I am not able to ping Radius Servers from WLC (Mobility Express)

Hi everybody;

I have the following question, i just installed and configured WLC controller with 7 AP's, the management interface have the ip address 192.168.10.90. i am able to ping the interface vlan 10 (internally is the management vlan) of switch 1 (192.168.10.22) and even i am able to ping from WLC whatever ip address from managament vlan of all of devices of my network. I tried to ping my radius server 10.102.100.1 too, but in this case i am not be able to.

On switch 1 i can ping the radius ip address 10.102.100.1 , and also i tried ping 10.102.100.1 source 192.168.10.22 and i can ping.

What could it be the problem??

Is there something wrong?

If i connect a Laptop Directly to the switch in vlan 10, i am able to ping to whatever side.

The switchport configuration is the same like i put in the scheme.

I think the problem it should be here:

(Cisco Controller) >show system routeKernel IP routing tableDestination Gateway Genmask Flags Metric Ref Use Iface0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 srcr37.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 srcr3192.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 virtual

What is your opinion??

What it should be the command to configure routes??

Kind regards.
