This option will provide better service of selected network traffic over various
technologies.
802.1p
Select this option to Activate/Deactivated the 802.1p IEEE 802.1p establishes eight
levels of priority (0 ~ 7). Although network managers must determine actual
mappings, IEEE has made broad recommendations. Seven is the highest priority
which is usually assigned to network-critical traffic such as Routing Information
Protocol (RIP) and Open Shortest Path First (OSPF) table updates. Five and six are
often for delay-sensitive applications such as interactive video and voice. Data
classes four through one range from controlled-load applications such as streaming
multimedia and business-critical traffic - carrying SAP data, for instance - down to
"loss eligible" traffic. Zero is used as a best-effort default priority, invoked
automatically when no other value has been set.
IP QoS
Select this option to Activated/Deactivated the IP QoS on different types (IP ToS and
DiffServ). IP QoS function is intended to deliver guaranteed as well as differentiated
Internet services by giving network resource and usage control to the Network
operator.
Applications QoS
Select this option to Activated/Deactivated the different application packets prioritized
on the queues.
VLAN Group QOS
Select this option to Activated/Deactivated the 4094 VID on the 4 different queues.
VID (VLAN ID) is the identification of the VLAN, which is basically used by the
standard 802.1Q. It has 12 bits and allow the identification of 4096 (2^12) VLANs. Of
the 4096 possible VIDs, a VID of 0 is used to identify priority frames and value 4095
(FFF) is reserved, so the maximum possible VLAN configurations are 4,094.
