9105axw-b EWC Conversion

PatrickMorgan — Mon, 05 Jul 2021 19:58:40 GMT

TL/DR:
9105axw-b

Problem 1 – How do I make space?

Problem 2 – Am I copying the file correctly?

I received a Catalyst 9105axw-b intending to use the 9800 Embedded Wireless Controller. After reading several documents and watching the 9100 series videos, I was confident that I could convert the device. Most of the documentation is aimed towards the other 9100 series devices and have directions with unacceptable commands, like config t.

I am having a difficult time getting the access point to allow me to tftp the IOS bin file. Below is part of the show version output:

I have attempted several methods. copy source dest doesn’t work in this IOS.-

ap-type mobility-express tftp://192.168.1.245/9105/ap1g8 tftp://192.168.1.245/9105/C9800-AP-iosxe-wlc.bin

This outputs a long string of blank lines with sporadic hyphen characters followed by invalid input detected.

ap-type mobility-express tftp://192.168.1.245/9105/C9800-AP-iosxe-wlc.bin
Output:

Output:

curl: (23) Error
transfer command failed (Error 23)
Image transfer failed
Attempted u-boot xmodem with baud of 38400 ---- took too long

I am making an assumption that the device is running out of space. I cannot seem to find the commands to delete, as it is handcuffed to what can be deleted and I am having trouble viewing the files. Clearly my /tmp is 100% full (fixes with reload). But I would like to have enough space to download and use the image.

Any assistance would be welcome.

- Take a look at this thread , which is similar , I also advice to use FTP for the transfer :

I had attempted to use FTP as well and receive the following:

ap-type mobility ftp://cisco:cisco@192.168.1.115/9105/C9800-AP-iosxe-wlc.bin

Output:

Error: ftp to be implemented in image_download.sh.

I attempted to follow some of the advice in the article

Still not accepting it.

- Wouldn't you need this command instead (?) :

ap-type EWC-AP tftp://192.168.1.245/9105/C9800-AP-iosxe-wlc.bin

This is not an acceptable command for the loaded IOS. The command tree has only has 3 sub commands for ap-type. Guides for other 9100 series say to use mobility-express for certain IOSes. This command tree has only has 3 sub commands for ap-type.

-capwap

-cloud

-mobility-express

I think your particular ap-model does not support EWC :
