ASR 9K IOX XR Turboboot

[netops044]

Hi Experts,

Im trying to downgrade XR image in ASR9K from 4.3.1 to 4.2.3. The VM file size is about 330Mb. TFTP operation is getting terminated  after some point of time. Im using 3Cdeamon server and has configured  max timeout and retries already. Is there anything Im missing here.

I have tried changing MGMT_INTF, CHECKSUM=0, BLKSIZE=1400 etc.

TFTP gets terminated after copying about 150Mb. Total VM size is 330Mb

Appreciate your quick response.

Hi all,

I was able to complete the tftp operation using Solar Winds. I have completed the downgrade successfully.

Thanks,

If you have RSP440, next time use USB directly connected in the RSP, it will be faster and easier than TFTP.
