Re: dhcp vendor classes option

phones subnet is 255.255.255.0, computers subnet is 255.255.248.0,

what is vendor class data type, i use string with code 60, its ok ?
in the string i have ccp.avaya.com

ethereal offer in phone dhcp discover option 60: Vendor Class identifier =
"ccp.avaya.com" - hexa 3c 0d 63 63 70 2e 61 76 61 79 61 2e 63 6f 6d

when i deactivate first scope (computers scope), second phone scope working
correctly.

i know that vlan is better solution but i dont know how i can do it with one
dhcp server ?

79 61 2E 63 6F 6D in scope options table general too but ip phone get ip
address from bad scope :-(

Are your phones on the same subnet as your workstations?

Normally, it is a best practice to put them in their own separate VLAN.
However, I have not implemented an Avaya solution yet, so I'm not sure what
the vendor recommends. I prefer putting IP phones in their own VLAN for
better manageability and security reasons.

hi oliver,

i was unsuccesfull :-(.

How were you unsuccessful? After you create the option, are you able to
see
it in the DHCP Standard Options list?

Oliver

i have 1 superscope with 2 scopes, first is 172.16.16.0/21 for
computers,
second 192.168.12.1/24 is for avaya ip phones. i created predefined
options
in options class - dhcp standard options - code 60, string
ccp.avaya.com (
vendor info is from ethereal)

do you have any proposal or hint ?

thank you

hi all,

i would like to use our main dhcp windows 2003 server for avaya ip
phones
and computers too. i tried to create a separate scope for ip phones
only
with
vendor classes option 60 but without success. can you help me with
it
please ?

thank you

lukas

Hi Lukas,

You need to open your DHCP MMC --> right-click on the name of the
server
that will be hosting the scope for your IP phones --> select
"Pre-defined
Options" --> click "Add" --> enter your vendor information (put the
number
"60" in the "code" field).

Once this option is created, you can use it in your scopes, as needed.

Hope that helps,
Oliver
