[c-nsp] Qos between CE and PE

[Dirk-Jan van Helmond]

remember that the priority command POLICES to a bitrate, not shapes.

When you police a TCP session, things start to go terribly wrong with CA
windows etc.

So shape the traffic before you police it.

regards,
Dirk-Jan

ps. why are you prioritizing FTP traffic?
pps. if you are going to allocate more than 75% of the bandwidth to a
class, remember to up your max-reserved-bandwidth to 100% (or some other
value, higher than the acculumated assigned bandwidth for all classes).
