Max Throughput ISR 4331 Booster Lic can handle

Lapta
Beginner
Beginner

Hello Folks,

 

From ISR 4K Series Data Sheet  ISR 4331 with boost license's throughput is over 2Gbps. 

4431 boost lic throughput is over 4Gbps.

Well, 4331 should not able to hit 4Gbps, right? So what is "OVER 2Gbps" ?

I can not find in any other cisco documentation about the fix maximum limit for 4331 throughput.

How about 2.5Gbps aggregate traffic acrose all of the egress traffic? can 4331 handle it?

A boost license removes the license performance cap, so you can obtain whatever performance the router can provide running at 100% CPU.  What can be achieved at full 100% CPU load very much depends on your configuration and your traffic.

I've attached an earlier Cisco whitepaper on pre-4K ISRs performance.  What to take note of, is how much CPU loading, and maximum throughput, varies, based on router config and traffic mix.  When you uncap/boost a 4K, you'll likely see similar relative results.

So, the "over 2Gbps" likely means simple forwarding of max MTU Ethernet frames.  (Take note of performance numbers in Table 1, where even a 1921 can have "over 2Gbps" throughput.)

You might also want to view https://miercom.com/pdf/reports/20150817.pdf stats on the 4331, page 12, and look at percent of CPU loading for various configurations.  I.e. @300 Mbps, lots of unused CPU capacity for just IPv4 forwarding, but CPU pretty much fully utilized for FW, NAT, QoS and IPSec.

If this is still unclear, let me know.

Max 1GB for that model  if you looking 2.5G then you need to uplift the model to 4461

You right Joseph. Thanks for help clearing this over throughput.

 

I found CPU load test with boost license. On aggregate CEF, 4331 can handle 2Gbps with 53% CPU and will increase along with configured feature like netflow, ipsec, etc.
