Configuring a mixed stack using automatic configuration
Defines how to configure a mixed stack with an automatic configuration device.
You must configure all the devices in a mixed stack on the ICX 6610 device that you intend to be the
active controller.
In automatic configuration, configuration for all stack members is done on the stack member that you
intend to be the active controller. It should have the highest priority of all stack units.
Perform the following steps to configure the active controller in a mixed stack using the automatic
configuration method:
1. From the device that you want to be the active controller, configure the stack unit ID.
Brocade(config)# stack unit 1
2. If there are two backbone devices, specify the priority.
Brocade(config-unit-1)# priority 128
Priority is used in the case of a switchover between the active and standby controllers. The priority
should be the same on each controller.
3. Specify the trunks or ports on this backbone device that connect to a peripheral unit in a substack.
Brocade(config-unit-1)# peri-trunk 1/3/1 to 1/3/2
Brocade(config-unit-1)# peri-trunk 1/3/7 to 1/3/8
4. If there are two backbone devices, perform the steps in the “Mixed stack automatic configuration for
a backbone standby controller device” task.
5. To configure peripheral devices, perform the steps in the “Mixed stack automatic configuration for
peripheral devices” task.
