Brocade FastIron Ethernet Switch Stacking Configuration Guide - Manual (Page 133)

Specifying the port modules identifies the device to the active controller. Use the show running-
config command to get port module information. You only need to specify one port module,
because the active controller generates information for other modules.
3. 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 equal to or smaller than the active controller priority.
4. Specify the trunks or ports on this backbone device that connect to a peripheral unit in a substack.
Brocade(config-unit-1)# peri-trunk 2/3/1 to 2/3/2
Brocade(config-unit-1)# peri-trunk 2/3/7 to 2/3/8
Automatically configuring peripheral devices in a mixed stack
Perform the following steps to configure the peripheral devices in a mixed stack using the automatic
configuration method.
1. From the ICX 6610 device that is the active controller, configure the stack unit ID.
Brocade(config)# stack unit 3
2. Specify a port module.
Brocade(config-unit-3)# module 1 icx6450-24-port-management-module
Specifying the port modules identifies the device to the active controller. Use the show running-
config command to get port module information. You only need to specify one port module,
because the active controller generates information for other modules.
3. (Optional) Create stacking trunks on this peripheral device.
Brocade(config-unit-3)# stack-trunk 3/2/1 to 3/2/2
Brocade(config-unit-3)# stack-trunk 3/2/3 to 3/2/4
4. (Optional) Specify the devices that this peripheral device connects to.
Brocade(config-unit-3)# connect 1/3/1
Brocade(config-unit-3)# connect 4/2/3
The connect command cannot override the physical connections, but it is used on peripheral
devices to match a unit ID to a peripheral device in the case of a unit replacement or stack
construction.
5. Repeat Step 1 through Step 4 for each additional peripheral device. Specify a different stack unit ID
for each device in Step 1.
6. Enable stacking.
Brocade(config-unit-8)# stack enable
Configuring a mixed stack using manual configuration
A mixed stack can be configured manually to allow more individual control over configuration
parameters than using automatic configuration of the mixed stack.
You must configure each device that you want to include in the stack from the device itself; you cannot
configure all devices from the active controller as you can in the automatic configuration method.
Perform the following steps on the backbone device designated as the active controller.
