We are deploying qos configurations for access servers c3560-E switches. We want to know differences between these kind of configs:

Interface GigabitEthernet 0/1
mls qos trust dscp

or

policy-map trustDSCP
class class-default
trust dscp

interface GigabitEthernet 0/1
service-policy input trustDSCP

We have the same doubts about:

Interface GigabitEthernet 0/1
no mls qos trust dscp

or

policy-map DSCPdef
class class-default
set dscp default

interface GigabitEthernet 0/1
service-policy input DSCPdef

If you try to configure service-policy, and you try with "show policy-map interface gi0/1", you can´t see matches in both cases.

We have read both commands (mls qos trust dscp and service-input) are mutually exclusive, but you can config both commands in the same interface.

Somebody could clarify us these issues?

Thanks.
