"Note: Any interface that is overdriven (that is, when the offered rate is greater than the line rate) presents output drops.
ATM interfaces typically use ATM-layer traffic shaping to limit the maximum amount of bandwidth used by a virtual connection. If you present more traffic to the virtual circuit (VC) than it is configured to transmit, the ATM interface tries to store the packet until it can be scheduled for transmission. However, the interface may need to drop some packets. This can particularly happen if you burst above the traffic-shaping parameters for a period of time longer than the virtual circuit is configured to handle. Traffic shaping is often implemented as part of a traffic contract with the circuit provider."
It is a 7Mb PVC (Burstable to 14Mb), and I've never seen the txload or rxload get over 9/255 - And our SolarWinds monitoring has never reported anything above 6Mb/sec? Just wondering what could be causing this?
It seems that you have too short TXRing and too short hold queue. Your TXRing for the PVC can fit just 1 Ethernet packet ( 3 particles = 3 * 512 = 1536 Bytes). So after one packet is transferred to TXRing and waiting to be sent all other packets for the PVC goes to hold queue whos lenght is also limited. If packets are coming fast enough hold queue overflows and you get all these discards.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
