I have configured QoS, on a 6509. Whilst doing some testing (ftp transfers
between client and server), by applying the different ACL's, there is an
apparent throttling type action, but we cannot see any indication of dropped
packets, but there are retries displayed on the ftp server. Any suggestions
on what can be entered to monitor this, or anybody have any suggestions for
software that can be installed on a Win98 laptop, to be used to monitor
Cisco networks, whilst at different customer sites? Below is the config
used, and the output from a 'show qos stat <port>' command
#qos

ACL acl128 is successfully mapped to port 3/5.
The old ACL mapping is replaced by the new one.
