Our client has MPLS connected all sites. Each site has a router connected to MPLS via serial interface,
and connected to the switch (6500) via ethernet interface. There is QoS applied on the serial interface
Q1: It appears there are lots of inbound traffic coming to the site, and the client applied QoS on outbound
What I learned that after the packet are marked by the CPE, the ingree Provider Edge Router (PER)
uses these marking to map flows to various Label Switched Paths (LSPs) providing differentiated treatment
accross the network. Then at egree, the PER applies queuing policying based on the CPEs orginal DSCP markings
to properly allocate bandwidth on the egrees link during congestion. My guess we really don't need to have
inbound policy applied in the serial interface on the router, am I correct?
Q2: The serial interface has 1.5 MB, and the goal is we want to have 1 MB for cirtical apps, and 0.5 MB for download/upload
internet access. If we apply this policy on the switch, A) should I apply it on the VLAN interface or the port connected to the router?
B) Should I apply output or input? Any suggestion?
