bandwidth percent - ios xr

hi everyone, in a policy map - when you configure your classes - ex class 1 bandwidth percent 25 class 2 bandwidth percent 25 class 3 bandwidth percent 25 class 4 bandwidth percent 25 - will this negate p2mdrr or mddr? ie. have I configured the policy to "not" have any remaining available bandwidth to any other classes? thanks, Andrew

hi andrew,bw percent gives

hi andrew,

bw percent gives you a defined assigned CIR based on the parent shaping bandwidth.

bandwidth remaining (percent) will get a modified deficted  rate of the left over bandwidth after all the classes have been served that have an assigned CIR.

you can see how the programming of the shaped classes has been done with the command show qos int <interface> <direction> which gives you the CIR that is currently running on that class and their (excess) weight ratio as determined by the scheduler, available bw and all that.

cheers
