[cisco-voip] Need help Verifying QoS configuration

[Ruttman, Peter G.]

Okay, I installed a new office and it has a separate building with a WAN
link to the larger office.  There is no PRI connection there so they
rely on the WAN to get to the larger office to get to the PRI to make
outbound and receive inbound calls.  I have enabled QoS but we are still
receiving reports of robotic or choppy voice.  I decided I wanted to
move up the chain created a verify policy to make sure that on each
router I was seeing marked packets.  Surprisingly, I have been unable to
do this.  I see with the command 'show policy-map int' that I am getting
packets marked with dscp of EF at the router but when I try to do this
on the switches I am unable to create a proper class/policy design to
see the packets.

I found a doc for the 3550 to do QoS at the wiring closet and modified
that with no luck.  Here's the design that isn't working:

class-map match-any VOICE
  match access-group 1
!
!
policy-map VERIFY
  class VOICE
    set ip dscp 40 (I ultimately want to use dscp 46 but I saw some
errors when I didn't have something defined in the class in the policy
so I put this here.  I've defined my router to watch for dscp 40 as well
so I should see the counters grow there as well if I get this working.)


access-list 1 permit 10.33.109.30


interface GigabitEthernet0/1
 switchport trunk encapsulation dot1q
 switchport mode trunk
 no ip address
 speed nonegotiate
 service-policy input VERIFY
 auto qos voip trust
 wrr-queue bandwidth 20 1 80 1
 wrr-queue queue-limit 80 1 20 1
 wrr-queue cos-map 1 0 1 2 4
 wrr-queue cos-map 3 3 6 7
 wrr-queue cos-map 4 5
 priority-queue out
!
!
interface GigabitEthernet0/2
 switchport trunk encapsulation dot1q
 switchport mode trunk
 no ip address
 service-policy input VERIFY
 auto qos voip trust
 wrr-queue bandwidth 20 1 80 1
 wrr-queue queue-limit 80 1 20 1
 wrr-queue cos-map 1 0 1 2 4
 wrr-queue cos-map 3 3 6 7
 wrr-queue cos-map 4 5
 priority-queue out
!
For the port with the phone that is listed in the access-list I have
tried the following:

interface FastEthernet0/11
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 9
 switchport mode trunk
 switchport voice vlan 109
 no ip address
 spanning-tree portfast

Or:

interface FastEthernet0/11
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 9
 switchport mode trunk
 switchport voice vlan 109
 no ip address
 mls qos trust device cisco-phone
 mls qos trust cos
 auto qos voip cisco-phone
 wrr-queue bandwidth 20 1 80 1
 wrr-queue min-reserve 1 5
 wrr-queue min-reserve 2 6
 wrr-queue min-reserve 3 7
 wrr-queue min-reserve 4 8
 wrr-queue cos-map 1 0 1 2 4
 wrr-queue cos-map 3 3 6 7
 wrr-queue cos-map 4 5
 priority-queue out
 spanning-tree portfast

Or:

interface FastEthernet0/11
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 9
 switchport mode trunk
 switchport voice vlan 109
 no ip address
 mls qos trust device cisco-phone
 mls qos trust dscp
 auto qos voip cisco-phone
 wrr-queue bandwidth 20 1 80 1
 wrr-queue min-reserve 1 5
 wrr-queue min-reserve 2 6
 wrr-queue min-reserve 3 7
 wrr-queue min-reserve 4 8
 wrr-queue cos-map 1 0 1 2 4
 wrr-queue cos-map 3 3 6 7
 wrr-queue cos-map 4 5
 priority-queue out
 spanning-tree portfast

Here is the output to show policy-map int:
