This message occurs because one or both stacking ports are configured to use the alternate port on this switch (instead of the native stacking port) but the hardware to provide the port is not present. The message occurs on X450a or X450e series switches when the option card that provides the port(s) is not present.
Use the "show stacking-support" command to view the configured stacking port selection. There are two methods to prevent this message from being displayed in the future: (1) Power down the unit. Insert an appropriate option card such as an XGM2-2xf card into the option slot. Power on the unit and use the option card. (2) Use the "configure stacking-support stack-ports <stack-ports> selection native" command to use the native stacking port(s) on the switch. Then reboot the switch for the configuration to take effect.
Warning
Alternate stacking port is selected on %switchStr% %slotNumStr% but the option card slot is empty.
