How to copy file from FTP server to XR-OS ASR9010

[news2010a]

Hello folks, I have been reading the filesystem docs on XR-OS but I couldn't find this task:

From a given FTP server inside my company network, I need to download a number of files (PIE and SMU bundle) to start an upgrade (ISSU) in the ASR9K test box.

Can you please clarify the syntax and how I can mput file from the FTP server?
Doing 'ftp' the command prompt in my ASR9K is not being recognized and sorry I am in a hurry and I can't locate the command in the documentation.

Thank you,

Marlon

Sorry, I see now:

ftp: —Copies from an FTP network server. The syntax is ftp:[[[//username [:password]@] location]/directory]/filename.
