I have qos in 4 router cisco connected by metroethernet, and i have one firewall connected in the same metroethernet.
The config in router cisco is:
set cos 5
set cos 3
shape average 6000000
I can implementate QOS in firewall fortigate, and work without problem, or i need install another router beteween router and firewall, and connected the router direct to metroethernet with qos. What you recommend?.
