Hello Ahmed,
with the proposed configuration you are just limiting to up to 15 Mbps the traffic that matches the class-map named wireless, that is traffic wth a source IP address matching the ip access-list named wireless.
There is no elastic mechanism with police command to allow use of unused resources.
The C7600 hardware poses limitations on the QoS features supported. I guess that the involved interface gi1/9 is part of an ethernet linecard so it does not support forms of queueing just policing and marking.
You cannot do better then this. In the future if you want to provide more bandwdth to this traffic class you have to change configuration to use a greater rate.
Alternatively you should install SIP+SPA hardware (modules in the C7600 I mean) or other "WAN" oriented linecards with fewer ports per slot but with more QoS features.
Hope to help

Hello Ahmed,
it just provides a BW limitation to 15 Mbps no guarantees strictly speaking
Hope to help

hi ,
this means bad news for 7600 , i began to anger from this 7600 module at all !!!!!!!!!
can i gurantee bw if i applied config to giga interface , or i stop thinking about bw gurantee in 7600 and begin thinking in buying something like 7206 ???
i just need to gurantee bw and hope to be supported .
