Folks
Here is the brief description for what i am trying to do. It will be a great
help if any one can provide some input.
Objective
To test the Class Based WFQ Configuration on the Cisco Router.
I am attaching the the Configuration file for the router.
I am using the two POS interfaces of the router POS4/0/0 and POS5/0/0
Transmitting traffic to POS4/0/0 destined for equipment attached to POS5/0/0.
Two streams of traffic are being generated. One with Precedence set to 5 at data
rate 31 Mbps and second with Precedence set to 0 at data rate
130 Mbps.
Following access-list is configured
access-list 101 permit ip any any dscp cs5
The Class1 is configured for Bandwidth 50 Mbps. and Policy1 which is
implementing class1 is configured on the POS5/0/0
Policy-map matches the access-group 101
Following are the results i get when i run the traffic through the router.
Problem 1.
The command "show access-list 101" gives the output
Extended IP access list 101
permit ip any any dscp cs5 (231272 matches)
Which means the traffic with Precedence 5 is matched by the access-list. So the
access-list is configured properly.
Whereas the command "show policy-map interface pos5/0/0" gives
butthead#sh policy-map interface pos5/0/0
POS5/0/0
output : policy1
Class class1
Weighted Fair Queueing
Output Queue: Conversation 265
Bandwidth 50000 (kbps) Max Threshold 1 (packets)
(pkts matched/bytes matched) 0/0
(pkts discards/bytes discards/tail drops) 0/0/0
Class class-default
Weighted Fair Queueing
Output Queue: Conversation 266
Bandwidth 1000 (kbps) Max Threshold 1 (packets)
(pkts matched/bytes matched) 0/0
(pkts discards/bytes discards/tail drops) 0/0/0
Which means none of the packets are matched by the service-policy.
Problem 2.
Inspite of Class1 configured for 50Mbps and traffic transmitted with
Precedence 5 is 31Mbps i see packet drop for Precedence 5 traffic at the output
of POS5/0/0
Whereas since there is congestion on the POS5/0/0 and policy-map
configured to 50Mbps, i should not see any packet drop for the traffic with
Precedence 5 and only packets with Precedence 0 should be dropped.
I have been trying to figure out for quite a while.
Thanks a lot for your help.
