Hi all,
I am a junior network engineer.
I am currently working on catalyst 3650 and wondering if my understanding is correct about qos.
1) a dscp or cos value in incoming packet gets translated to internal dscp value.
2)internal dscp value gets translated to cos value.
3) packets get assinged to a certain queue based on cos value.(by looking at cos-queue map)
I have a couple of questions here.
Q1) why internal dscp value gets translated to cos value to assign to a queue. It seems like a waste.
Q2) When a port is configured as an access port or
trunk port, can I put “qos trust dscp”?
I mean, can non routed port looks at dscp value?
Thanks in advance,
Summers
