Selecting Native and Alternate Stacking Ports

• To select between the native and alternate stacking ports, use the following command for each switch in the stack:
  configure stacking-support stack-port [stack-ports | all] selection [native {V80 | V160 |V320 | V400} | alternate]

  

  Note

  Not all options are available for all switches. Refer to Stacking Considerations for Each Switch Model for details.
• To display the stacking and stacking-support configuration, use the following commands:

  show stacking-support

  show stacking stack-ports

  show stacking {node-address node_address | slot slot_number} detail

• To unconfigure the stacking-support feature, use the following command:
  unconfigure stacking-support
  

  Note

  Commands that contain the stacking-support keyword apply to the local switch only. This means that each switch that will use alternate stacking ports must be configured separately. When the stack is fully active, you can use the telnet slot slot-number command to log in to another node over the stack to unconfigure SummitStack-V on that node only. There is no way to intentionally or accidentally unconfigure the stacking-support options on all nodes in a stack.
• When the stacking-support feature has been configured as required on all nodes in a stack, reboot each node.
• Run the show stacking stack-ports command to verify that the stack has been properly connected.
