Cisco 3750 Traffic Shaping

Nicholas Beard
Level 1
Level 1

Hi all,

I am looking to obtain some information regarding traffic shaping on a Cisco 3750v2 fast ethernet switch stack.  I have 8 customers which will shortly be connected via access switch uplinks to a 3750v2 switch stack.  Each customer will be segregated into VLANs and uplinked to the 3750 and use either a Layer 3 SVI on the 3750 or a routed port to route out to the internet.  I have two (active/standby) internet feeds presented to the 3750 stack running at 100mb.  What i need to be able to do is traffic shape to the internet feed to split it into either 10mb or 20mb feeds; one feed per customer.

Would it be most appropriate/efficient to traffic shape on egress (rather than traffic police) the SVI or routed port of each customer?  I could then use aggregate rate shaping feature that specifies the maximum combined trnasmission rate of all four queues on the port.  For example, if SVI VLAN 2 was for customer 2 and could transmit no more than 10mb, then all four queues on that SVI cannot exceed 10mb.  At this point in time there is no requirement to classify traffic passing through the port, therefore, the only complexity is to limit each customer port to no more than 10mb or 20mb.

If anybody could provide maybe a configuration example, or a better method to achieve this that would be greatly appreciated.

Regards

Nick

Nick,

I think you  have the right approach for this. I have used medianet campus design guide in the past to test some of the QOS policies on different platforms. This should help with your planning.
