Please let me know where you were reading that, because that's not the behavior I've observed in real life!
If it comes in as CoS 5, the DSCP will get rewritten (provided you have mls qos enabled and the trust level appropriately set). That will indeed affect other devices. Scott -----Original Message----- From: Suresh Mishra [mailto:[EMAIL PROTECTED] Sent: Thursday, June 05, 2008 5:15 PM To: Scott Morris; OSL CCIE Routing and Switching Lab Exam Subject: LAB 12 task 7 Hello all, This LAB requires that we change the cos-dscp map to map cos 5 to dscp 46. Now this is required for dwonstream routers so that they see DSCP 46 in the IP packet. However i was reading the document , it says that cos-dscp mapping is used internally by the switch and has nothing to do with changing the IP packets DSCP field. In that case downstream routers will not see the dscp value. Can somebody help me out on this issue? Thanks Suresh
