Cisco Router IOS degrade

[gkurunthasalam]

Hi,

I am trying to degrade a IOS version from 3800 Software (C3825-IPBASE-M), Version 15.0(1)M2 to (C3825-ADVIPSERVICESK9-M), Version 12.4(25f) in a Cisco 3825 router. while I am trying to transfer IOS image from laptop to cisco router using TFTPd32 software, I am receiving following error. %Error opening tftp://192.168.1.1/c3825-advipservicesk9-mz.124-25f.bin (Timed out). I have  changed the LAN cable connected between router and laptop and still getting this error.

1. Please advise whether this degrade of IOS is possible?

2. Please advise how to rectify this error and upgrade IOS 12.4

Thanks

Gokul

Error given is almost like that router cant find the source file in your TFTP server.Also can you ping your laptop from the router?

Yeah, I could able to reach from laptop to router and vice versa. I have installed TFTPd32 software.

Ok, then  make another attempt to download and you should see hits in the log viewer  tab of TFTpd32.

If you cant see any hits in the logs check whether you have BIND your tftp service with your correct IP.

Log viewer tab would say what the cause of the error if you get a hit and still cant download (Edit : didn't notice the above reply from Justin)

Please check if the following are configured correctly:

• Current Directory (should be the folder where the IOS image is stored)
• Server Interfaces (192.168.1.1 in your case)
• Settings > TFTP > Advanced TFTP Options > Bind TFTP to this address ( 192.168.1.1 in your case)
