How many levels of priority are possible when using Class of Service CoS marking on frames?
How many levels of priority are possible when using class of service (CoS) marking on frames? A Layer 2 frame contains a 3-bit PRI (Priority) field that identifies the class of cervice (CoS) markings. These markings allow a frame to be marked with 8 levels of priority (level 0 – 7).Click to see full answer….

Also asked, what happens when an edge router using IntServ QoS determines that the data pathway Cannot support the level of QOS requested?Data is forwarded along the pathway using DiffServ. Data is not forwarded along the pathway. Data is forwarded along the pathway using IntServ but not provided preferential treatment.One may also ask, what is the functionality provided by the Class of Service CoS parameter? Class of Service (CoS) is a way of managing traffic in a network by grouping similar types of traffic (for example, e-mail, streaming video, voice, large document file transfer) together and treating each type as a class with its own level of service priority. Also to know, what happens when the memory queue of a device fills up and new network traffic is received? The network device drops all traffic in the queue. The network device will drop the arriving packets. The network device will drop the arriving packets.What is CoS in QoS?QoS is an umbrella term which covers the use of features such as policing, shaping, traffic classification, and advanced queuing mechanisms. CoS is a form of QoS limited to layer-2 Ethernet and it uses 3-bits (8 values) of the 802.1Q tag to differentiate your traffic. Therefore no trunking, no CoS.
