Avaya Phones, Cisco Switches and QoS (MPLS network in between)

Question:

I am implementing QoS on Cisco 3560X Price our MPLS network. Our environment exists of a mix of Cisco 2960 and 3560 switches. The IPT system is Avaya CM with Avaya phones.
The WAN network is a MPLS network.

Ports are configured for access and voice vlan (no trunking), one vlan for voice, one for data (vlan 1 is disabled).
I dont have Qos coonfigured on LAN just wanted to configure on WAN Router where my Mpls link is connected.I have 45 Mb Mpls links on all sites connected to each other.

I have multiple sites connected via MPLS and i have control at both sides.Current config is mentioned below in which DSCP marking is not done for signaling. Can anyone tell me the best config with example.

Current Config on all Cisco Router where MPLS link is terminated at all sites.

class-map match-any business
match access-group name business_critical
class-map match-any non-business
match access-group name non-critical
class-map match-any premium
match access-group name interactive_video_or_voice
policy-map parent-test
class premium
  set ip dscp ef
  priority percent 20
class business
  set ip dscp default
  bandwidth remaining percent 60
class non-business
  bandwidth remaining percent 30
class class-default
policy-map MPLS-OUT
class class-default
  shape average 46080000
  service-policy parent-test

interface GigabitEthernet0/0
service-policy output MPLS-OUT
ip access-list extended interactive_video_or_voice
permit ip 10.x.x.128 0.0.0.63 any-----Voice Device Vlan
permit ip host 10.x.x.11 any---New_VC_VLAN


Answer:


This is the same type of config that I use on mine. The only question that I have is your business class. Are you wanting to set your dscp to default for a reason? I'm assuming that you're going into an mpls cloud from your provider? If so, do you pay for qos support where they will match on a marking and then give that priority through Cisco 3560V2  their lsp?
