Introduction
This feature is an enhancement to the RADIUS accounting functionality. It is ONLY supported on EAP101, EAP102 with firmware version V12.4.0 or later. Any firmware version prior to V12.4.0 will not contain this feature.
In previous RADIUS accounting implementation, the IP address of a supplicant or client is not included in the Accounting Start Request. This causes the RADIUS server not able to log the IP address of a supplicant.
This new feature called “Framed-IP-Address” will now include the IP address of the supplicant in the Accounting Start Request packet. The concept is to wait for the DHCP 4-way handshaking process to complete and the IP address of a supplicant can then be obtained. This feature is enabled by default in V12.4.0 and disabled in V12.4.1 or later.
If using attribute to enable this feature, there will be no “Framed-IP-Address” in Accounting Start packet but will be in Interim Update and Accounting Stop packets.
Flow Diagram
Original implementation (FW ver. 12.3.1 or before) 
FW ver. 12.4.0 – Default Setting
FW ver. 12.4.0 – Behavior can be changed as follows by attribute information
FW ver. 12.4.1 or newer – Default Setting

Configuration
Default Setting
| Feature | Ver 12.4.0 | Ver 12.4.1 or newer |
| Client IP address is included into RADIUS Accounting Start | Default Enabled (Disable through attribute) | Default Disabled (Enable through attribute) |

Enabling and Disabling
- Enable SSH service and login to the device.
- Create a dictionary file such as “dictionary.zvendor”.
- Edit the dictionary file to the format below.
- Add the newly created dictionary file to the RADIUS main dictionary file and save.
- Create an account with the attribute as below.
Explanation:
- Using account “test”:
⚫ In v12.4.0, Accounting Start Request packet will be sent by the AP until Frame-IP-Address obtains client IP address, i.e. client is not able to access the network before the process is finished
⚫ In v12.4.1, Accounting Start Request packet will be sent by the AP with no Frame-IP-Address - Using account “test1” (Framed-IP-Address enabled):
⚫ Accounting Start Request packet will be sent by the AP with no Frame-IP-Address - Using account “testing” (Framed-IP-Address disabled):
⚫ Accounting Start Request packet will be sent by the AP until Frame-IP-Address obtains client IP address, i.e. client is not able to access the network before the process is finished
