TNR vs TNS

[kk1313]

I'm updating the firmware on several different model of ICX switches that I have, but I'm running into a bit of confusion. For the ICX7650-48p, the recommended firmware is the 08.0.95g ufi version, but the zip file contains both a TNR08095gufi.bin and a TNS08095gufi.bin file. I can't find anything in the release notes that specifies a difference between these two versions. Is there a difference? What situations would call for either version being applied over the other?

TNS denotes switching (layer 2 only) image while TNR denotes routing (layer2+layer3) image. You can check 'show version' to see what you are running now. Hope that helps!

Hi @kk1313 

Basically the TNS the third letter means Switching code the TNR means routing code 

Switching guide :

Routing guide :

As we can see, the routing code allows us some features like create VEs/ip routes/ Routing protocols etc...

To check what code you are actually running we can check with a 'show version'

This is a ICX-7150 so the terminology is SP and not TN like your case that is ICX-7650

ICX7150-C12 Switch#show ver

As we can see in the example that switch is running SP 'S' that means that is running switching code.

Another example : 

ICX7250-24P Router#show ver

In this case we have SP 'R' that means that is running routing code 

I hope it helps
