Brocade FastIron Ethernet Switch Stacking Configuration Guide - Manual (Page 135)

1. Specify the stack unit ID.
Brocade# stack unit 1
Because you are configuring each device from the device itself, and the stack is not yet formed, the
stack unit ID is 1 for each device.
2. Specify the trunks or ports on this backbone device that connect to a peripheral device in a
substack.
Brocade(config-unit-1)# peri-port 2/3/1
Brocade(config-unit-1)# peri-port 2/3/2
Brocade(config-unit-1)# peri-port 2/3/7
Brocade(config-unit-1)# peri-port 2/3/8
Brocade(config-unit-1)# exit
3. Specify the stack unit ID that you want this device to have in the stack.
Brocade(config)# stack suggested-id 2
The system attempts to assign a device bootup ID as its stack unit ID. However, due to timing
issues or the possible unavailability of the bootup ID, a peripheral device might not get the stack
unit ID that you want. The optional stack suggested-id command allows you to specify the stack
unit ID devices other than the active controller.
4. Enable stacking.
Brocade(config)# stack enable
Manually configuring peripheral devices in a mixed stack
Perform the following steps to configure the peripheral devices in a mixed stack using the manual
configuration method.
1. Specify the stack unit ID that you want this device to have in the stack.
Brocade(config)# stack suggested-id 3
The system attempts to assign a device bootup ID as its stack unit ID. However, due to timing
issues or the possible unavailability of the bootup ID, a peripheral device might not get the stack
unit ID that you want. The optional stack suggested-id command allows you to specify the stack
unit ID devices other than the active controller.
2. Enable stacking.
Brocade(config)# stack enable
3. Repeat Step 1 and Step 2 for each additional peripheral device. Specify a different suggested stack
unit ID for each device in Step 1.
Basic mixed stacking configuration examples
Configuration example for mixed stacking using automatic
configuration
Configuration and verification examples for an automatic configuration of mixed stacking.
1. Use the show running-config command to view the mixed stack configuration.
Brocade# show running-config
2. Use the show stack command to verify the mixed stack configuration.
Brocade# show stack
