Hello,

We are in the process of upgrading our current Cisco Catalyst 3560 Series POE switch to a Cisco Catalyst 2960 Plus Series SI POE.

The config below is what we have in our current switches
 when we try to transfer the config to the new switch, we get an error on the line below:
 
mls qos trust cscp

it does not like cscp, its not recognized. if I change it to COS it does not take,

my question is why it does not take cscp and what the difference is between CSCP and COS. We run voice over ip phones on these switches. the phones and phone system are Siemens.
