Hi folks,
while talking of shaping outgoing traffic with a network architect I was told that limiting it, for instance to the 80% of the declared bandwidth of an interface (it might be a tunnel), is not only advantageous because we limit the packet drops (with regard to this the longer the queue the better) but also because we make space for management traffic.
Just to give an idea the policy should be defined in this way
policy-map GRE_OUT class class-default queue-limit 512 packets ! policy-map Shape_GRE_OUT class class-default shape average 80000000 account user-defined 24 service-policy GRE_OUT
I was not completely convinced but then I tried to find an explanation for myself and I wonder if shaping is only applied to traffic that is forwarded by a router and doesn't apply to self-originated traffic. Of course forwarded packets and self-originated ones then do compete to get out of an interface.
May anybody validate my reasoning, am I wrong? Am I right? And why?
Sorry for such a basic question but I could not find a clear answer on the web or on the community.
Thanks,
Alex
