Radius Services on a 7650

[tL888]

We have a couple dozen ICX7650-48F-L3-BASE 48-port's running TNR08095m utilizing the same RADIUS configurations and one of then has decided to stop authenticating via RADIUS.  No changes, no patches, no issues, uptime is approx. 30 days. Packet captures are showing the RADIUS auth traffic on the issue device is not leaving the router at all - compared to packet capture traffic on the working routers.

We re-created the RADIUS clients multiple times, stripped and re-configured the router RADIUS config with the same and new keys, and reloaded the RADIUS servers. No luck.

**Is there ANY way to restart/ recycle the RADIUS services on the router without reloading the router?

Thanks!
