Transferring IOS XE Image to multiple Access Switches

[Tes3awy]

To begin with, thanks a lot for this handy program. It's really helpful and saves a lot of time.

I just had one issue. I am trying to transfer cat9k_lite_iosxe.17.03.03.SPA.bin (about 480MBs) to three C9200L-48P-4G access switches, but I got an error socket.timeout(). However, I was able to find the IOS image on the three switches flash and the images were verified!

I added socket_timeout=200.0 to this line before running to prevent any timeouts but I still get one!

Any reason for why this is happening?

Thanks a lot!

Hi,

Thanks a lot for your comment.

It's difficult to see what is the issue here.
For debugging purposes, you may add a "catch-all" at line 73 to catch any exception and see more details.

Something like:
except:
print(“Error: ”, sys.exc_info()[0], “occurred.”)

I hope it helps.
Best,
Jerome

Hello @jerome-t,

Today, I tried doing it again but raised the socket timeout to 250.0 and it worked for 6 access switches concurrently. It's all about the timeout. So for a ~500MBs IOS image size, socket_timeout=250.0 is perfect.

Update:

The IOS image transfer took exactly 00:14:28 to be transfered to all six switches on 1G link.
