6.3 Priority
Setting
6.3.1 Priority Setting Page (Port Base)
There are Three (3) kinds of priority settings:
•
High/Low priority setting
•
IP Base (TOS) priority
•
VLAN tagging base (TCI) priority
Before you can do the priority setting, you have to check the
Enable priority
setting
box at
System Base Configuration
page.
Class of Service denotes the classification of traffic used to differentiate
services among traffic classes. The Switch offers 2-level priority (High and Low)
queues, which catch the priority information in the TOS field, port base, or
VLAN tag in the incoming frames as IEEE 802.1p/802.1q standard defines. In
this way, the switch controller guarantees the service for high priority frames to
some extent, depending on the load condition of incoming traffic. (At least, the
high priority service offers better than that of best effort service.) It also provides
different service ratio settings for users to shape the prioritized frames on the
streams in the incoming traffic.
6.3.2 High/Low priority setting
Specify high or low priority for each port. The port is in High priority if the port
has a check mark, otherwise, the port is in Low priority.
Each port has 2 priority queues for transmit. When both queues have data at
the same time, packet delivery will follow high/low ratio.
Default:
setting all port in
Low priority
