RE: QoS default port trust state question

It is untrusted unless you configure some level of trust, like:
mls qos trust dscp

If you simply issue "mls qos" globally, this is the port state before
issuing any other qos changed to the port.

Rack1SW3#sh mls qos int f0/1
FastEthernet0/1
trust state: not trusted
trust mode: not trusted
COS override: dis
default COS: 0
DSCP Mutation Map: Default DSCP Mutation Map
Trust device: none

Subject: QoS default port trust state question

Hello,

I'm confused about the default port trust state of different switches ?

Does this depend on the switch (or module) or is it always untrusted ?

Is there a way of finding out what the default port trust state is on a
particular switch ?

I know that for the Catalyst 2950 the default port trust state is
untrusted
