About QoS configurable thresholds...

[SIMMN]

Hey,

I was reading through QoS guides and got confused about the threshold things.......

According to document,

you can use following command to configure maximum memory allocation for egress queue.

mls qos queue-set output qset-id threshold queue-id drop-threshold1 drop-threshold2 reserved-threshold maximum-threshold

you can use following command to configure allocated memory for egress queue.

mls qos queue-set output qset-id buffers allocation1 ... allocation4

So now questions:

1. Why queue-set? There will be 4 queue for egress anyway...

2. If queue-set is useful feature, Why no queue-set for ingress?

3. Why multiple thresholds? For ingress, there will be one threshold per queue.

4. When is drop-threshold1 used? When will drop-threshold2 used?

Thanks,

/S

So either everyone is confused as I am OR I confused everyone with my questions and no one bother to ask...
