2.8 QoS Setting
In some ports that need to have a high priority to manage the data transfer,
QoS
should be changed. Set the port’s QoS to high to determine the port will
always transfer their
data first.
2.8.1 Priority Mode
Before users do the priority setting, you have to check the “
Enable High Priority
”
box at Class of Service page. 24-port Modular Smart Switch offers 2-level priority (High and
Low) queues, which catch the priority information in the
Port-Based
,
IP/DS based
, or
VLAN
based
in the incoming frames as
standard IEEE 802.1Q 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.
2.8.2 Class of Service Configuration
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.
Default:
All ports in LOW priority.
IP/DS base (TOS) priority recognition:
Ports with TOS enabled will induce
switch to
inspect the specific field of IP packet to control packets priority. Making a check mark in front of
port ID indicates this port is TOS priority recognition enabled.
