NoteNew switches are primary-capable by default.
Because stacks can consist of switches of different series and different models, ExtremeXOS does not restrict configuration settings based on the capabilities of any particular node in the stack. Therefore, you are responsible for ensuring that your configuration settings are appropriate for all switches in the stack.
The following switch families come from the factory with stacking-support enabled with stack ports set to a default configuration. The following table describes the default configuration for each switch:
|Switch||Stack port default configuration|
|ExtremeSwitching 5320||SummitStack V400|
|ExtremeSwitching 5420||SummitStack V40|
|ExtremeSwitching 5520||SummitStack V160|
|ExtremeSwitching 5720||SummitStack V40|
ImportantExtremeSwitching 5720 and ExtremeSwitching 5520 switches contain different types of EXOS images. The ExtremeSwitching 5720 requires an onie_x86_64 image type, and the ExtremeSwitching 5520 requires a summit_arm image type. Before building a mixed stack of these two switch families, all switches must have the same release level image loaded onto all nodes.
Once a mixed stack of ExtremeSwitching 5720 and ExtremeSwitching 5520 switch families has been built, a software upgrade is required. Download and install the onie-summitarm-bundle.lst image, which combines the onie_x86_64 image and the summit_arm image into one bundle.
Alternatively, you can use the following two step upgrade process:
Instructions for physically setting up the stack are provided in the hardware installation guide for your switch.
NoteIf the stack will use MPLS, only the 5520 switch can act as primary and backup.

X440G2-24t-10G4.4 # enable stacking You have not yet configured all required stacking parameters. Would you like to perform an easy setup for stacking operation? (y/N)
Executing "configure stacking easy-setup" command... For every node in the 4-node stack, this command will: - enable stacking - configure a stack MAC address - choose and configure a slot number (this node will be assigned to slot 1) - configure redundancy to minimal (slot 1 will be the master node) - configure the stacking protocol to enhanced Upon completion, the stack will automatically be rebooted into the new configuration. Warning: If stacking is already configured, this command will alter that configuration. Do you wish to proceed? (y/N)
Enter y again to confirm. All of the switches reboot automatically and form a stack in which one switch is the primary, one is the backup, and the rest are standby nodes. Easy Setup configures all other required stacking parameters for every switch in the stack.
