Quality of Service (QoS): Managing Bandwidth More Effectively
Using QoS Classifiers To Configure QoS for Outbound Traffic
Figure 6-10. Example of Configuring and Listing 802.1p Priority Assignments for
Packets Carrying Specific IP Addresses
Assigning a DSCP Policy Based on IP Address
This option assigns a previously configured DSCP policy (codepoint and
802.1p priority) to outbound IP packets having the specified IP address (either
source or destination). That is, the switch:
1. Selects an incoming IPv4 packet on the basis of the source or destination
IP address it carries.
2. Overwrites the packet’s DSCP with the DSCP configured in the switch for
such packets, and assigns the 802.1p priority configured in the switch for
the new DSCP. (Refer to “Differentiated Services Codepoint (DSCP)
Mapping” on page 6-58.)
3. Forwards the packet through the appropriate outbound port queue.
N o t e o n On switches covered in this guide, “mixing” ToS DSCP policies and 802.1p
C o m b i n i n g priorities is not recommended. Refer to the Note on page 6-10.

Steps for Creating a Policy Based on IP Address. This procedure
creates a DSCP policy for IPv4 packets carrying the selected IP address
(source or destination).
1. Identify the IP address you want to use as a classifier for assigning a DSCP
policy.
