Steps
Summarized steps:
• Configure 'stack enable' on the intended active controller unit at configuration level.
• Enter 'stack secure setup' on the intended active controller unit at device level.
Detailed Steps
1. Connect the units in a stack based on the connection guidelines. Select a unit that you want to
become an active controller. Configure 'stack enable' at configuration level as seen in the following
log.
ICX7250-24P Switch(config)#stack enable
Enable stacking. This unit actively participates in stacking
stacking is enable. optical monitoring for stacking ports 1/2/1, 1/2/3 is not
available.
ICX7250-24P Switch(config)#
2. Once stack enable configured, this command will configure two default stack ports 1/2/1 and 1/2/3 as
seen in the message displayed. This can be confirmed using 'show run' command. If you want to
connect stack units using the retimer ports (1/2/5 to 1/2/8), 'default-ports' command can be used to
change the default ports manually on the devices.
ICX7250-24P Switch(config)#stack unit 1
ICX7250-24P Switch(config-unit-1)#default-ports 1/2/5 1/2/7
3. Verify with show running-config that the default ports are set to 1/2/5 and 1/2/7.
ICX7250-24P Switch(config-unit-1)#show run
Current configuration:

ver 08.0.30T211

stack unit 1
module 1 icx7250-24p-poe-port-management-module
module 2 icx7250-sfp-plus-8port-80g-module
default-ports 1/2/5 1/2/7
4. Enter 'stack secure setup 'at device level. As shown in the following example, this command triggers
a Brocade 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. This process will assign IDs to the units.
5. During stack formation you will be prompted to use the RING topology. If 'n' is selected, it prompts
you to enter the desired number of units either upstream or downstream depending on the
connections.
NOTE
During the secure-setup process, after one minute of inactivity, authentication for stack members
expires, forcing you to restart the process.
To exit the secure-setup, enter ^C at any time.
