Mitel 5330E No address using Voice Vlan

[HARTNETT]

I am using a Cisco Catalyst 3750X switch on a Mitel system that is not resident to the office. We are using a 3rd party to switch our calls. I can plug the Mitel phones into an unconfigured switch and get an IP address. If I configure the port for a Voice VLAN the phone does not get an address. If I use option 43 or 125 where do I get the sw_TFTP and call_srv addresses from, since we do not have a phone system in the office?
The phone gets an address with VLAN 1 but not with the voice VLAN.

you need an ip helper in the voice vlan pointed at the dhcp source for the voice vlan

in that dhcp source you will need the coorect options that will direct the phone to the pabx for tftp etc

If I never did anything I'd never done before , I'd never do anything.....

 

[HARTNETT]

That's what I cannot figure out. The phone boots to vlan1 with nothing set. It gets all of the info over the internet from the phone service provider. As soon as I put the phone on a port other than vlan1 it displays the vlan number that it is on, and never gets an address from the dhcp.

Reading between the lines I feel you've missed a few steps in your design change.

Considering that you "do not have a phone system in the office", how is Vlan 3 supposed to route to a controller elsewhere?

[HARTNETT]

The Mitel system is hosted. The purpose of the Vlan was to separate the PC traffic from the phone traffic. It works on an unmanaged switch, but not on a managed one. If there were 2 Ethernet cables per desk I would just setup two different networks. Unfortunately that's not the case. I have set up the ports per Cisco instructions but it still will not work with a voice Vlan.

 

[kwbMitel]

Sorry HARNETT, it's not that I don't understand what you are trying to do. In fact I know it all too well. It's just that you are not providing enough information.

i.e. You say that you get DHCP on vlan 1 but you do not say if the phones actually work on Vlan 1 or how they route via vlan 1 back to the controller. You want to separate Voice and Data, I get it. Vlans are layer 2. If you do not have a local controller, you need layer 3 routing, where is that? As Billz66 said, you need a DHCP helper command to tell the subnet on VLAN 3 where to get it's DHCP for that subnet (or you need one specifically setup to respond to broadcast traffic within that Vlan. Have you even considered that you need a new subnet for Vlan 3, I don't know because you haven't told me. The scarcity of the information you are providing is an indication that you either have not fully designed your solution or you do not not know how.

Perhaps they are teleworker phones ?
reboot one holding down 7 and go through the menu , if it has a teleworker address
then do that for the other phone and set the same address

If I never did anything I'd never done before , I'd never do anything.....

 

[kwbMitel]

At Billz66, that assumes VLan3 is routable to the internet.

Also, he's already stated no DHCP in VLAN3 so TW routing won't really help much

[HARTNETT]

The phones work in Vlan1. A windows server is the DHCP and a Linksys router connects us to the internet.

 

[kwbMitel]

@HARTNETT - It's getting to the point of diminishing returns. I can't help you if you keep holding back information

WHAT HAVE YOU DESIGNED ON VLAN3 TO ALLOW ACCESS TO THE INTERNET AND TO PROVIDE DHCP!

The voice Vlan is 20 not 3. When the phone is on the 3750X switch in its default state( which is vlan 1) it boots to the hosted phone system. The phone waits for LLDP then does a Discovery then displays VLAN NONE PRI NONE and boots to the phone system.
I configured Port 24 (which is connected to the router $ the DHCP server) as a trunking port with VLAN 1 & VLAN 20 and it still works.
I then configured port 1 which is where the phone is connected to :
switchport voice VLAN 20.
IP helper address of the DHCP Server.
I reboot the phone. It waits for LLDP then does Discovery than displays VLAN 20 PRI 5 3 0 then justs sit there.

I set up port 2 as:
switchport trunk encapsulation dot1q
switchport trunk native VLAN 1
switchport mode trunk
switchport voice VLAN 20
Plugged the phone into port 2 and rebooted and I get the same results as above
It waits for LLDP then does Discovery than displays VLAN 20 PRI 5 3 0 then justs sit there.

Ok, getting somewhere

DHCP needs to come from somewhere, it does not simply work. You need to design a scope for DCHP to provide IP addresses on Vlan20. Additionally, unless the DHCP server is specifically visible to Vlan20, you will need to use an IP Helper command to route the Broadcast traffic to where the DHCP server is visible.

You say the phones are stuck on DHCP. Yes, of course they are as you are not providing DHCP within the Vlan.

[HARTNETT]

The windows server is the DHCP. The ip helper address is pointing to the DHCP server address. I set VLAN 20 to the ip address of the default scope of the DHCP 10.10.10.1. The DHCP scope is 10.10.10.11-10.10.10.59. The server address is 10.10.10.2 & the router is 10.10.10.10

 

[kwbMitel]

If I am understanding your last, it sounds like you are trying to use the same scope for both Vlans.

I'm not sure that is possible and definitely is not the intent of using vlans.

Each Vlan should have it's own scope and separate IP address range

[HARTNETT]

I do have 2 different scopes, but it is the Voice VLAN that is giving me the trouble. The other scope is 10.10.11.1 - 10.10.11.20. It doesn't make a difference what the scope is the, Mitel phone will not get an address when associated with the Voice Vlan.

 

[sarond]

Does your switch have an IP address in both VLANs?

 

[kwbMitel]

Ok, at this point I'd be putting a laptop on the voice vlan to prove that the issue is with the DHCP Server.

I think you feel it is the phone acting strangely, I find that quite unlikely.

[HARTNETT]

You are right, I thought it was the phone but it has to be something with my whole setup. I reset the switch and created 4 VLANS. I setup 4 ports with switch access mode, no voice. I set up 1 trunk port for the router. I connected a desktop with a static IP, on one of the VLAN ports, and could not ping the router. I then connected the router to a port that was on the same VLAN as the desktop, and I could ping it. I cannot get traffic from any VLAN port to the trunk port. That's where I am. I am now convinced it is not the Mitel phone.
Thanks

Is your router configured correctly with an IP in each VLAN and 801.2q capable (vlan tagging)
Maybe you could post some config details of your switch and router.

 

[HARTNETT]

Port 24 which is configured as a trunk is attached to the router. It was set up
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk allowed VLAN All

That did not work.
I found another Cisco paper that had me do the following to port 24:

No Switchport
IP address 10.10.10.9 255.255.255.252
This gave the port an address.

This allowed the devices on the VLans to access the DHCP server and get an address
I also had to use the following command so that the devices could access the Internet

IP route 0.0.0.0 0.0.0.0 10.10.10.9

Of course everything worked except the Mitel 5330E
The phone now gets the initial address from the DHCP, but then says ADD GATEWAY.
The 003 Router Scope is set to the router 10.10.10.10, but it still says ADD GATEWAY in an endless loop.
Any suggestions?
