Mitel MiVoice Business/MCD/3300 / Re: Mass Configuration Edit

« on: February 28, 2013, 02:21:51 PM »

 Good news part is that is exactly what I am trying to do, as we have two sites, and I am trying to do one of two things. Implement proper QOS and save my colleagues the trouble of reconfiguring the phones each times someone moves two and from our two sites.

I have CDP all setup and working, and I am trying to slowly plug away at the list of static phones. Hahaha but yeah, which puts me exactly in the bad news part of the scope.

Thanks though.

Mitel MiVoice Business/MCD/3300 / Mass Configuration Edit

« on: February 28, 2013, 01:03:30 PM »

Hey Guys,

Currently I have 200+ phones that have a hard coded vlan ID and a priority tag. I want to change those options and am wondering if there is a quicker way to do so that to go to each phone and change the hard coded settings.

Is there a configuration file I can edit that the phones pull from the TFTP server?

Not sure if this is possible, but if it is, it would be really appreciated. If not possible, I will have to bear the consequences of hard coding.

Thanks,

Steve

Louzada,

Thanks for the reply. I am currently working on getting this setup and will go from there. Will eventually post a config as well w/ specifics. I do have a question, did you do any class matching and policy set w/ policers?

Or did you strictly focus on the expedite queue

Any suggestions?

To get started:

On my 2960 access layer switches the config that I will have would be as follows:

interface giga x/0/x
switchport mode access
switchport access vlan X1
switchport voice vlan x2
spanning-tree portfaast
mls qos trust cos
mls qos trust dscp

---------------


Now I understand that mitel uses CDP and recognizes the phones, so I should have no problem by using voice vlan statement. Now that I have all my interfaces on my access layer switch say (1-48) with the above config, what will I need to do for the trunk ports that connect up to the my core layer 3 switch which does my Routing between the MPLS.

Currently on the 2960 Uplink it would be something like:

interface giga 1/0/52
switchport mode trunk
switchport trunk native vlan x3
switchport trunk allowed vlan nativeVlan voiceVlan dataVlan


-----

That would be my current config on the trunk ports. Would I have to add the following two lines:

mls qos trust cos
mls qos trust dscp

to the trunk interface?



I would like to iterate that same site calling is fine, but intersite calling is where I experience drops and jitter and hence I only need QOS really for the sites. But I am not sure if I have to enable these commands first on the access layer and then on the core layer switches. I imagine that I do not need to trust the qos on the access layer switches, as the frame should still have the priorities listed within it but just ignored by the switch.

Im rambling right now so ill stop here for now.

Thanks for the responses guys.

I am aware that I have to do the QOS trust statements, but was hoping to dive a bit more technically into classifiers / policers if possible.


I.E based on my bandwidth measurements, I figure I need to reserve specifically 1.5 MEG for the MPLS for voice. Everything else can go on best effort session.

Oh and to answer the question of 100 Meg Saturation, we frequently transfer large data files between the two sites. That and all the media streaming that goes through, really chews through the pipe.

Hey All,

I know this may probably be a dead beaten topic, but I need to ask it anyways, mainly cause I have not dived into QOS and just want to ensure I do this right.

Basically we have two sites, connected to each other through an MPLS network by Telus. The Bandwidth on the MPLS is 100 MB.
As per usual during heavy usage the line gets saturated and we start getting loss of voice packets etc.

We are using a cisco layer 3 switch on each side of the MPLS to do our routing: 3750G. These are our core switches. Access layer switches connect to them which are simply layer two switches: 2960G switches.

On our layer two front: two make calls to one another within the same site we have no issues, so I can forgo QOS on this side for now.

What I need is to know which is the best / most straightforward method to prioritize the VOIP traffic on the Layer 3 front.

I can currently set the Priority to 6 and the DSCP value to 46 (I believe that is the expedited QUEUE) within mitel DHCP controller.

Overall I am imaging I will then have to do some sort of qos trusting, but does this come into play on the layer two front or layer 3 front.

I might be scattered a bit, so any guidance / sample code would be most welcome.

Thanks,

Steve
