Hello everyone - I have been looking at QoS on a WAN router and wanted to throw this topic out for discussion... I have a WAN router (3945) that is connected to a MPLS network with an ethernet handoff. The physical connection to the router is on G0/1 and is connected at 100/Full. The connection speed provided by the ISP is 50M. I have a QoS policy already defined that I need to apply which accounts for voice, video, critical apps, etc. So...my main question is - is there any difference in the following two methods of applying that QoS policy: 1. Set bandwidth statement on G0/1 to 100M and then apply a parent shaping policy to 50M with a child policy calling out my QoS policy. or 2. Set bandwidth statement on G0/1 to 50M and then just apply my QoS policy ?? Is there any difference? Is one of these considered a best-practice approach? Sanjay

I have a question on when to use private VLAN trunking. I have read when trunking to a device that is not PVLAN aware, you should use PVLAN trunking. If you are trunking between devices that are PVLAN aware the you should use regular trunking. What it doesn't tell me is why. Why do we need to use private VLAN trunking?? If the PVLANs are tagged using dot1Q then what is the purpose of using PVLAN trunking - it is not clear what is gained. Thanks in advance...
