Traffic shaping question

Hi,

I am design a traffic shaping to apply into our network, but I am not sure is it correct or not as Packet Tracer did not support traffic-shape command.

Here is my setup summary:

Internal Network: 10.235.132.0/24

facing interface: FastEthernet 0/0

- Limit outgoing bandwith to following dest 5Mbps
Dest address:  20.181.0.0 0.0.255.255
Dest address:  20.182.0.0 0.0.255.255

- Limit outgoing bandwidth to following dest 10Mbps
Dest address:  30.188.0.0 0.0.255.255
Dest address:  30.189.0.0 0.0.255.255

- Others local is unlimited bandwidth

- Did not limit the incoming traffic to 10.235.132.0/24 even reach to max bandwith limit with destination port 8080

WAN interface: fastEthernet 0/1

My setup

Access-list

access-list 110 permit ip 10.235.132.0 0.0.0.255 20.181.0.0 0.0.255.255
access-list 110 permit ip 10.235.132.0 0.0.0.255 20.182.0.0 0.0.255.255

access-list 111 permit ip 10.235.132.0 0.0.0.255 30.188.0.0 0.0.255.255
access-list 111 permit ip 10.235.132.0 0.0.0.255 30.189.0.0 0.0.255.255

(how to set other location is unlimited bandwidth?)

interface FastEthernet 0/0
traffic-shape group 110 5000000
traffic-shape group 111 10000000
end

access-list 120 permit ip any 10.235.132.0 0.0.0.255 eq 8080
interface FastEthernet 0/1

(no idea how to apply it)

Did any body can help me to check and advise if I am wrong and I did not understand is it need to apply in/out for each interface?

Thx!

Hi Machi,

You should use class based traffic shaping. This gives you option to apply CBWFQ inside shaper, and it is cisco recommended mechanism to do shaping. For the inbound direction, there is no queueing mechanism.

If you want stay with your GTS, the shaping should be applied of the outbound direction on fastEthernet 0/1.
