2821 IOS Upgrade Path

[kellyrudnick]

Where can I find information regarding the details and upgrade path for the 2821 Intergrated services router. We are looking to upgrade from 12.4 (

c2800nmc-spservicesk9-mz.12.4xxx.bin) to 15.1. Is their a spefici location to look for in the download or IOS area for upgrade paths?

Thanks.

Hi Kelly,

You should check the Software Download centre :

http://www.cisco.com/cisco/software/release.html?mdfid=279120798&flowid=7533&softwareid=280805680&release=15.1.4M1&relind=AVAILABLE&rellifecycle=ED&reltype=latest

The above link gives you the memory requirements for the 15.1(4)M1 image for the C2821 router.

For your specific feature set, here is the information you need:

c2800nmc-spservicesk9-mz.151-4.M1.bin

Release Date: 22/JUN/2011

Size: 54760.05 KB (56074284 bytes)

Minimum Memory: DRAM:512MB   Flash:128MB

Hope this helps,

cheers,

soraya

Hi Soraya,

Do you need to buy or install license for upgrading IOS to 15.1?

Thanks.

Do you need to buy or install license for upgrading IOS to 15.1?

If you are using the same Feature set (example:  IP Base) then you don't need to do so.  If you are going from IP Base to IP Services, for example, then yes.
