Assign correct VLAN-ID to OpenStage IP-Phone

Hello, I'm looking for some advice.

I'm trying to assign a VLAN-ID via Option 43 (?) to IP-Phones.

The Reason for that is that the Switch can´t deliver a VLAN-ID, so the Phones should boot into a wrong subnet and get told the right VLAN-ID by Infoblox.

As soon as the Phones have the right VLAN-ID they will disconnect automaticly and connect to the right VLAN.

Can somebody help me?
Thank you David

Hi David,

 

The information to configure Option 43 on your Infoblox DHCP servers should be provided by your IP Phone vendor as this is vendor specific. I have been able to find the following information about VLAN-ID discovery using DHCP and configuration and use of Option 43 for Siemens Optipoint and Openstage phones.

If this link is not helpful , I would recommend to open a support ticket with Infoblox Support.

Thank you for your answer,
 
I've already tried to implement this solution, but did not succeed.
I am not quite sure how to enter the data into the Infoblox. In the instructions, only the procedure for a MS DHCP is explained.
I have tested the following settings for VLAN 13:
DHCP: vendor-encapsulated-options (43): 13
DHCP: vendor-encapsulated-options (43): 01 00 00 00 0d

You have to define a custom option space, use it in an option filter matching option 60 and apply it to dhcp pools used during boot. Here are some screenshots to get you running.

Hello ABodartX, 

 

I've created Option Scope and Option IPv4 Filter, and now what Option I must to define on DHCP Scope? 43 0 60? And what is the string?

 

Thanks a lot.
