First Issue
Using napalm-ios/napalm-base develop branch as of 2017-04-29 and netmiko 1.3.0 (and sometimes develop version on this same date).
Running on a CSR1000V using
If I use
configure replaceoperation and the file contains the following:Then the SCP transfer would fail.
It would fail to transfer the file. Debugging on router side indicated the SCP communication started, but ended when I would expect the file to be transferred.
Increasing the SCP timeout from 5 seconds to 30 seconds did not help. It doesn't look like the transfer even starts.
Manual transfer of same file from server to router works using SCP:
Second Issue
Same router would not let me to a configure replace where I removed the self-signed certificate. In other words, I had a perfectly valid config file that removed the self-signed certificate. I would get a message complaining about 'no quit' (i.e. the end of the self-signed certificate). I had to manually remove it and then do the configure replace operation.
Third Issue
The self-signed certificate contains a tab in the quit line and must be structured exactly this way. You cannot just copy and paste it (as the tab will get converted to spaces).
