Hi everyone,


I want to do the following QoS configuration. I am having a total bandwidth of 30 Mbps.


I want to have strict priority for voice traffic with guaranteed bandwidth of 5 mb.


15 mb for SMTP traffic.


8 mb traffic need to policed so that excess traffic need to be dropped.


All other traffic should be having default priority.


What policy should I configure SRR or WRR ?


Can anyone give the configuration , also mentioning what and how the values are derived?


Any help will be highly appreciated.


Thanks,

Pete

QoS configuration on 4500 can be found here:

http://www.cisco.com/en/US/docs/switches/lan/catalyst4500/12.2/25sg/configuration/guide/qos.html


General QoS information on IOS can be found here:

Have a read on those documents. Understand them. Play around in the Lab.


Based on your requirements, it sounds like you are looking for a nested MQC approach.
