We are all aware of the traditional way of transferring IOS files from and to Cisco Catalyst Switches, Cisco Routers and Cisco PIX/ASA firewall devices using TFPT, FTP and lately https. However there is also one more way to copy the IOS files, which is known as Secure Copy (SCP). The Secure Copy (SCP) is a secure and authenticated method of copying a configuration file or transferring an Image files to Cisco Catalyst Switches, Cisco Routers and Cisco PIX/ASA firewall devices.


Cisco Systems introduced the Secure Copy (SCP) feature in the following IOS releases





This feature was introduced.


This feature was integrated into Cisco IOS 12.0(21)S.


This feature was integrated into Cisco IOS 12.2(25)S.

PIX/ASA firewalls 7.1 and above, FWSM 3.1 and above.


The Secure Copy (SCP) works on SSH protocol on port 22 which is like an encrypted tunnel. This tool is very useful especially to transfer files for upgrades or to perform safe backups.
