Has anyone ever setup a Mikrotik router with option 43 in DHCP to send Wi-Fi controller ip addresses to bluesocket ap's? I've been working this for some time and can't get it to work.
I am thinking it's not possible because of the VCI string. Appreciate any thoughts on this.
-BSAP Instructions-
Configuring DHCP Option 43 in Your Organization’s DHCP Server
When a BSAP sends a DHCP discovery message to obtain an IP address, it includes DHCP Option 60. DHCP Option 60 is the vendor class identifier (VCI). The VCI is a sting that identifies the BSAP to the DHCP server. The VCI used by all BSAPs regardless of model is BlueSecure.AP1500
Vendor-Specific Information
On the DHCP server, the vendor-specific information is mapped to the VCI string. When the DHCP server sees a recognizable VCI in a DHCP discovery message from a BSAP, it returns the mapped vendor-specific information in its DHCP offer to the BSAP as DHCP Option 43. On the DHCP server, Option 43 is defined in each DHCP pool that offers IP addresses to the BSAPs.
RFC 2132 states that DHCP servers must return vendor-specific information as DHCP Option 43. The RFC allows vendors to define encapsulated vendor-specific options. The encapsulated vendor-specific options are all included in the DHCP offer encoded as a sequence of code, length, and value within
Option 43. The definition of encapsulated vendor-specific options is specific to the vendor.
When DHCP servers are programmed to offer vWLAN public network interface IP addresses as Option 43 for BSAPs, the encapsulated vendor-specific options are defined in the following manner:
Code: 127 (in decimal format)
Length: A count of the characters of the ASCII string in the Value field (in decimal format)
Value: ASCII string that is a comma separated list of primary vWLAN public network interface IP
addresses followed by secondary vWLAN public network interface IP addresses. Secondary VWLAN
public network interface IP addresses start with F, denoting failover. No spaces should be embedded in the list.
Example DHCP Option 43 Code, Length, and Value
The following is sample information for the code, length, and value of DHCP Option 43:
Primary vWLAN public network interface IP address: 192.168.130.1
Secondary vWLAN public network interface IP address: 192.168.130.2
Code: 127
Length: 28
Value: 192.168.130.1,F192.168.130.2
You never say what your having a problem with, this is a pretty typical setup. What your trying to do is covered in the mikrotik documentation.
Hi, thanks for answering my post.
The issue I'm having is I can't get the WiFi controller address to the AP, it gets an IP address from the dhcp pool no problem, but no go on the controller addresses. I've followed the instructions, and tried several variations. At first, I tried converting the ip information to hex manually, which did not work either. Then figured out that MikroTik converts it for you. This is what I think it's supposed to be:
/ip dhcp-server option> print
NAME CODE VALUE RAW-VALUE
0 BlueAP 43 '-------------,F-----------------' 36-----------------------------------------------------..
The addresses in the code value are the controller addresses. the F is supposed to indicate a backup server in case the first one fails.
I've tried just entering the first address, no go.
I also added the "BlueSecure.AP1500" to the Vendor Classes tab. Didn't work.
I tried adding "BlueSecure.AP1500" as an option60, No go.
I am starting to think there may be an issue with the AP's, but I am told that option 43 is supposed to work with them.
Thank you for any insight.
