Polycom UCS Phone Provisioning DHCP options

[Anonymous]

Hi community

I want to configure the Polycom UCS phone provisioning to be able to mass deploy VVX phones. I want to set the DHCP option 160 with the webserver URL. The problem is: I cant enable this DHCP option for all our devices/clients. I must have a way to give this option only, if a polycom VVX device is the DHCP requestor. How can I do this?

thx and regards

Hi Steffen

Thank you for your answer. I tried the it with vendor specific options for the DHCP, but the problem isn't solved at the moment.I have the following two scenarios:

1. Fill in option 66 with the Provisioning Server Name

2. Apply the vendor specific rules for DHCP and configure the Provisiong Server Name as a DHCP suboption for this vendor specific class

I tried scenario 1 just for a test subnet in our infra. It worked as I expected. The problem is, I can't enable this option for all our subnets, because the option is used otherwise. The only way is the second scenario.

I modifed the DHCP settings to allow the vendor specific rules on our microsoft DHCP servers. I traced the traffic with wireshark and saw the following:

-----------------------------------

DHCP discover:

.....

Option: (53) DHCP Message Type
        Length: 1
        DHCP: Discover (1)
    Option: (12) Host Name
        Length: 20
        Host Name: Polycom_0004f2802ad5
    Option: (55) Parameter Request List
        Length: 11
        Parameter Request List Item: (66) TFTP Server Name
        Parameter Request List Item: (43) Vendor-Specific Information
        Parameter Request List Item: (7) Log Server
        Parameter Request List Item: (54) DHCP Server Identifier
        Parameter Request List Item: (42) Network Time Protocol Servers
        Parameter Request List Item: (15) Domain Name
        Parameter Request List Item: (6) Domain Name Server
        Parameter Request List Item: (4) Time Server
        Parameter Request List Item: (3) Router
        Parameter Request List Item: (2) Time Offset
        Parameter Request List Item: (1) Subnet Mask
    Option: (60) Vendor class identifier
        Length: 14
        Vendor class identifier: Polycom-VVX500
    Option: (125) V-I Vendor-specific Information
        Length: 122
        Enterprise: Polycom, Inc. (13885)
    Option: (255) End
        Option End: 255

DHCP Offer:

....

Option: (3) Router
        Length: 4
        Router: ....
Option: (43) Vendor-Specific Information
        Length: 59
Option: (255) End
Option End: 255

(wireshark shows the URL of my provisioning server in the ASCII code, in the other window I just see Option 43 Vendor-Specific Information and the Lenght.)

-----------------------------------

In scenario 2, I can't see a connection from my polycom VVX-500 to the provisioning server. That means for me, something with the DHCP Vendor specific options does not work as it should....

On the Polycom device I configured for the Provisioning Server/DHCP Settings the following:

Boot Server:                Option66

Boot Server Option:    <blank>

Boot Server Type:      String

Option 60 Format:      ASCII String

Is there someting else I have to configure, to be able to give the Polycom device the Provisioning Server with DHCP vendor specific options?

thx and regards
