SRX

Hello,

I have an SRX320 and we are moving to a hosted phone provider. They have asked for the following DHCP Options

DHCP Options
Could the following DHCP options by added to the voice VLAN:
 option 66 ascii provision.acuitymt.uk
 option 160 ascii http://provision.acuitymt.uk/app/provision/
 option 246 ascii upfprofile.address=http://upf.acuityuc.com/provision.xml
 option 4 ip 185.192.177.37
 option 42 ip 185.192.177.37

I have configured them word for word on the pool but it is working. Can someone please point me in the right direction?

Many thanks

Barry

Hello,

"ASCII" and "IP" are not valid option types for JUNOS , please see https://www.juniper.net/documentation/en_US/junos/topics/topic-map/dhcp-local-server-for-routing-devices.html#id-creating-user-defined-dhcp-options-not-included-in-the-default-junos-implementation

• option-type—Any of the following types: byte, byte-stream, flag, integer, ip-address, short, string, unsigned-integer, unsigned-short.

Hi Alex,

Thanks for your responce. I just need to get my head around this now. So the below lines wouldn't work?

option 4 ip-address 185.192.177.37;

option 42 ip-address 185.192.177.37;

option 66 array string provision.acuitymt.uk;

option 160 array string http://provision.acuitymt.uk/app/provision/

option 246  array string upfprofile.address=http://upf.acuityuc.com/provision.xml

Array is used when Your DHCP server has more than 1 value to offer, such as 

option 42 array ip-address [ 185.192.177.37 203.0.113.1 ]

Else You don't need array.

And You need to enclose Your strings into double quotes just as in the example at link I provided. 

Finally, some options can have restrictions on types , such as option 43 in this example https://www.reddit.com/r/networking/comments/362sz6/junos_dhcp_server_option_configuration/ so You have to follow these restrictions and convert the strings/IPs into bytes like in this example https://kb.juniper.net/InfoCenter/index?page=content&id=KB23834&cat=SWITCH_PRODUCTS&actp=LIST
