Hi,

Are they all running the same version of IOS? Which version are they running?

<div>
Yes, they are all running &quot;Cisco IOS Software, 1841 Software (C1841-IPBASE-M), Version 12.4(3i), RELEASE SO&quot; 
</div>


Yes, they are all running "Cisco IOS Software, 1841 Software (C1841-IPBASE-M), Version 12.4(3i), RELEASE SO"

<div>
It sounds like an IOS bug. I'll have a look on Cisco bug toolkit to see if there are any hits for this problem.

We have three Cisco 1841 routers with a QOS policy setup on each. We then have the policy applied to MFR0 and write it to memory. The QOS then works great for a period of time and then the applied policy just disappears from interface MFR0. We have three routers all with the same config and they all do the same thing. I then have to go back in and reapply the policy to MFR0. The policy itself doesn't get deleted, just the line in MFR0 (as pictured). I was told it was an issue with our version, 12.4? Has anyone else experienced this issue or fixed is successfully?<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.
