TitleHow to create a stack with Summit switches
Objective
How to create a stack with Summit Switches.
Environment
  • Summit
  • EXOS
Procedure

Before connecting the stacking cables to add the switch to stack verify the following is the same:
 

  • License Level-----------"show licenses"(all master capable nodes should have the same license)
  • EXOS Version----------"show version images" (Ensure that every switch (or node) in the stack is running the same version of ExtremeXOS.)
  • Active Partition---------"show switch" (Primary or Secondary whatever is booted that should be same for all devices in stack)


Enabling stacking will remove the configuration. You will have to migrate the configuration manually.

To configure a new stack:

1.  Physically connect the nodes using the stacking ports.

2.  Power on the nodes.

3.
For each switch on which the stacking ports are not already enabled, issue the command enable stacking-support.

4. Make sure all switches have the same stacking protocol and stacking-support configured

configure stacking protocol [enhanced | standard]
configure stacking-support stack-port [stack-ports | all] selection [native {V80 | V160} | V320} | alternate]


5.  Login to any of the nodes through the console port, preferably the one you want to use as the master. If you plan to use Easy Setup, log into the intended master node.
If the stack is a new stack, the default parameters are in effect.

6.  Type "show stacking" to verify the stack.
The show stacking command displays all nodes in the stack. All nodes are in a disabled state and all nodes appear as master nodes.

7.  Type "enable stacking" from the master.
Note:
All switches must have stacking-support enabled, but stacking disabled, before you run Easy Setup.

8.  This command presents you the option of using the Easy Setup procedure. Type "configure stacking easy-setup"

9.  Restart the stack and type "reboot stack-topology"
The configuration is set to default values while entering the stacking mode, so all previously entered configuration information (except for the NVRAM-based stacking parameters, selected image, and failsafe account information) is not available.

10.  Login to the intended master node and verify the stack type "show stacking", "show slot", and "show stacking configuration" commands.

11.  If the stack configuration is successful:

  • All nodes are visible in the stack.
  • All nodes move to the active state.
  • Some time after the nodes become active, each node is present in the configured slot.
  • After the roles are finalized, you can see one master node, one backup.


12.  Verify that the master node is the one you intended to be the master.

Additional notes
For troubleshooting a stack see this article:
Getting started with Summit Stacking

Having trouble with a Summit x460-G2 see article below:
X460-G2-10G4 will not allow native stacking to be enabled

Note: The below tool will make things faster but make sure it caught everything and let us know if the tool doesn't convert all ports.
