Massive Syslog Messages for RADIUS Accounting

Massive Syslog Messages for RADIUS Accounting

Hi there,

we discovered some Switches are sending "RADIUS Accounting Errors" to our NetSight. They are look pretty much like this:

AAA[13]RADIUS Attempted the configured number of retries (3) to accounting server #2 without a server response for 00-XX-XX-XX-XX-XX (username '00-XX-XX-XX-XX-XX') on port tg.13.3

The most messages are from our bonded S8-Chassis, which obviously got the most users connected.

The Server "number" varies as well as the ports, but all of our 5 NAC Gateways are up and running... and we don't see other errors on the network.

The switch sends about 20-30 Messages every few minutes.

Does anyone know what this Messages could cause or exactly mean?

Thanks in advance,

Martin

This is our RADIUS Config:

I'm not an expert on RADIUS accounting but could you check whether it's it enabled on the NACs ?
