3750 and queuing tuning

[vmonte]

Hi,

I need to allocate ingress and egress queue of the 3750 depending on the CoS value.

Here are my needs

Cos 0,1 => 10% total allocated bandwidth

Cos 2,3 => 20% total allocated bandwidth

Cos 3,4 => 30% total allocated bandwidth

Cos 4,5 => 40% total allocated bandwidth

Here's the config I want to fix (see file).

If somebody has already worked on "queuing tuning", can he tell me if globally it'll work or not.

Don't find any document explaining the calculation of the different value to have correct ratio.

Thanks in advance

Hi,

AFAIK you need to first map CoS to queue ID and then you can assign bandwidths to different queues according to their wieghts.
