Yeah that's what I belive also. This whole thing started with a person
at my work telling me that we should shape a 1984 to 1984 just to
delay packets instead of tail dropping.
I just wanted to get my head around this.
T
> Buffers are not infinite, so you might still see tail drops.
Indeed, but I'm thinking if I only apply the "qos" policy-map, I
switch from fifo to CBWFQ with multiple software queues, and buffers.
If I on top of that do shaping, would I not utilize yet another
buffer? I.E. the shaping buffer.
>
I have a question I have been thinking about.
Let's say we purchased a 5Mbit Ethernet Link. The physical speed of
the link is 10Mbit, so we shape outbound traffic to 5Mbit, like such:
class-map ef
match ip dscp ef
class-map af4
match ip dscp af41, af42, af43
class-map af3
match ip dscp af31, af32

This is the way I did bandwith management on a 3750, policing on

You could try to add a static /32 route to the BADIP on the
