Hi
I am tryng to configure QoS on 3 switches (2960, 3560 and 3750) with this configuration:
mls qos
!
!
class-map match-all QOS_DATA_CLASS
match access-group name QOS-DATA
class-map match-all QOS_DEFAULT_CLASS
match access-group name QOS-DEFAULT
class-map match-all QOS_VOICE_CLASS
match access-group name QOS-VOICE
class-map match-all QOS_SIGNALING_CLASS
match access-group name QOS-SIGNALING
!
policy-map QOS-SOFTPHONE-POLICY
class QOS_DEFAULT_CLASS
set dscp default
class QOS_SIGNALING_CLASS
set dscp cs2
class QOS_DATA_CLASS
set dscp cs1
class QOS_VOICE_CLASS
set dscp cs3
!
!
interface GigabitEthernet0/34
no switchport
ip address 10.10.11.1 255.255.255.252
ip ospf network point-to-point
priority-queue out
service-policy input QOS-SOFTPHONE-POLICY
!
!
interface GigabitEthernet0/47
switchport access vlan 150
spanning-tree portfast
service-policy input QOS-SOFTPHONE-POLICY
!
ip access-list extended QOS-DATA
permit tcp any any eq 22
permit tcp any any eq 465
permit tcp any any eq 143
permit tcp any any eq 993
permit tcp any any eq 995
permit tcp any any eq 1914
permit tcp any any eq ftp
permit tcp any any eq ftp-data
permit tcp any any eq smtp
permit tcp any any eq pop3
ip access-list extended QOS-DEFAULT
permit ip any any
ip access-list extended QOS-SIGNALING
permit tcp any any range 2000 2002
permit tcp any any range 5060 5061
permit udp any any range 5060 5061
ip access-list extended QOS-VOICE
permit udp any any range 16384 32767
!
but when I check the show commands I see that QoS is not working.
CoreA#sh policy-map interface g0/34
GigabitEthernet0/34
Service-policy input: QOS-SOFTPHONE-POLICY
Class-map: QOS_DEFAULT_CLASS (match-all)

Match: access-group name QOS-VOICE
Class-map: class-default (match-any)
0 packets, 0 bytes

Match: any
What do I do bad?
The flow is the next:
Computer with CIPC --------> Switch 2960 or 3560 or 3750 ------------------> switch core ---------------> CIPC
I have wireshark in a port mirror on switch 2960, 3560 and 3750. In wireshark I always see the packets marked with default label.
I hope you can help me.
Regards.

Please, see this post: https://supportforums.cisco.com/discussion/11079636/c2960s-qos
The show policy-map interface doesn't work on these switches.

Hi Daniele
Thanks for your help, I understand that but why when I use Wireshark in a span port on switches all packets are marked with default label?
Regards.

Try this config:
policy-map QOS-SOFTPHONE-POLICY
class QOS_VOICE_CLASS
set dscp cs3
class QOS_SIGNALING_CLASS
set dscp cs2
class QOS_DATA_CLASS
set dscp cs1
class class-default
set dscp default
