3.2.6. QoS
This switch provides quality of service (QoS) to prioritize the packet forwarding
when traffic congestion happens. This switch supports port-based (4-level
output queue) and 802.1p (8-level priority to 4-level queue mapping)QoS
functions. Strict and weight round robin (WRR) QoS mode are supported.
3.2.6.1. QoS Configuration
This page is mainly to set the QoS mode (First Come First Service, All High
before Low, and WRR) and 8-level priority to 4 –level queue mapping.
First Come First Service: The sequence of packets sent is depending on
arrive orders. This mode can be regarded as QoS is disabled.
All High before Low: The high priority packets sent before low priority
packets.
WRR: Weighted Round Robin. Select the preference given to packets in the
switch's high-priority queue. These options represent the number of higher
priority packets sent before one lower priority packet is sent. For example, 8
Highest 4 second-high means that the switch sends 8 highest-priority packets
before sending 4 second-high priority packets.
QoS Priority: 8-level (0~7) priority can be mapped to 4-level (Highest,
Second-High, Second-Low, Lowest) queue.
3.2.6.2. Per Port Configuration
Per-port priority can be configured and shown in this page.
Port Number: the ports in the switch.
Port Priority: port priority can be disable or 0-7.
