Hi Rene,

I have a question and may not be related to this section but it is to switches. I have been having latency issues with all my users in one location. We install a new 3560x switch with Access to shares, printing and voip and they are very very slow. I called cisco in regards to checking QOS on my switch, spoke to 2 different Engineers and I got different opinions, I have mls qos statements but QOS never enable so one opinion recommended these settings on the interface:

```auto
srr-queue bandwidth share 10 10 60 20
priority-queue out
mls qos trust cos
auto qos trust

```

and the second opinion was:

```auto
srr-queue bandwidth share 1 30 35 5
priority-queue out
mls qos trust device cisco-phone
mls qos trust cos
service-policy input AUTOQOS-SRND4-CISCOPHONE-POLICY
auto qos voip cisco-phone

```

I also have this command enable: auto qos srnd4 and I have cisco phones.

What is your opinion on this one?
