I'm using ATM UBR, so no way to use traditional QOS, as UBR has 0 bandwidth regardless of the actual size of the PVC.
Rate-limit works fine, but I would like to add a time-range to it, so that, for example, WSUS gets only a small slice of bandwidth during business hours, but has full access after hours.
Any help would be greatly appreciated.
Hi, in the router, there is no thing such "true xBR".
The only thing that differentiates traffic management in a router, is the transmit priority of a VC, that have defaults according to the class of service, or you can set your own.
Of course, VBR still obeys the traffic paramenters, and the sophisticated but little used ABR, the feedback machanism.
All other classes, UBR, UBR+ and CBR, are substantially the same thing for a transmitting router.
See the white paper that I wrote when I was with Cisco:
Consequently, as long you find a configuration n that allows you the wanted MQC, doesn't matter for example if one side has CBR (or UBR), and the other has VBR-rt or VBR-nrt with PCR=SCR.
Hope all that makes sense :)
Yes, use time-based ACL. I suggest you do traffic-shaping rather than rate limiting.
