Quick Start
Setup using a DHCP server on Unix/Linux
The following snippet from a DHCP configuration file (usually dhcpd.conf) shows how to set up 
a configuration using a vendor class and the "vendor-encapsulated-options" option.
class "OptiIpPhone" {  
   option vendor-encapsulated-options 
   # The vendor encapsulated options consist of hexadecimal values for 
the option number (for instance, 01), the length of the value (for in-
stance, 07), and the value (for instance, 53:69:65:6D:65:6E:73). The 
options can be written in separate lines; the last option must be fol-
lowed by a ’;’ instead of a ’:’. 
   # Tag/Option #1: Vendor "Siemens" 
   #1  7  S  i  e  m  e  n  s 
    01:07:53:69:65:6D:65:6E:73: 
   # Tag/Option #2: VLAN ID 
   # 2  4  0  0  0 10 
    02:04:00:00:00:0A; 
   # Tag/Option #3: DLS IP Address (here: sdlp://192.168.3.30:18443) 
   # 3 25 s  d  l  p  :   / /  1  9  2  .  1  6  8  .  3  . (...etc.) 
    03:19:73:64:6C:70:3A:2F:2F:31:39:32:2E:31:36:38:2E:33:2E:33:30: 
3A:31:38:34:34:33; 
   match if substring (option vendor-class-identifier, 0, 11) =  
   "OptiIpPhone"; 
}

Using Option #43 "Vendor Specific"
Alternatively, option #43 can be used for setting up the VLAN ID and DLS address. The follow-
ing tags are used:
Tag 1: Vendor name
Tag 2: VLAN ID
Tag 3: DLS address
Optionally, the DLS address can be given in an alternative way:
Tag 4: DLS hostname
The Vendor name tag is coded as follows (the first line indicates the ASCII values, the second 
line contains the hexadecimal values):
