Dear All,
I'd like to apologize for my mistake in this sentence.
because I used "bandwidth" command, not "bandwidth percent" one.
It should be
because I used "bandwidth percent" command, not "bandwidth remaining
percent" one.
Best Regards,
Wittawat H.

Subject: QoS Shaping Hierarchical Policy Maps issue !!!
To: ccielab@groupstudy.com
Dear All,
Please help me to clarify this configuration that stated below.
policy-map child
class x
bandwidth percent 50
class y
bandwidth percent 20
class z
bandwidth percent 10
policy-map parent
class class-default
shape average 384000
service-policy child
int s0/0
service out parent
In my opinion, I think that traffic that going out of interface serial 0/0
is rate-limited to 384 kbps total. and then
class x should get minimum bandwidth guaranteed to 384 kbps x 0.5,
class y should get minimum bandwidth guaranteed to (384 kbps x 0.5) x 0.2
class z should get minimum bandwidth guaranteed to ((384 kbps x 0.5) x 0.2)
x 0.1
because I used "bandwidth" command, not "bandwidth percent" one.
But, according to "Implementing Cisco Quality of Service" volume 2, version
2.2 study guide, it stated that
class x get minimum bandwidth guaranteed to 384 kbps x 0.5 = 192 kbps
class y get minimum bandwidth guaranteed to 384 kbps x 0.2 = 76.8 kbps
class z get minimum bandwidth guaranteed to 384 kbps x 0.1 = 38.4 kbps
So, these result made me confusing about "bandwidth percent" command
accompany with shaping hierarchical policy map.
Thank you in advance.
Best Regards,
Wittawat H.
