Hi
If I have the following policy applied on an output WAN e1 interface would the router know that wred should only drop random drop when the actual e1 is congested, so for example if AF1x is using 784k and all other classes are free, will the router allow it to burst or will it random drop once it starts bursting over 512 due to class bandwidth.
Interface Serial x/x:0
bandwidth 2048
Policy Map OUTPUT-WAN
Class All-AF2x
bandwidth 1024
random-detect dscp-based
Class All-AF2x
bandwidth 512
random-detect dscp-based
Class All-other
bandwidth 512
random-detect dscp-based
thanks

Your class based WREDs will only "activate" if packets queue within that class.
The class bandwidth sets a minimum guarantee, i.e. they, alone, don't preclude additional bandwidth being used.
If AF1x was using 784k, and no other classes were active, then there would be no congestion and no WRED activation.
