QoS on Cisco router

Do you actually have a problem or is it a perceived problem? Does QOS not throttle when other demand increases?

David raises a good point.  Throttle them if there's no spare bandwidth, yes.  But if there is available bandwidth on the network, assuming that you're not paying per megabyte, why should these systems not have it even if they are bandwidth hogs?

imo, it would be prudent to first investigate the nature of the traffic between these systems.  Then get the support of management to help legitimize any action taken.  If somebody's watching Netflix on company time via an unapproved VPN then yes, stomp on them hard.  But throttling critical transactions could have undesirable consequences.  And it might just turn out there is something poorly configured or doing unnecessary updates across that particular link, and correcting it will solve the problem.

Hi David/Klahn,

The traffic between the source and destination is a file transfer traffic.
QoS I believe comes into picture in cases of congestion.
The amount of transfers is huge over the WAN media and its the managements decision to ensure that only a certain max bandwidth be at any point of time i.e. even when there is no congestion file transfer should happen at max 'X' bandwidth and if it goes above that applied the necessary actions.

I was dong my own research where we found that class-maps could be created matching the source and destination after which we could police or shape the traffic.


What would you guys recommend and so send me a sample configuration to match the requirement?

Hi there,
