I followed the examples on that page but I'm not having any luck. As far as I can tell the queue is dropping at least some packets that it should be prioritizing (look for 582 below). First, here is what i have in my config, and below that is the results of "show policy-map interface". As a side question, the file copy now seems to work much differently in that it does a big "burst" at the start of the copy and then "stalls". Is this a burst while the packet queue fills up? --- config --- class-map match-all cm-qos1 match access-group name al-qos1 policy-map parent_shaping class class-default shape average 128000 service-policy child_queueing policy-map child_queueing class cm-qos1 priority percent 70 interface FastEthernet4 service-policy output parent_shaping ip access-list extended al-qos1 permit ip host xxx.xxx.xxx.xxx any permit ip any host xxx.xxx.xxx.xxx ----========----- l#show policy-map interface FastEthernet4 Service-policy output: parent_shaping Class-map: class-default (match-any) 157430 packets, 69675635 bytes 5 minute offered rate 150000 bps, drop rate 25000 bps Match: any Queueing queue limit 64 packets (queue depth/total drops/no-buffer drops) 47/618/0 (pkts output/bytes output) 15633/18270484 shape (average) cir 128000, bc 512, be 512 target shape rate 128000 Service-policy : child_queueing queue stats for all priority classes: Queueing queue limit 64 packets (queue depth/total drops/no-buffer drops) 0/582/0 (pkts output/bytes output) 3228/2120973 Class-map: cm-qos1 (match-all) 3810 packets, 2978841 bytes 5 minute offered rate 71000 bps, drop rate 25000 bps Match: access-group name al-qos1 Priority: 70% (89 kbps), burst bytes 2200, b/w exceed drops: 582 Class-map: class-default (match-any) 12441 packets, 16201283 bytes 5 minute offered rate 69000 bps, drop rate 0 bps Match: any queue limit 64 packets (queue depth/total drops/no-buffer drops) 46/36/0 (pkts output/bytes output) 12405/16149511 - John Lange http://www.johnlange.ca _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
