Cisco ASR Throughput – Cisco ASR1001 License Throughput Measurement

ciscocisco-asrthroughput

Cisco ASR1001 comes with 2.5G throughput license and later you can upgrade to 20G. I have question if i have 10G link and i get attack of 5G and i use ACL to drop all packet on ingress interface in that case does 2.5G comes in picture? How does 2.5G throughput affect my requirement to drop all packet in Ingress.

Best Answer

Yes those dropped packets would factor into available throughput, and this is because ACLs are processed by the ESP [Embedded Services Processor] which measures bandwidth. All those packets are being processed by the ESP.

Anything beyond the licensed throughput during that point in time will not be processed. This includes both good and malicious traffic.

More information on where the various components are handled on the ASR can be found in the following document:http://www.cisco.com/c/en/us/products/collateral/routers/asr-1000-series-aggregation-services-routers/qa_c67-452124.html

On the external interface of your router, use this ACL:

access-list extended NO_FRAG
deny ip any any fragments
permit ip any any
end

interface <ext interface>
ip access-group NO_FRAG in

Throughput Bottleneck – Does Direction Matter?

If a network has a throughput bottleneck, does it matter whether the slow link comes before or after?

No it doesn't, Only matters when destination is before or after that bottleneck link.

What throughput speed will the red arrow have? 200 or 100?

Yes it will be bottle necked at 100mbps. So bottleneck throughput speed would be of the lowest throughput link between h and c. So this bottleneck throughput will be applicable when the packet is sent from h to c also.

Hope this helps!
