Mitel phones 5320e DHCP Issue

[Tech Electronics]

Johnp,

I kind of figured that was where you were going, but we can't do that on the 5000. I was knocking your answer either, I just wanted to clarify my original post as to why I asked about LLDP-MED or CDP.

Thanks,

TE

Kind of like why I put the LLDP-MED question, when answered it does LLDP  Didn't think you were knocking me, just wanted to add the additional info to clarify.

It is more difficult to answered such a question when doing it from memory without anything open to referrence. Know how to do it, even figured out option 125 on a linux DHCP box years ago when they first moved to it instead of the 128 etc options.

Johnp,

We don't even try to setup a customers DHCP server anymore as it is always a headache. This way if their DHCP server has an issue the phone will still be ok.

Now, what we normally do is set at least one of the answer point phones to be a static IP address so that if the DHCP server on the 5000 has an issue we at least have one phone still working.

Thanks,

TE

So to clarify

I have my DHCP server running in VLAN 1 untagged. If I plug a comptuer into vlan 2 i get a 9.0 IP if I plug a comptuer in vlan 1 i get a 0.0 IP.

My phone system right now is in the 0.0 network

When I plug my phone into the VLAN 2 Tagged port  it boots but it ignores everything and just pulls from our old DHCP server.

When I disable the old DHCP server and it is forced to pull from our new one. It tells me option 129 is missing.

If only I could get the option 129 to work.

May I also add that it is ignoring the option 43. It just strait up says no vlan when booting. It once said VLAN2

If you are using untagged switch ports then you don't want to use a vlan option for the phone otherwise it will tag the packets and hang.
If you are tagging the voice vlan on the switch then you would specify a vlan in your options if not then treat it as if there are no vlans.

Try this:
Plug the phone in and hold down the 7 key until “Config Teleworker?” appears
Press * for yes
Press # for new
Enter IP address of PBX (Using # for . if needed)
Press the volume down key to save.
Press * to save changes and reboot phone.

This will bypass Mitel specific options and use normal DHCP like a PC would.

The difficulty with option 125 and Windows Server is that it is an encapsulated option and isn't programmed directly from the gui.
Check the attached guide to get you started and use the Config Helper to get you started.

Does the Mitel 5000 support multiple gateways or routes?

[Tech Electronics]

cgashlin01,

What exactly are you referring to; what are you trying to do?

Thanks,

I may just wait until a weekend to adjust all the IPs. since my mitel does not have the correct gateway in for the new VLAN I cannot connect to eh Mitel from the 9.1 network. I will have to try once I adjust the gateway on the Mitel.

cgashlin01,

Ah, I get what you were trying to do now. Unfortunately the 5000 allows for only one gateway. If you do change it then you will need to do a reset after performing a backup database save.

Thanks,

Oh fun, ill have to schedule the reboot.

Hopefully my DHCP works after the reboot and can supply the phones. If not another headache will occur.

cgashlin01,

That is why we don't use third-party DHCP servers, too much of a headache. Not sure why you want to recreate the wheel, but we are here to help if we can.

Thanks,

To make things really awesome. Now all of my 5320 phones are pulling weird stuff.

They are booting up and thinking they are on VLAN 2 then just sit there at DHCP: Discovery. I have no VLANS currently. I removed all of them. LLDP is disabled on everything. It is back to what it used to be.

Funny thing.....
If I plug into another switch it works.

[cgashlin01]

Turns out LLDP is scary. it some how replicated to the POE switch and was telling it to look on VLAN2. SURPRISE!!!!

cgashlin01,

That is one of the issues of working on a live system. Welcome to the club!

Sorry,
