Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure Quality of Service for Outbound Traffic
3. Assign the DSCP policies to the selected VIDs and display the result.
Figure 15-25. The Completed VID-DSCP Priority Configuration
The switch will now apply the DSCP policies in figure 15-25 to packets
received on the switch with the specified VLAN-IDs. This means the switch
will:
Overwrite the original DSCPs in the selected packets with the new DSCPs
specified in the above policies.
Assign the 802.1p priorities in the above policies to the appropriate
packets.
QoS Source-Port Priority
QoS Classifier Precedence: 6
The QoS source-port option enables you to use a packet’s source-port on the
switch as a QoS classifier. Where a particular source-port classifier has the
highest precedence in the switch for traffic entering through that port, then
traffic received from the port is marked with the source-port classifier’s
configured priority level. Different source-port classifiers can have different
priority levels.
