+      - Specifies the source file. The path to the source file can either be
+        the full path on the network device or a relative path as per path
+        supported by destination network device.

+      - Specifies the destination file. The path to the destination file can
+        either be the full path on the Ansible control host or a relative
+        path from the playbook or role root directory.
+    default:
+      - Same filename as specified in src. The path will be playbook root
+        or role root directory if playbook is part of a role.
+
+requirements:

+
+notes:
+   - Some devices need specific configurations to be enabled before scp can work
+     These configuration should be pre-configued before using this module
+     e.g ios - C(ip scp server enable)
+   - User privileage to do scp on network device should be pre-configured
+     e.g. ios - need user privileage 15 by default for allowing scp
+   - Default destination of source file
