ISR4K with IOS-XE 3.16.6s: ping with option dscp

HuGGy

Level 1

For an ISR 4431 chassis with an IOS-XE 3.16.6S, I noticed that there was a new option "dscp" on the command "ping X.X.X.X source Gi0 / 0/0 dscp af31".

What is the difference between the "dscp" option and the "tos" option?

Is the "dscp" option functional?

From my notes :

 

Here's the mapping you will need. "=" means something like "maps to" or "is equivelent to".

 ef = dscp 46 = 101110 = tos 0xb8 (184) = ip prec 5

af31 = dscp 26 = 011010 = tos 0x68 (104) = ip prec 3

af32 = dscp 28 = 011100 = tos 0x70 (112) = ip prec 3

cs3 = dscp 24 = 011000 = tos 0x60 (96) = ip prec 3

 

You'll want to use the decimal tos values (in parenthesis) for your e-pings.

 

Difference from my point of view is, when you want to capture packet you do not see DSCP, then you need to map to ToS.

Thank you for this return but that is not my question.

I know the command "ping" with the extended option "TOS" but it appeared to the command "ping", an option "DSCP" in the latest versions IOS-XE and I wonder that it is the contribution of this new option compared to the option "TOS"
