Wie kann ich SNOM Telefonen eine andere IP Range per DHCP zuordnen?

Sehr geehrtes SNOM-Support-Team,

wir haben eine Frage:


Ist es möglich, einen Windows-DHCP Server (2003) so zu konfigurieren, dass er

angeschlossenen SNOM Telefonen (i.d.R. Typ 300 - 370) Vendor spezifisch

eine andere IP-Range zur Verfügung stellt, als den restlichen DHCP Clients?


Oder, falls das nicht gehen sollte, hätten sie eine Idee, wie man die IP Bereiche zwische Clients (PCs) und SNOM Telefonen an ein und demselben DHCP Server

auftrennen könnte?

zb. PC-Clients: xxx.xxx.2.xxx

SNOM Phones: xxx.xxx.3.xxx


Wir sind für jede Idee und jeden Vorschlag dankbar.


Beste Grüße,

André

Dear Snom Customer,

The question is two parts:

1: You may configure Microsoft DHCP Server to assign IPs by role:

https://technet.microsoft.com/de-de/library/hh831538.aspx

This method is not recommended unless there is no other option. A configuration with Policy-Based DHCP will grow beyond sustainability for any organization larger than ~100 persons.

OR:

2: You may configure multiple VLANs, and a DHCP pool per-VLAN, with Snom phones living on their own dedicated VOIP VLAN, with DHCP relay. This method is the accepted "Best Practice" standard.

Thanks a lot! 

I´ll  give it a try!


BR,

André

 you are welcome.

The easiest way is to take ISC DHCP-Server (running on an Linux-Computer) and add an simple MAC-based filtering. I do not mean giving fixed IP-Addresses by full MAC, but ISC DHCP can filter i.e. to the company part of the MAC ( 00:04:13:xx:xx:xx for Snom ) and took IP's from an different address pool then it normally takes.

best regards
Micha
