Over the past week or so I have been going over FRTS for my CCIE studies.
It’s something that I have covered before when studying for my QoS exam and skimmed over when studying for my ROUTE exam but up until now it has never actually stuck.
As others on Twitter have suggested maybe it’s because FRTS is an old technology and not really used anymore, that may be the case but I still remember all the intricacies of frame-relay and those have no problem staying in.
In this post I just thought I would go over the basics of FRTS, how to implement it and the various show commands to help you along the way.
There are several methods of applying FRTS, there is:
FRTS in map-class using the traffic-rate command
FRTS in map-class using the frame-relay shaping commands
FRTS in the MQC
When you apply FRTS there are several points to consider, a few of the most important ones are below:
You can only use it on frame relay interfaces (this really goes without saying)
FRTS is applied to each PVC on an interface individually
You cannot use any other queueing methods on the physical interface alongside FRTS
