DHCP Option 43 Sub-options

[vandewater]

I'm trying to migrate DHCP from dhcpd to a Fortigate 100D. We have multiple Polycom phones that require several sub-options for option 43. Using the CLI, I've configured the following, but it seems in the DHCP offer, only the first sub-option is included (see attachment). Is this even possible, or am I going about this the wrong way? Any help is appreciated.

config options edit 1 set code 43 set type hex set value "01+BYTES+HEX" next edit 2 set code 43 set type hex set value "02+BYTES+HEX" next edit 3 set code 43 set type hex set value "03+BYTES+HEX" next edit 4 set code 43 set type hex set value "04+BYTES+HEX" next edit 5 set code 43 set type hex set value "05+BYTES+HEX" next end
