Switch not forwarding RADIUS Packets

f1ps1
Level 1
Level 1

I have a 2900 Cisco switch running version 16.12.02 and I'm trying to set up RADIUS for the first time.

I have a RADIUS server at 192.168.0.1 (ports: 1812/1813)

My switch VLAN is at 192.168.0.3

My client is at 192.168.0.2

 

When I do a

$ radtest user pass 192.168.0.1 0 testing123

from the client directly to the RADIUS server, my request gets accepted.

 

Also, the AAA test succeeds:

radius1# test aaa group radius server 192.168.0.1 user pass legacy
Attempting authentication test to server-group radius using radius
User was successfully authenticated

But somehow, the switch is not forwarding my RADIUS packages. From my understanding of 802.1X and RADIUS, I have to send a request from the client (192.168.0.2) to the switch (192.168.0.3) and the switch forwards this packet to the server (192.168.0.1)

But when I send my RADIUS packets to the switch, nothing happens...

$ radtest user pass 192.168.0.1 0 testing123
... output
(0) No reply from server for ID 173 socket 3

This is my output from sh aaa servers:

This is my RADIUS configuration:

aaa accounting dot1x default start-stop group radius
aaa session-id common
dot1x system-auth-control
interface GigabitEthernet1/0/1
 switchport access vlan 99
 switchport mode access
interface GigabitEthernet1/0/3
 switchport access vlan 99
 switchport mode access
interface Vlan99
 ip address 192.168.0.3 255.255.255.0
ip radius source-interface Vlan99
radius server radius1
 address ipv4 192.168.0.1 auth-port 1812 acct-port 1813
 key 7 ***

Any ideas, how I can make the switch forwarding these packages?

Thanks, Philipp
