Which version and feature set are you trying to use and how much flash is installed/available?<br />

<div>
The IOS upgrade gets to 99 percent and stops. <br />
<br />
&nbsp;How are you verifying that the upgrade is completed till 99%. Do you mean the image download to the router is completed 99%?<br />
<br />
&nbsp;Are you trying TFTP or FTP to copy the image?<br />
<br />
TFTP will support just 16MB, if the file size is more then you need to use FTP to download the image.<br />
<br />
Also can you paste the output of which commands you are executing?

Solarwinds supports files larger than 32MB.<br />

<div>
You are right. SolarWinds supports files larger than 32 MB. <br />
<br />
But as mentioned in my earlier comment, Cisco IOS will not support more than 16 MB. So even if we use SolariWinds as TFTP server and Cisco IOS as TFTP client, it won't work. <br />
<br />
We need both the TFTP server and the TFTP client (Cisco IOS) to support files more than 32 MB.<br />

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.

Routers

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.
