Avaya DHCP Server in SCN environment

[dango510]

I have a few concerns regarding my design and was hoping to get your opinion(s) if this will work or not:

Setup:
4- Locations (a,b,c,d)
R8.0.44
SCN w/ Centralized voicemail -MPLS
4 localized file servers (hosts firmware/46xxsettings file). In Manager each site points to its respective file server
IPO Manager DHCP enabled on LAN1 for every location – distributes IP Address to Avaya Phones only
Each Site is assigned an IP range from its respective voice subnet for DHCP in IPO Manager
Customer also has MS DHCP server, but does not want any “phone programming” on it.
In 46xxsettings file for each file server I will put in the respective call server IP address to allow the phones to register to their respective control unit.

My question is when a phone comes up will it try to come up on the data subnet via the customer’s DHCP server? How do I get the Avaya IP Office DHCP server to intercept and give the phone a voice subnet IP address or will it happen automatically? Or do I absolutely need to have a DHCP Scope 242 in their MS DHCP server?

I am trying to avoid running around to hundreds of phones and statically assigning them in any way shape or form.

I only want Avaya phones to get an IP from our the IPO

Ex.

Data Subnets
192.168.1.0
192.168.2.0
192.168.3.0
192.168.4.0

Voice Subnets
192.168.10.0
192.168.20.0
192.168.30.0
192.168.40.0


If more details needed, let me know...

Thanks,

You can add a rule to the data DHCP server not to reply to DHCP requests based on the full or partial MAC address.
As all Avaya phones share a common part of a MAC address then you can block them on thedata DHCP server.
The Avaya IP Office does the opposite for non Avaya MAC addresses.
If you want to test this you need MAC spoofing on your PC, here is a very nice tool :

It is German but one of the best I have found around the web

I think I have seen at less three different MAC ranges for Avaya phones now (just in 1600's) but it's still possible to do, just a couple more entries

to the OP i am pretty sure you will still need a 242 string on the Data scope to force the phones into the correct VLAN. i dont really know of a way around that. Maybe LLDP but i havent had good luck with that.

Customer also has MS DHCP server, but does not want any “phone programming” on it.

Perhaps they shouldn't ban something when they don't know exactly what's involved, a string of text that the phones read only upon boot is hardly going to have any impact on the server and doesn't exactly constitute "phone programming", it's going to be the best option

Thanks all, yeah I was trying to understand even if we use MAC Spoofing, how would it roll to the correct VLAN? They were 9608 phones BTW. Any complications if all 4 IPO units on SCN are using the DHCP server? They of course would each have their own unique IP range.

What would my DHCP 242 scope need to look like then? This would go on each on each of the data scopes they have built,respectively.

data1.1
MCIPADD=192.168.10.1,MCPORT=1719,HTTPSRVR=192.168.10.2,VLANTEST=0,L2QVLAN=10,L2Q=1
data2.1
MCIPADD=192.168.20.1,MCPORT=1719,HTTPSRVR=192.168.20.2,VLANTEST=0,L2QVLAN=20,L2Q=1
data3.1
MCIPADD=192.168.30.1,MCPORT=1719,HTTPSRVR=192.168.30.2,VLANTEST=0,L2QVLAN=30,L2Q=1
data4.1
MCIPADD=192.168.40.1,MCPORT=1719,HTTPSRVR=192.168.40.2,VLANTEST=0,L2QVLAN=40,L2Q=1

Site 1
192.168.10.1 - IPO
192.168.10.2 - File Server
VLAN=10

Site 2
192.168.20.1 - IPO
192.168.20.2 - File Server
VLAN=10


Site 3
192.168.30.1 - IPO
192.168.30.2 - File Server

Site 4
192.168.40.1 - IPO
192.168.40.2 - File Server


I suppose it's are only option, otherwise I have to manually assign all the phones...blah!

Just this

VLANTEST=0,L2QVLAN=10,L2Q=1


Take Care

I have always wished that my computer would be as easy to use as my telephone.
My wish has come true. I no longer know how to use my telephone.
