Hi Michael,
-> Won't max-reserved-bandwidth 100 be a good default command to use with
MQC interfaces?
Reserving 100% of the total bandwidth may starve the router generated
traffic and break routing protocols and other essential management traffic.
That's why it is 75% by default and not 100%.
Cheers,
Ato.

Well, if you are using more that 75% of the bandwidth value (per the show
int cmd) then you need to up the upper limit.
R8(config-if)#max-reserved-bandwidth 100
Which brings up a question,
Won't max-reserved-bandwidth 100 be a good default command to use with MQC
interfaces?

Thank you Ato.
My question was more in regards of whether or not you have to specify the
command when reserving bandwidth. I've seen MQC configurations with and
without the interface level bandwidth command. I think your saying that I
only need to specify bandwidth if the reference bandwidth is different than
the interface bandwidth.
Thanks

Hi Alsontra,
Both bandwidth commands have very different meanings.
Under the interface, it means the total reference bandwidth. Used for QoS
but also for routing protocols, etc... Normally you need to change it in
serial interfaces where the real bandwidth is different from T1, etc...
Under the class in a policy map, it is the bandwidth you want to reserve for
a particular class. The total reserved bandwidth cannot exceed by default
75% of the reference bandwidth.
Cheers,
Ato.

When is the interface level bandwidth command used or needed with MQC?
For example:
class-map match-all ICMP
match access-group 101
policy-map ICMP_BW
class ICMP
bandwidth 128
interface fa1/0/0
bandwidth 1500 <-----------------------------When does this need to be
specified?
service-policy output ICMP_BW
If I don't specify this, what value dose the interface policy use? The
interface bandwidth rate? And if so why would I want to change it?
