QoS - Bandwidth management

[jojiv]

Hi All,

I am planning to deploy QoS across my WAN for bandwidth management. I have 4 type of classes including the default class. Class A should have 35 %, Class B have 25%, Class C should have 15% and class default should have 25% of bandwidth at the time of congestion. If there is no congestion, the free bandwidth should devide among the 4 classes.

One more requirement is that Class C shloud use more bandwidth only when the other classess are not utlilzing the free bandwidth. If Class A or CLass B or default class requires free bandwidth , the bandwidth of Class C should restrict to 15%. CLass C can use the free bandwidth only when the other classes are not utilizing the free bandwidth

How can I achieve he above requirement, I prefer to use bandwidth command

Regards

JMV

Hi,

If you want more than 75% for all your classes then you'll have to configure for the interface:  max-reserved-bandwidth 100 in your case as you want 100%

But that is not really recommended to do so.

If Class A or CLass B or default class requires free bandwidth , the bandwidth of Class C should restrict to 15%

then you should police to restrict to 15% but you can't do conditional policing as far as I know

CLass C can use the free bandwidth only when the other classes are not utilizing the free bandwidth

CLass C will use the free bandwidth when the other classes are not utilizing the free bandwidth but again can't condition this.

Regards.
