We're monitoring our PMP's and noticed that on the 2 interfaces that show up on snmp one of them shows a substantial amount of Packet Errors/sec.
What would be causing this, it shows up on the interface labelled "Cambium 10/100 FEC" but does not show up on the Interface Labelled "Canopy Multipoint" not sure what the internal difference is for the radio.
Oddly their also may be a bug, as the Canopy Multipoint interface reports itself as a 10mbps interface and the 10/100 FEC reports itself as 100mbps interface?
This isn't going to fly when you guys start duing 40mhz and well over 100mbps per sector, it's going to make a mess of snmp utiization graphs

CSSupport,
What hardware and software and what Ethernet speed are you running?
We are aware of issue with the Gigabit Ethernet driver with the 450 AP, that when it is running at Gigabit it is droping packets on the Ethernet in. The current work around is to run at 100Base-Tx.
Look at the actual ethernet statistics on the radio in question. Are they inDiscards? That's normal burst traffic entering the ethernet buffer. I see it all the time across busy APs. Nothing is broken.
By the way, your graph shows the error rate in 40-50 milli. That is not significant.
If you see CRC errors, that's different. Those are bad and will cause dropped packets with a noticeable throughput hit to the customers if it's something like 5-10 or more per second.
RcvFifoNoBuf is Receive First in First out No Buffer. The buffer on the ethernet interface is full and can't accept anymore packets so it drops them. The most likely cause of this is the RF interface was saturated for a small ammount of thime so the ethernet interface couldn't pass anymore packets to it, its buffer got full and it started tail dropping.
