Can I use Remote Copy Protocol (RCP) to transfer images to devices?
A. Use the RCP transport protocol for image transfers only on Cisco IOS devices that support the CISCO-FLASH-MIB. Catalyst switches that run Supervisor software older than 5.2, and 700 Series devices do not support the RCP protocol. The Cisco IOS devices can not use RCP if they only support OLD-CISCO-FLASH-MIB, (for example, MC3810) or if they do not support any Flash Management Information Base (MIB) (for example, RSP 7000 devices running Cisco IOS Software Releases 10.3-11.0).
