- LLQ = CBWFQ + “priority” keyword
- You can have more than 1 queue at a time
- PQ can consume 100% bandwidth and starve low priority queue
- LLQ discard traffic when exceed configured bandwidth – Policing!
Double LLQ – 2 policing in 1 queue
1 Video Conference session = 320kbps
3 G.729a voice calls = 80kbps
If you configure “priority 400”, and if you have more than 3 G.729a voice calls, it will affect the video conferencing quality as it will exceed the policed rate 400kbps.
If you have 2 separate class-maps, i.e.
You can’t have more than 1 video conference call or more than 3 G.729a calls as it is policed in 2 difference classes.
