I have a 100M Internet circuit connecting to a Cisco ISR4331 router. We are planning to upgrade the circuit to 400M, and have multiple businesses use this circuit.
Can I implement traffic shaping to limit certain businesses to use only 300M of bandwdith, and have the remaining 100M for the other businesses. If yes, how do I differentiate the source traffic between these businesses while implementing traffic shaping?
if the business units can be classified based on IP address subnet you can use access lists to create class-maps and then you can use hierarchical QoS with a parent shaper and child policies.
If this is not possible you need to use NBAR (match protocol) and classify traffic at application layer.
Hope to help
Thanks for your reply. Yes, the business units are classified into different subnets.
Could you please help me with any configuration examples, or guide me to any webpage for reference.
very good point about possible performance issues with increased aggregated traffic.
>> Also BTW, you realize an ISR 4331, to support 400 Mbps, especially duplex, will need a boost license, and even then, it might not be able to constantly guarantee above 300 Mbps aggregate performance?
