option 60, and expect SmartZone IP information to be provided in DHCP option 43 (Vendor
Specific Info), encapsulated with sub-option code 06 (the sub-option code for SCG in this
example).
The RFC describes how vendors can encapsulate vendor-specific sub-option codes (ranging
from 0 to 255). Sub-options are embedded in option 43 as TLV (type, length, value) blocks.
Ruckus Wireless Access points support non-TLV format option 43 values with comma separated
IP address strings for discovering SmartZones, and also TLV based option 43 encapsulation as
specified in RFC 2132.
Example: for SCG information (sub-option code 06)
Type:
0x06
Length:
Count of the characters in the ASCII string. (Length must include the commas if
there is more than one SCG specified.)
Value:
A non-null terminated ASCII string that is a comma-separated list of SCG IP
addresses.
For example: If the SCG IP address is 10.1.40.25, then the value will be “ 10.1.40.25 ”
and the length is 25 (hex value 0x19 ).
