diffserv domain default

Hello everyone,

This post is about the diffserv domain default command.

I am not able to understand the purpose of this diffserv domain command.

I tried testing it by changing all the values in eNSP via the 'trust upstream default' command, while also using another new domain "trust upstream A".

I could see the edited output in 'display diffserv domain default' and 'display diffserv domain a', but I could not see any changes on the packet traversing the interface on which it is configured. 

So by doing this lab, I have come to the conclusion that either I do not understand how to use this diffserv command, or eNSP does not reflect its principle correctly.

That is all I want to share with you!
