VOIP QOS Mitel Phones

Post by furiousfifou »

I need to set QoS for VoIP over OmniSwitch 6250 and 6450.

The network is star and 6450 is the core network

The Autocom and phones are on VLAN 15
Each switch port where a phone is connected is set like this because there's a computer plugged it on the phone:
eg port 1/1 :

-> default vlan 3 Port 1/1 (VLAN 3 = data)
-> vlan 15 1/1 802.1q (VLAN 15 = voip)

I know that with Alcatel phones by enabling:
-> qos priority 5 phones
This is to enable the Sufis qos for voip

I saw on another post (viewtopic.php?t=16548) that adding mac addresses of phones from other manufacturers to the group "alaPhones" normally auto qos for voip should work.
Suppose then that the phones is like mac address of addresses starting with 11: 22: 33: xx: xx: xx, is it correct if I did:
-> mac policy group "alaPhones" 11: 22: 33 :00: 00: 00 mask ff: ff: ff: 00: 00: 00
-> qos priority 5 phones
-> qos apply

Or is it better to do the QOS for vlan in this way:
->policy condition c.voice.vlan15 source vlan 15
->policy action a.stamp.p5.dscp46 802.1p 5 dscp 46
->policy rule r.voice.p5.dscp46 precedence 100 condition c.voice.vlan15 action a.stamp.p5.dscp46 log
->qos apply

In either case, how can I check that voip is priority over data ?

Should you configure the qos only on the network core or also on other switches ?
thank you beforehand
Best regards

ps : excuse my english, i'm french :?

Hi,
I prefer second way with policies.
you can check with
> show active policy rules
also there are some other ways for port-mirroring (with wireshark), port monitoring or QoS logs...

You should configure QoS at all your switches.

As I understand it, both solutions are good

I half up the qos today. For now I used the first method.

I await the return of users. If the first method was not conclusive, I would use the second method.

Best regards
