Help with DHCP Vendor Class ID's

Help with DHCP Vendor Class ID's



Hello All,



I am looking for some help with setting up some vendor classes for IP Phones
being placed on the LAN network and users using other IP Enabled devices and
having the DHCP Server place them in another Subnet.

I have never configured vendor class and not even sure if this is what I
might need but it seems this would be the most logical method to dynamically
issue these devices IP Addresses w/o having to set a reservation for each.



What is knows about the devices?

I know that each "vendor" is allocated a unique three-octet this much would
be a constant for the devices placed on the LAN. How do I setup (step by
step, I am new at this) to get DHCP to issue them addresses into another
subnet.



My Network: I have my network with a 4 class C subnet type but only issues
IP to the one Class C.

Example:

10.100.1.0 This network I use for servers

10.100.2.0 This is what DHCP issues to clients whom need addresses

10.100.3.0 This network is used for printers / but can be used also
for the IP devices that are now in my 10.100.2.0 network.

10.100.4.0 I use this network for VPN Users



Any Suggestion would be appreciated

Its been awhile since I have done this, but I can tell you what little I
remember. I used the Vendor class ID with our IP phone system at set up time
to cause my DHCP server to ignore tagged frame requests that had this ID.
That allowed the phones to receive addresses only from the phone switch
which was set to ONLY issue addresses to tagged frames carrying this ID.

Look in your DHCP server. If you right click on the server name, you will
see where you can add user and vendor classes. Add the class here as given
you by your telephone system vendor. Then you can right click on Scope
Options and Advanced and you will see the option you added. You can select
and double click the option here and set its data. For instance a Mitel
system requires that you set Options 130,132, and 133, and the vendor
provides the value for the option. Any server quality NIC should be able to
recognize tagged frames, but if you have a cheapo NIC in there, you may want
to get a better one. Hope this helps!

I am sure the server NIC is capable, now it's a matter of obtaining the
vendor class info for the Phones. I would also like to apply this to VMware
guest OSes where many people use VMware and have them placed on a separate
subnet

So I guess my question next will be: Where can I find the vendor class info
for these devices?

I got the vendor class info for my system from the company that sold it to
me, because they knew it off the top of their head. It was also in the set
up procedure manual for our system. I later found it there, buried in the
information tables in the back.
