I just purchased four brand new ISR4221 routers as part of an Academy lab set up. I can get them to boot fine, can enter user exec mode and privileged exec mode. However, when I try and enter global configuration mode, I get a command not supported error message. I also get that message if I issue a copy run start or erase startup config command. I am stuck at this point. I have worked with Cisco routers for 20 years and have never had any of them act this way. I have searched the blogs and the internet and cannot find a solution. Any ideas would be greatly appreciated.
