8.4.6 Handling of Traffic Classes
For the handling of traffic classes, the device provides:
X Strict Priority
Description of Strict Priority
With the Strict Priority setting, the device first transmits all data packets
that have a higher traffic class before transmitting a data packet with the
next highest traffic class. The device transmits a data packet with the
lowest traffic class only when there are no other data packets remaining
in the queue. In some cases, a high level of data traffic can prevent
packets with lower traffic classes from being sent.
In applications that are time- or latency-critical, such as VoIP or video, this
method ensures that high-priority data is sent immediately..
8.4.7 Setting prioritization
Assigning the Port Priority
Select the
QoS/Priority:Port Configuration dialog.
In the “Port Priority” column, you can specify the priority (0-7) with
which the device sends data packets which it receives without a
VLAN tag at this port.
Note: If you have set up VLANs, pay attention to the “Transparent
mode” (see Switching:VLAN:Global)
enable Switch to the Privileged EXEC mode.
configure Switch to the Configuration mode.
