Hi there !
I'm trying to configure LAN QoS in a 3560G, but it seems that the config is now working.. (probably I'm doing something wrong...)
I tryied to make it as clean as possible
--- CONFIG ---
mls qos
mls qos map cos-dscp 0 8 16 26 34 46 48 56
class-map match-all CIPC
match access-group name CIPC
policy-map CIPC
class CIPC
set dscp ef
interface GigabitEthernet0/1
service-policy input CIPC
ip access-list extended CIPC
permit udp any any range 16384 32767
permit tcp any any range 2000 2002
permit icmp any any
--- show policy-map ---
#show policy-map interface gi 0/1
GigabitEthernet0/1
Service-policy input: CIPC
Class-map: CIPC (match-all)
0 packets, 0 bytes
offered rate 0 bps, drop rate 0 bps
Match: access-group name CIPC
Class-map: class-default (match-any)
0 packets, 0 bytes
offered rate 0 bps, drop rate 0 bps
Match: any
0 packets, 0 bytes
rate 0 bps

As you can see there are 0 packages in Class-map CIPC..
I'm trying to set all voice traffic and call signalling as EF.
Can you help me ?
Andrei.

The counters don't work. This is a know and well documented limitation with the majority of Catalyst IOS switches. You need at least a Catalyst 4500 SupIV with NetFlow hardware for the counters to work. There are some other statistics available though:
show mls qos interface X/X statistics
show platform port-asic stats enqueue FastEthernet X/X
show platform port-asic stats drop FastEthernet X/X
The statistics on the older Catalyst 3550 were much better in my opinion as these would show you packet counts for classified, policed and dropped packets per interface. The 3560/3750 (& 2960) only have counters for 'in profile' & 'out of profile' when a policer is attached, however these don't distinguish between marked down or dropped, nor do they tell you what DSCP value they were.
