6. QoS Quality of Service is a mechanism that is used to prioritize certain traffic as it is forward through the switch Traffic can be classified as High or Normal priority and when the switch is heavily loaded it is the Normal priority packets that are dropped first You can select how traffic is prioritized by using one of the three QoS modes which are selected using the QoS Mode drop down list Note Only one QoS mode can be active at one time It is not possible for example to prioritize traffic using the DSCP value and 802 1p tag QoS Disabled QoS is turned off and all packets have equal priority 802 1p Packets are prioritzed using the content of the VLAN tag The 802 1p field is held within the VLAN tag of a packet The field is three bits long so can hold eight values 0 7 inclusive When QoS Mode is set to 802 1p the 802 1p Configuration table appears which allows a priority normal or high to be set for each of the eight values You can use the Prioritize Traffic drop down list to quickly set the values in the 802 1p Configuration table Select All Normal Priority to set all values to normal priority or select All High Priority to set all values to high priority Use Custom if you want to set each value individually Note Because end stations like PCs are not usually VLAN awate they do not create VLAN tagged frames As a result this method of prioritization is not ideal when there are a lot of PCs connected to th
