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.

Note on On switches covered in this guide, “mixing” ToS DSCP policies and 802.1p

Combining

priorities is not recommended. Refer to the Note on page 6-10.

Policy Types

For more on DSCP, refer to “Terminology” on page 6-6.

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.
