    I'm working on a qos config for a cisco. The scenario is as follows:

    We provide a 100Mb service into a premises.
    Several IP networks are routed to the premises.
    We'd like to allocate 90% of the bandwidth to /24 & the remainder to the following network -

    I have the following config so far, which is limiting the network to about 90% and also applying the limit to the network, but it doesn't appear that the network can utilize the 'spare' bandwidth when it isn't being used by

    Can anyone offer some suggestions or better ways to achieve the same outcome?
    btw the below config is being applied to the customer's upstream router on a sub-interface (our router) :)

    class-map match-any customer-1
    match access-group 100
    class-map match-all data
    match access-group 150

    policy-map bw-reserve
    class customer-1
    priority percent 90
    class data
    priority percent 10

    policy-map qos-voip-parent
    class class-default
    shape average 20000000
    service-policy bw-reserve

    interface FastEthernet0/0.10

    Thanks in advance,
