Spectrum NCM Capture Fails using SSH/SCP

Issue/Introduction

I am attempting a capture of a "Cisco IOS - SSH Capable" device. The main communication mode is specified as SSH/SCP. 

When I run the capture I get the error "SPC-OCC-10747: Error capturing configuration for host: SCP disabled on device". 

Why do I get the error "SPC-OCC-10747: Error capturing configuration for host: SCP disabled on device". 

Cause

The device should use SSH/ SCP to communicate with Spectrum but SCP is disabled on the device, so is not able.

Resolution

This is a device problem - please ask the device owner to enable SCP on the device, to allow NCM to communicate with it.

Additional Information

We can test the SCP functionality of the device directly and outside of Spectrum.  

You can test manually against the router which has SSHv2 and SCP configured by executing the following command on SpectroSERVER machine bash shell. This is similar to what NCM does.
 
Example command: scp <user>@<device_IP>:running-config .

For example: scp [email protected]:running-config .

 
Note: The dot/period character at the end of the command line is required.
 
The command will prompt you to enter the user’s password. It will get the configuration from the router provided the user has been configured with privilege 15 and SSHv2 and SCP has been configured properly.

If running manually works, then NCM should work too. If not, then it is a network or router’s configuration issue.
