I can´t believe that I am asking this but what the the heck :D A cisco phone connected to a switch.
! switchport mode access switchport voice vlan x switchport access vlan x ! I have somehow considered the phone to send COS layer 2 packets on the voice vlan because the phone is actually trunking (after negotiating voice vlan with cdp) data and user vlan. ! However the port is in access mode (as it looks) and show int status shows that clearly.. ! I have a question in my practice LAB that wants layer2 ports and interswitch links to trust cos and layer3 interfaces to trust DSCP. ! Am I not right to trust cos on the phone port ? even though it seems access it is sending COS layer2 tags on the packets right ? Another bonus question if the phone didn´t have the switchport voice vlan but only a access VLAN it would sit on. Would that still be mls qos trust cos ? regards.
