Hi,    I've got a router with a gigabit interface connected to ISP. I bought 30Mbps Point-To-Point Link(Lease-Line) from them. To treat critical applications, I need to shape bandwidth to not above than 30Mbps(gigabit interface) and then treat critical applications by using CBWFQ.     It seems to be work but I've always seen total drops from "show policy-map interface gx/y". I know there are 2 reasons why? 1. WRED 2. I have exceeded the configured queue limit.    I would focus on 2nd reason. Then I increased queue-limet to 32768(Max). But I still see total drops. ######### (queue depth/total drops/no-buffer drops) 0/1112/0 #########    And "show interface gx/y summary" output showed me a couter of OQD: pkts dropped from output queue. ####################################### CHILD: policy-map CHILD class CRITICAL_APP   bandwidth 27000   queue-limit 32768 packets !

What have I missed? TIA Toshi ... View more
