Forming an ICX 7650 Stack

Be sure the rear module on all ICX 7650 units is cabled correctly before configuring stacking.

You can use the stack interactive-setup command as outlined in this procedure to configure an ICX 7650 stack. Other options for configuring a stack are also available. For more information on stack construction, refer to Traditional stack construction methods.

  1. (Optional) Use the show rear-module command to verify that the rear module is operating in a stacking mode. The default mode is 100-Gbps stacking. 
    ICX7650-48P Router# show rear-module
The rear module operates in stacking mode with 100G speed.
The rear module is configured in stacking mode with 100G speed.
    The example shows the unit is operating in default mode (100-Gbps stacking).
  2. If necessary, reconfigure the rear module for each unit in the stack to operate in the desired stacking mode. This may require removing the data uplink configuration. Refer to ICX 7650 rear-module options for more information.
  3. Enable stacking on each unit you plan to include in the stack. 
    ICX7650-48P Router# configure terminal
ICX7650-48P Router(config)# stack enable
Enable stacking. This unit actively participates in stacking
  4. Enter the stack interactive-setup command to configure the stack automatically. Respond to system prompts to confirm the stack configuration and to specify options such as the number of units in the stack, preferred unit IDs, the formation of multiple links as stacking trunks, and the creation of a ring topology. 
    ICX7650-48P Router(config)# exit
ICX7650-48P Router# stack interactive-setup
