12 ICX 7750 units in a ring topology. However, the procedure can be used for any stackable ICX device and any size traditional stack.

Figure 4  Traditional stack with ring topology
  1. Connect the devices using the stacking ports and stack cabling. For more information, refer to the appropriate hardware installation guides.
  2. Power on the units.
  3. Connect your console to the intended active controller. The unit through which you run secure-setup becomes the active controller by default.
  4. Issue the stack enable command on the intended active controller. 
    device# configure terminal
device(config)# stack enable
device(config)# exit
  5. Enter the stack secure-setup command. As shown in the following example, this command triggers a Ruckus proprietary discovery protocol that begins the discovery process in both upstream and downstream directions. The discovery process produces a list of upstream and downstream devices that are available to join the stack. Secure-setup can detect up to 11 units in each direction (22 units total); however, you must select a total number of units that is less than the maximum stack size for the device because the controller is also part of the stack.
    NOTE
    During the secure-setup process, after one minute of inactivity, authentication for stack members expires, forcing you to restart the process.
    NOTE
    To exit the secure-setup, enter ^C at any time.
    The following example shows the suggested discovered topology.

  7. If the Brocade device supports stacking trunks, the system next displays available trunk options in turn and requests your input on how many ports to include. The range is presented in parentheses, and the current setting is presented in square brackets. For example, (1-3) [ 1 ] indicates that the current connection is a single-port link, and you have the option of electing a 2-port or a 3-port trunk instead. When prompted, enter the desired trunk size as shown in the following example.

Do you accept the unit id's (y/n)?: y
  8. Review the topology and the unit IDs that are displayed. When prompted, enter y if you want to accept the assigned unit IDs.
    NOTE
    You can also enter n to decline the assigned unit IDs. The system then prompts you to enter different IDs, warns that changing the unit IDs manually may modify stack configuration, and recommends that you save the configuration and reload it after the stack is ready.
  9. The active controller automatically checks all prospective stack members to see if they are password-protected. If a unit is password- protected, enter the password before you to add the unit. If you do not know the password, take one of the following actions:
    • Discontinue secure-setup by entering ^C.
    • Obtain the device password from the administrator.
    • Skip this unit and continue the secure-setup for your stack. The password-protected device and all devices connected behind it will not be included in the setup process.

    In the following example, the second unit is password-protected, so you are asked for the password.

    For ICX devices, an equal sign (=) is used to indicate connections between trunk ports as shown in the previous example.

    NOTE
    In the previous example, D indicates a dynamic configuration. After you perform a write memory, the D changes to an S, for static configuration.

  13. Once all of the stack units are active, enter the write memory command on the active controller. This command initiates configuration synchronization, which copies the configuration file of the active controller to the rest of the stack units.
    NOTE
    The secure-setup process may modify your configuration with information about new units, stacking ports, and so on. For this reason, it is very important to save this information by issuing the write memory command. If you do not do this, you may lose your configuration information the next time the stack reboots.

    The secure-setup process for your stack is now complete.
