G8332 Command Reference for ENOS 8.4
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.
This feature provides the G8332 the capability to filter IP packets based on the
802.1p bits in the packetʹs 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.
