Hello, I'm working on Vol2 Lab8 QoS section. Task 5.2 requires to conditionally trust DSCP markings from the Cisco IP phone, which can be accomplished with:
mls qos trust device cisco-phone mls qos trust dscp But 5.3 requires policing and remarking using service-policy for the same switch port. In the Enterprise QoS SRND page 106 we have: At the time of writing, the Catalyst 2970/3560/3750 does not support a trust statement (such as mls qos trust device cisco-phone) in conjunction with a service-policy input statement applied to given port at the same time. While this may be configurable, if the switch is reset, one or the other statement may be removed when the switch reloads. This limitation is to be addressed; consult the latest Catalyst 2970/3560/3750 QoS documentation for updates on this limitation PG's solution seems to ignore this fact. What's your opinion on this? I was unable to find anything on this in the archive. BTW, how can I find QoS SRND via cisco.com documentation portal? regards kobel
