Setting Policy: Example 4

This example demonstrates use of the Quality of Service (QoS) policy commands. QoS policies are configured to achieve the following:

• Give priority to a particular user group (for example, Management user group). You can give specific traffic a higher priority by setting or increasing the 802.1p priority and changing the DSCP value.

• Prioritize the traffic stream accessing a particular server, for example, set the 802.1p.

• Change the packet priority and DSCP value based on the current DSCP value.

Configuring a QoS Policy for Incoming Traffic:

Step 1: Create QoS policy 401 to apply to incoming traffic on an interface:

1 Create a QoS policy that has an index number of 401:

W310-1(super)# ip qos-list 401

W310-1(super/QoS 401)#

Step 2. Create composite operation 12 to set the CoS and DSCP values of packets:

1 Create a composite-operation that has an index number of 12:

W310-1(super/QoS 401)# composite-operation 12

2 Configure composite operation 12 to assign packets a CoS value of 7 and a DSCP value of 45.

W310-1(super/QoS 401/CompOp 12)# cos 7

W310-1(super/QoS 401/CompOp 12)# dscp 45

3 Exit Composite Operation mode:

W310-1(super/QoS 401/CompOp 12)#

exit

W310-1(super/QoS 401) #

Step 3. Add rule 105 to QoS policy 401. This rule will apply composite operation 14 to traffic from the user group mgmt:

1 Add a rule 105 to QoS policy 401:

W310-1(super/QoS 401)# ip-rule 105

2 Configure rule 105 to filter packets that are coming from the members of the mgmt user group:

W310-1(super/QoS 401/ip rule 105)# source-user-group

mgmt

3 Apply composite operation 12 to the rule

W310-1(super/QoS 401/ip rule 105)# composite-operation

Op12

4 Exit IP rule mode for rule 105:

W310-1(super/QoS 401/ip rule 105)# exit

W310-1(super/QoS 401)#

Step 4. Add rule 107 to QoS policy 401. This rule will assign a CoS priority of 7 to traffic going to the server at 192.168.0.15:

1 Add a rule 107 to QoS policy 401:

W310-1(super/QoS 401)# ip-rule 107

2 Configure rule 107 to filter packets that are destined to 192.168.0.15:

W310-1(super/QoS 401/ip rule 107)# destination-ip host

192.168.0.15

3 Configure rule 107 to apply a CoS priority to traffic destined to the server at

192.168.0.15. This operation sets the 802.1p priority to 7.

W310-1(super/QoS 401/ip rule 107)# composite-operation

CoS7

4 Exit IP rule mode for rule 107:

W310-1(super/QoS 401/ip rule 107)# exit

W310-1(super/QoS 401)#

Step 5: Create composite operation 13 to change the CoS priority and DSCP value of packets:

1 Create a composite-operation to change the CoS and DSCP values.

W310-1(super/QoS 401)# composite-operation 13

2 Configure composite operation 13 to set the 802.1p priority to 6.

W310-1(super/QoS 401/CompOp 13)# cos 6

3 Configure composite operation 13 to set the DSCP value to 60.

W310-1(super/QoS 401/CompOp 13)# dscp 60

Note: The show composite-operation 13 command shows the configured operation.
