Hello Sycor
I have been unable to find any definitive information about this particular error in specific Cisco documentation. However, my understanding is that the tclsh command is only available in non-controller devices. Controller devices are the vManage, vBond, and the vSmart devices. The “controller mode” here I assume referrs to the fact that the device detects that it is in one of these three other modes, which don’t support the TCL shell. Make sure that the rest of your configurations are set up as in the lesson to ensure that the device is not running as a vBond or vSmart controller. Take a look and let us know how you get along. If this doesn’t resolve it let us know so we can help you further…
I hope this has been helpful!
