Quality of Service Configuration
Quality of Service (QoS) commands configure the 802.1p priority value and DiffServ Code Point
value of incoming packets. This allows you to differentiate between various types of traffic, and
provide different priority levels.
802.1p Configuration
This feature provides the G8124 the capability to filter IP packets based on the 802.1p bits in the
packet's VLAN header. The 802.1p bits specify the priority that you should give to the packets
while forwarding them. The packets with a higher (non-zero) priority bits are given forwarding
preference over packets with numerically lower priority bits value.
