說明

 This article discusses how to set up Port Based VoIP QoS on Dell Networking Switches running OS9.

 The Following platforms do not support this command as it was deprecated in earlier versions of OS9.
1. Z9100
2. S6100
3. S5048

 

QoS Configuration Port Based VOIP Example

 

Here the VoIP phone sends traffic with Differentiated Services Code Point (DSCP) value 46.  The Dell Networking OS9 switch will be configured to trust the ingress traffic DSCP value and set priority to the hardware queue servicing this traffic.
 
Follow these steps:
 
1.  Configure an input policy map to trust ingressed DSCP values.
2.  Attach the input policy map to and interface.
3.  Configure the hardware queue mapped to DSCP value 46 to use strict priority.

  • By default, the map is set to a DSCP value of 46 mapped to a hardware queue of 2.
     
Command Parameters
Force10# conf Enter configuration mode.
Force10(conf)# policy-map-input my-trust-dscp Create an input policy map.  This line is using "my-trust-dscp" as the example name.
Force10(conf-policy-map-in)# trust diffserv Trust DSCP values.
Force10(conf-policy-map-in)# interface te 0/0 Enter interface configuration mode.  You can use a range command here.
Force10(conf-if-te-0/0)# service-policy input my-trust-dscp
Force10(conf-if-te-0/0)# exit		 Attach the policy map to the interface as an input policy.
Force10(conf)# strict-priority unicast 2 Specify a hardware queue to use strict priority scheduling.
 
Dell Networking OS9 devices use the following default mappings for DSCP values to particular hardware queues:

 
DSCP Value S,C,Z-series Queue E-series Queue
0-15 0 0-1
16-31 1 2-3
32-47 2 4-5
48-63 3 6-7
