I have a 2811 router connected via one of it's FastEthernet ports to a managed Cisco router which provides Internet access for us.
I would like to use QOS to give traffic to certain key websites priority over other traffic. I am familiar with QOS over serial connections, and those work great. But yesterday a group of our students all launched BitTorrent and World of Warcraft, and completely saturated our 3Mb/sec of Internet bandwidth the entire day. I would have expected our important traffic to be given more bandwidth and less likely to be dropped, but even at it's worst, the queueing did not seem to work.
Can anyone help?
set dscp af21
bandwidth remaining percent 75
set dscp default
bandwidth remaining percent 25
class-map match-any class_toMerit
match access-group name ACL_dest_merit
service-policy output pmap_Merit_Out
During the height of the bandwidth problems this is what a "show queue" displayed; which is not at all what I would expect from a totally saturated link:
#show queue fastethernet0/0
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: Class-based queueing
Output queue: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/2/256 (active/max active/max total)
Reserved Conversations 2/2 (allocated/max allocated)
Available Bandwidth 2304 kilobits/sec
