I have a nortel IPT system and am in the process of setting up QOS. So my network topology is like this:
I have 3 floors of a building:
Floor 28 - 4 - 3650s and a 4507R
Floor 29 - 4 - 3650's
Floor 30 - 4 -3650's
Each individual 3650 has a fiber home run back to the 4507R.
Now the Nortel Signaling Server and the IP card in the switch are plugged into the 4507R. All the phones are plugged into the 3560's.
I found an article from Nortel on how to set up QOS for the 3560's but nothing for the 3650 and it really doesn't do much in the way of telling how to test. So here is a sample of the config i've put on my 3650 switch:
class-map match-any voice
match access-group 150
class-map match-any signaling
match access-group 151
policy-map qos
class voice
trust dscp
class signaling
trust dscp
interface FastEthernet0/41
switchport trunk encapsulation dot1q
switchport mode trunk
service-policy input qos
access-list 150 permit ip any any dscp ef
access-list 151 permit ip any any dscp cs5
So port 41 above is the port the phone at my desk pluggs into. Does this provide everything I need for qos on my layer 2 lan? Do i need to put any policy on the ports that the Nortel signaling server and IP card are plugged into on the 4507R? How about the trunk ports that are the home runs from the 3560's to the 4507R, anything to be added there? Below is the article that I found for the 3560 running 12.1. My 3650's are running 12.4 so things are a bit different.
1. interface range {port-range separated by commas}
2. flowcontrol receive off
3. flowcontrol send off
4. exit
5. mls qos
6. end
7. show mls qos
8. copy running-config startup-config
9. mls qos trust dscp
10. access-list 100 permit ip any any dscp ef
11. access-list 101 permit ip any any dscp cs5
12. class-map voice
13. match access-group 100
14. class-map signaling
15. match access-group 101
16. policy-map qos
17. class voice
18. trust dscp
19. class class-default
20. {Optional} police {rate-bps} burst-size} [exceed-action {drop | policed-dscp-transmit}]
21. exit
22. exit
23. interface {interface-id}
24. service-policy input qos
