Va7206VXR Upgrade IOS

[nfordhk]

  Hi,

We need to upgrade our IOS on our Va7206 for to support VRF. I was looking at the new IOS in downloads and they all mention NPE-G2 however, we are using NPE-G1 does anyone know if these IOS are backwards compatible or if someone can recommend an version?

We are currently using

Version 12.4(12)

Hi

You can choose 15.x IOS.  Whenver you choose a 15.x version it prompts you for either "Software on Chassis" or NPE-G2. So please select "Software on Chassis" option for the NPE-G1.

Hi Nicholas,

The below link takes you to the software download page:

http://www.cisco.com/cisco/software/navigator.html?mdfid=268437992&flowid=820

There you can notice two separate links:

1.Software on chassis - this is for NPE-G1 and below

2.Cisco 7200 Series NPE-G2 Network Processing Engine - this is for NPE-G2

The NPE-G2 IOS is not backward compatible. It will not run on the NPE-G1

The way you differentiate between an NPE-G1 and a NPE-G2 image is by the letter "p" in the image name.

The image which contains "p" is for NPE-G2.

For example,

c7200p-adventerprisek9-mz.152-4.S1.bin is an NPE-G2 image

whereas

c7200-adventerprisek9-mz.152-4.S1.bin is compatible with NPE-G1 and other NPEs.
