Table 1-2 Configuration items of global parameters Item Private Net IP Description Configure a private IP address pool for the stack. The master device of a stack must be configured with a private IP address pool to ensure that it can automatically allocate an available IP address to a slave device when the device joints the stack. Mask Build Stack When you configure a private IP address pool for a stack, the number of IP addresses in the address pool needs to be equal to or greater than the number of devices to be added to the stack. Otherwise, some devices may not be able to join the stack automatically for lack of private IP addresses. Enable the device to establish a stack. After you enable the device to establish a stack, the device becomes the master device of the stack and automatically adds the devices connected to its stack ports to the stack. You can delete a stack only on the master device of the stack. The Global Settings area on a slave device is grayed out. Return to Stack configuration task list.
