6900 series phones and DHCP from Linux

[Billz66]

has anyone had any DHCP issues with 69 series handsets for MiVB 8.0 SP3?

customer wants to use linux as DHCP server (Ubuntu)

I have been doing some testing and a 5320 phone responds to my option 43 straight away , the 6920 phone seems to ignore it
( have also tried with option 125 and tried setting as text instead of string)

This config is just a test config as i dont have a local pabx so am testing with MBG address

option MITEL_43 = string
subnet 192.168.90.0 netmask 255.255.255.0{
range 192.168.90.40 192.168.90.45;
option routers 192.168.90.254;
option MITEL_43 = "id:ipphone.mitel.com;sw_tftp=xx.xx.xx.xx;call_srv=xx.xx.xx.xx";
}


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

I believe that you have to have DNS in there for the 69XX series.

I can't think why linux should be any different than windows

I've given up on Option 125 and pretty much exclusively use 43

Here is what I provide my customers

The configuration string will vary for every instance, but there are common patterns and they are fairly well described in the Mitel documention.

Mitel string looks like:

id:ipphone.mitel.com;sw_tftp=xxx.xxx.xxx.xxx;call_srv=xxx.xxx.xxx.xxx;vlan=??;l2p=6;dscp=46​

[pre]
id:id:ipphone.mitel.com = vendor class (Mitel Specific)
sw_tftp=xxx.xxx.xxx.xxx = TFTP Download IP Address - Typically the 3300 controller
call_srv=xxx.xxx.xxx.xxx = 3300 controller address
vlan=?? = the vlan for the phones
l2p=6 = Layer 2 Priority should be 6 but sometimes 5 on Cisco Gear
dscp=46 = Layer 3 priority[/pre]

If the phone cannot acquire it's vlan via LLDP or CDP then the option must be set on both the default LAN and the Voice VLAN

It didnt make sense to me either why linux wasnt working .
I have been sidetracked on other things so havent had a chance to follow it up.
Customer has been steered towards using the MIVb as the DHCP source.

Any MSL based system is Linux and can do the DHCP.
So set one up and check in the Linux part what is needed for this.


BAZINGA!

I'm not insane, my mother had me tested!
