SRR or WRR on Catalyst

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:

http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cg/hqos_c/index.htm

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.
