Cisco Advanced security IOS will not load on a 2810 router using TFTP
Posted on 2009-02-24
I was attempting to update the standard ISO to c2800nm-advsecurityk9-mz.124-20.YA.bin on a 2810 router using TFTP. I verified connection from the host machine to the router and verified that we had enough RAM and Flash. Using the copy tftp flash command everything looks and runs well, until about 46 to 50% the command line prompt changes from !!!!!!!! to 00000000000 on a consistent basis. If I watch the TFTP services window on my local machine it will continue to load the ISO file past the 100% mark. I tried this a few times and on another computer and a different router with the same results. At that point I even tried a lower version of the advance security IOS.
We were able to send back the original standard ISO via TFTP to get the routers working. I have not seen this before especially the 0000000000 instead of the !!!!!!! on the router during installation. Any ideas.
