Hello, I´m on a network witha lot of switches, I configured auto QoS on non C2950 SI, but now I need to configure
Queueing and Scheduling on those, because they do not support auto QoS. Witch command can I use to to this, and
how I can check if is working later?
What version of IOS are you running? Have you taken a look at Configuring QoS on page 553 of this guide? http://www.cisco.com/en/US/docs/switches/lan/catalyst2950/software/release/12.1_22ea/SCG/2950SCG.pdf
Cisco Internetwork Operating System Software
IOS (tm) C2950 Software (C2950-I6Q4L2-M), Version 12.1(22)EA4, RELEASE SOFTWARE (fc1)
I read, but it´s telling me about Auto QoS, but does not support this command.
Do I need to uplink ports in trust state? The others switch is configured as dscp, but this version on my switch also does not support that, do i need to use de command: mls qos trust cos pass-t dscp
or I just use: mls qos co ?
Here is config from one of my 2960 switches with Autoqos enabled.
mls qos map cos-dscp 0 8 16 26 32 46 48 56mls qos min-reserve 5 170mls qos min-reserve 6 85mls qos min-reserve 7 51mls qos min-reserve 8 34mls qos!

See if you can run through the global commands and then the commands on the switchport. These are the commands that AutoQoS adds. It might not work due to different model and IOS but its worth a try.
You should not need to configure any QoS on a switched LAN.
The is no congestion on LAN,so QoS is not necessary.
Especialy the scheduling and queing commands only generate confusing configuration, while the defaults are perfectly adeguate.
