pppoe rejects value?

Hi guys.

I have a wireless network with 253 clients, our router is a RB3011, we have all of thew with pppoe auth, our AP are Ubiquiti RocketM5(5)+RocketM5-AC, our clients are NanoLocoM5, LiteBeamM5, LiteBeamM5-AC.

We are working to get what is causing that some clients are connected but other get disconnected and have issue trying to connect to our MK-pppoe server.

My doubt right now is this info I get from mk-radius: /radius monitor, my concern is rejects value, is high or normal in a network this size? Please see my image.

Last thing, what is simultaneous qty of auth users support (+/-) this MB ?

The license is 500 tunnels, but is the same value for Simultaneous?

Thanks.

Reject represents the number of Auth-Reject packets received from the AAA server.

You’ll need to look at the AAA logs to determine why auth requests are rejected by the AAA server.
