ASA supported QoS features:

Theese are my notes from this document: http://tinyurl.com/3dmo5ao

  • Policing – Policing is a way of ensuring that no traffic exceeds the maximum rate (in bits/second) that you configure, thus ensuring that no one traffic flow or class can take over the entire resource. The excess traffic is dropped.
  • Priority queuing – LLQ priority queuing lets you prioritize certain traffic flows (such as latency-sensitive traffic like voice and video) ahead of other traffic.
  • Traffic shaping – is used to match device and link speeds, thereby controlling packet loss, variable delay, and link saturation, which can cause jitter and delay. (not supported on ASA 5580)
