ISR 4221 can't enter global configuration mode

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.

Re: ISR 4221 can't enter global configuration mode

Hello,

 

What are your options at the prompt ?

 

4KISR#?

Re: ISR 4221 can't enter global configuration mode

I can do any of the show commands with no problem. I was even able to do the factory reset command. However, when the router booted, it still had the same problem. 

I read over the document you attached and I don't believe it is diagnostics mode. If it was, the prompt should look like this router(diag)# but I have the standard prompt of router#.

I appreciate your suggestions because I am pretty much out of ideas myself.

Re: ISR 4221 can't enter global configuration mode

Hello,

 

really weird, especially since these are new routers. What is in flash (dir flash:) ?

Re: ISR 4221 can't enter global configuration mode

The contents of flash are really weird as well. This is the display of the sho flash command.

Normally this would just be the image file. Not sure why it is as large as this.

Re: ISR 4221 can't enter global configuration mode

Hello,

 

can you try (if you haven't already) to load an image onto a USB stick and boot from that USB ?

Beginner

Re: ISR 4221 can't enter global configuration mode

I booted the router into ROM monitor mode and entered the command to boot from usbflash0: and received a device not found error message. This is the same error message I get when I try and boot to an image saved to flash. I also tried issuing a dir ? command at the rommon prompt and it returns a failed to read directory contents, file not found.

Re: ISR 4221 can't enter global configuration mode

I opened a TAC for this.  Seems to be image related.  Image loaded is for SD-WAN deployments, which apparently locks the global configuration mode.

 

I downloaded the recommended IOS-XR image and booted from usb0: via rommon.  Problem resolved.

This is a very interesting issue. And your identification of the issue and the solution certainly merits +5.

 

Thank you for posting this.

Re: ISR 4221 can't enter global configuration mode

Hi, hello! Which IOS XR image file did work for you?

I'm having the same issue, please advice.

 

Thanks.

Re: ISR 4221 can't enter global configuration mode

Hi,

 

I used Everest 16.6.5.  Although Fuji 16.9.4 is the current suggested release.

 

 

 

Re: ISR 4221 can't enter global configuration mode

reload the router, keep hitting enter once it prompts up.  when everything is scrolling, just type in en, conf t and do what you need to do; you only get one shot!

If you make any mistakes,. you will have to start the process all over again.

Re: ISR 4221 can't enter global configuration mode

Currently the router booted with SDWAN image, Need to upgrade the router to IOS-XE.

 

New os change Steps :

 

Step 1 : First download the new ios in belwo link

step  2: Copy to usb device 

step 3 : Insert the usb to Router


Step 4 :  go to Rommon Mode .
