Hi,

Do any of you know what the '6144K/2048K bytes of memory' or '8192K/2048K bytes of memory' stands for?
The output below is from 2 c2500, but I haven't been able to figure out how much memory they really have.
I need to upgrade the IOS and reckon that more memory is needed, but I want to make sure exactly how much.
According to Kingston these routers come with 2MB of 'non-removable' memory. But if you check out Cisco's product reference, you find out that they come with 4MB!!!
So I'm not sure whether the '/2048K' refer to that 2MB of nrm, or if, for instance the '6144K/2048K' mean: you have a 6MB module with 2MB of non-removable mem (you have a 4MB module).

=(

Help appreciated.

Cheers, Gabriel.

Use the "show flash" command to verify that you have enough memory on your system for the IOS software that you want to load. Flash memory is erasble reprogramable ROM that holds the operating system image and microcode. multiple versions can be sometimes be held here. RAM/DRAM stores routing tables, the ARP cash, and some other stuff, the current running configuration is also stored here. The backup/startup config file is stored in NVRAM (nonvolotile. ROM cointains contains diagnostics, bootstrap, and OS software
To replace the IOS first you should back-up a copy of the current IOS,just in case the new one doesn't work, use the copy flash tftp command for this. Of course you will need a computer to act as a TFTP server, after you use the command the router will ask for the IP address for the TFTP server then you are ready to copy your new IOS to your router. have your new image at the TFTP server and the name of it, the router will ask you for it then it will verify there is enough space and ask if want to erase the current one, if there is not enough space then erase the current image. After the image is loaded then use the show flash command again to check the size of the new image, make sure this the same size as the one in the TFTP server(make sure all of the image is there).
Then use the "boot system" command to specify the system iomage to use at startup.
Then use the "reload" to reload the router and you new image should be in there.
Let me know if it works

You add the 2 together to get the total DRAM you have in your router.
