radius-server timeout <<- can you change this timeout
the retransmit meaning and all you mention before about many hop to Server, lead me to think that there is issue with SW-Server timeout, and debug show us that,
so please make timeout long enough.

I dont get it ?

Different network than RADIUS Server. RADIUS Server is in network 137. But I'm able to ping from Network 132; however Clients from that network got Access Denied.

the client not direct connect to radius server,
the SW or Router is connect to radius, the Q what service you run here ?

post a diagram of your topology showing what devices are involved, and how the devices are connected.

this is connectivity issue between SW and AAA server,
ping <AAA IP > source <VLAN IP>
check if the ping is OK if not, I think you need
1- specify the source of AAA packet in SW
2- config default GW in SW
3- config static route for server.
last point, how you config two link to Server via vlan 99 and in same time each vlan have different subnet. ?

I'm able to ping from source to Server. Both subnets belong to the same domain.
01-13-2023 02:43 PM
And same radius group
01-13-2023 02:46 PM
can I see the success ping ? what commend you use ?
01-13-2023 06:37 PM
ping from Sw 137...
Type escape sequence...
sending 5, 100-byte ICMP Echos to .... timeout is 2s
success rate is 100 percent (5/5).... 1/1/1 ms
ping from Sw 132
same result difference is at the end 76/76/77 ms

Yes but I suggest to use source with ping,
this source is same IP you add in AAA server.
this make us sure that there is connection between specific VLAN and server
01-14-2023 03:21 AM
Yes. VLan99 is the management VLan and when I ssh to it, I use that source IP
01-14-2023 06:46 AM
I make small lab,
the tacacs server add SW VLAN 99 SVI IP as device IP
now you can see that ping from SW to server is success
but ping with source vlan 99 is failed !!
are the SW is L3 SW via ip routing command ?
are the SW is use separate Router for inter-vlan ?

ping from source VLan99 was a success.
SW are C9300s so they're L3. We're not using ip routing for RADIUS
