aaa radius configuration

[jethro.w.tambeana]

Hi all, i need assistance with my aaa radius configuration. below is my configuration and as per tcmpdump on the accouting server 172.31.34.33, i am not seeing any dhcp accounting packets coming through. my aim is to forward dhcp packets to the accounting server 172.31.34.33. please check my config and let me know my mistake.

Router(config)# aaa new-model
Router(config)# aaa group server radius SSG-SMP
Router(config-sg-radius)# server 172.31.34.33 acct-port 1813
Router(config-sg-radius)# exit
Router(config)# aaa accounting network RADIUS-GROUP1 start-stop group SSG-SMP
Router(config)# aaa session-id common
Router(config)# ip radius source-interface loopback 21 vrf DATA
Router(config)# radius-server retransmit 3
 
radius server SSG-SMP
address ipv4 172.31.34.33 auth-port 1645 acct-port 1646

Router(config)# ip dhcp pool Pool_101
Router(dhcp-config)# vrf DATA

Router(dhcp-config)# accounting RADIUS-GROUP1

Hello,

at first glance, it looks like you are missing the vrf forwarding for the server group:

aaa new-model
aaa group server radius SSG-SMP
server 172.31.34.33 acct-port 1813
--> ip vrf forwarding DATA
