Hi,

When asked to configure outbound traffic, say telnet, on a certain router
interface with an IP Precedence value of 3, I've seen the following
configuration on the connecting switch port, which I dont understand.

interface FastEthernet0/6
 desc Connection to Router R1 interface fa0/0
 *mls qos trust ip-precedence*

What's the purpose of the above "mls qos trust ip-precedence" command on the
switch's port, and if not set, would the switch change the precedence value
that had been set by the router configuration ?
