Config Backup - "show run" error on IOS-XR Devices?!
« on: July 24, 2018, 01:04:45 PM »
Dear NeDi Community,

I've got a problem on backing the config of some devices (maybe IOS-XR devices only). SSH-Account is working correct. But one device throws an "EVNT:" and in the verbose output I can see, that the "show run" output stays in "WAIT:" Mode, while on the working device the output shows the prefix "CONF:" beginning with the line with "version xx.x" in it.

Both Backups were done over the WebGui and executed the following command:

Code: [Select]
/var/nedi/nedi.pl -v -B0 -SAFGgsjmvpadobewitu -a <Device-IP>
Here the excerpt of the "Not working IOS-XR device" output

Code: [Select]
Config (CLI)   ----------------------------------------------------------------

And here the excerpt of the Output from the working IOS device:

Do you have some hints what to do or where to look to get it working?!

Thanks

Search for IOS-xr in inc/libcli.pm

Replace the line:
$cmd{'IOS-xr'}{'cfst'} = '^!! IOS XR Configuration';

With this:
$cmd{'IOS-xr'}{'cfst'} = 'version';

Not sure if all IOS-xr use that format now, but if they do I can adjust it for the next release...
