Hello, 
 
I have tried in the past to save a Field Upgrade Software (FUS) to disk0 on a Cisco 6500 using a Sup 720 and configuring is as a TFTP Server using disk0 and the file name (Example Listed below). But when I SSH into the WLC and tried to copy the FUS from the Router over to the WLC I would receive the following error, 
 
Router 
tftp-server disk0:AIR-CT5500-K9-1-7-0-0-FUS.aes 
 
WLC 
Mode............................................. TFTP &nbsp; 
Data Type........................................ Code &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
TFTP Server IP................................... X.X.X.X 
TFTP Packet Timeout.............................. 6 
TFTP Max Retries................................. 10 
TFTP Path........................................ / 
TFTP Filename.................................... CT5500-K9-1-7-0-0-FUS.aes 
 
This may take some time. 
Are you sure you want to start? (y/N) y 
 
TFTP Code transfer starting.

Copy Field Upgrade Software (FUS) from a Cisco Router to WLC

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.

Wireless Networking

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
