We use a 3rd party NAC that integrates with our VX9000. Our NAC was recently under heavy load and we were able to determine the issue was caused by multiple RADIUS accounting records coming from the VX9000 per device. It seems that the VX9000 is sending accounting data for devices every time a device roams between APs (this causes a LOT of accounting data).
- Does this sound accurate?
- Is it possible to have the VX9000 share the accounting sessions between the APs so that roaming between them doesn't generate additional sessions?
