Hello.
I've link between my 2 office - 100mb.
And i need config qos - for phone and buisness.
Provider can not help me - they also drop all marking traffic.
I want push 100 calls and all critical traffic when i have congestion.
But i have no idia - what i must do with traffic next. Any body can help me?
That is all i can do.
class-map ClassVoIP
match access-group name VoIP
class-map Critical
match access-group name Critical

policy-map QoSCriticalMap
class VoIP
class Critical
!
interface FastEthernet0/0
bandwidth 1024000
service-policy output QoSCriticalMap

ip access-list extended VoIP
permit udp 10.10.0.0 0.0.255.255 any
permit tcp 10.10.0.0 0.0.255.255 any
ip access-list extended Critical
permit tcp any any eq 21
permit udp any any eq 21

Hi Kuda,
You need you ISP to do QOS for End-to-End Qos to work,even if you apply QOS on traffic going out of your network ,the ISP will not treat it the way you want to.

"Provider can not help me - they also drop all marking traffic. "
You should clarify/verify this. Providers often will not honor QoS markings and they sometimes will reset markings, but they shouldn't be dropping packets/frames just because they are marked. You should also ask about L2 vs. L3 markings.
Assuming provider doesn't drop packets/frames, and assuming there's only your two sites in communication, you should be able to organize and queue traffic into at least 4 classes before forwarding traffic across link.
If the device is a 3750 (non Metro variant), your options are explained in the QoS section of the configuration guide. e.g. http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/12.2_50_se/configuration/guide/swqos.html. Take special note one of the four queues can be configured for priority (i.e. greate for VoIP bearer).
If the 3750 is a Metro variant, there are some additional QoS options. Again, configuration guide is a good place to start, e.g. http://www.cisco.com/en/US/docs/switches/metro/catalyst3750m/software/release/12.2_50_se/configuration/guide/swqos.html.

If QoS concepts are new to you, you might also want to examine various QoS design guides, e.g. http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND/QoSIntro.html and http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND/QoSDesign.html#wp999395.

ISP cannot give me QoS.
All i can do - it push traffic, in my order.
But question is - on router - a can use bandwith % - on 3750 - cannot.

"Normal" 3750s don't support router CBWFQ, but they do allow you to set ratios between 4 output queues. I.e. you can determine order of your traffic.
The references I provided in my first post provides details.
