Over the years using Mikrotik as our PPPoE server I've noticed a strange occurrence... Every once in awhile I'll see a user using well over the defined SLA 4-10Mbps when they're subscribed for say 512kbps. It doesn't really matter what speed they're subscribed for it just happens randomly. It doesn't happen that often and normally I forget to put up a post to see if anyone else has experienced this.
I have the SLA's defined so that they have a MIR of whatever their subscribed for a CIR of a fraction of the MIR (for example 512kbps, has a CIR of 256kbps), and then I have burst limits defined so they can burst up to the next SLA (ex: if they're subscribed for 512kbps they can burst to 768kbps) for 20seconds or 'x' amount of bits. The SLA's are all defined by the RADIUS server and work fine, its just every once in awhile one connection seems to think it's unlimited.
Like I said before it doesn't happen all that often, I catch it maybe a couple times a month if that.
To fix it I just kill their PPPoE session their router reconnects shortly there after and the speeds are back to normal.
Not a big issue, but it would be nice if it didn't happen.
Anyone else experience this issue?
All my PPPoE servers are running the latest stable release 2.9.46. I've started noticing this since ~2.9.40...
