Hi!
I am trying to automate the process of upgrading IOS on Cisco devices.
Everything seems to be working fine until the process of copying the file
begins.
The issue I am encountering is that ansible keeps sending data (I assume it
keeps sending the same file a couple of times in a stream) to the IOS
device.
I noticed this issue when I logged in to one of the switches to which I am
trying to upgrade and saw how the file keeps growing and growing, to up to
four times its size (i.e. filesize is ~ 21k but it was growing already on
th 80k+).
Process ends when the "timeout" time is reached. Subsequently, the file
gets deleted from the switch, as the switches interprets that the file
transfer was interrupted.
Here is y core. Any help will be much appreciated:
