What is the Aggregate Throughput for ISR C1111-8P Router

[Asifkhan86]

Hi,

The performance positioning as per Cisco site is 350Mbps but somewhere the Data sheet its mentioned that the Encryption data is limited to 50Mbps by default and needs performance licence to increase the same to 250Mbps.

https://www.cisco.com/c/en/us/products/routers/1000-series-integrated-services-routers-isr/compare-model.html

Does this mean that if we are not using IPsec, we can use the full 350Mbps and only if we are using IPsec then we need the licence if the bandwidth requirement is more than 50Mbps.

Thanks & Regards,

Yes. (BTW, I believe the higher IPSec bandwidth license also requires you not be in a country limited encryption performance.)

Could you please help to advise for number of concurrent users access ? 

the use cases, is currently to enable 250Mbps with SD-WAN configuration, number of access users is 200+, cloud application with Microsoft meeting.

Sure, take the average bandwidth consumption and the sum of combined number of users should not exceed about two thirds of the router's forwarding capacity nor about one third of WAN bandwidth.  (If QoS is used, something like Microsoft meeting will like need being able to obtain abot 3x its average bandwidth consumption but actual unused bandwidth can be used for other purposes; presuming QoS can preempt it.)

Forgoing is rough estimating, but will likely be in the ballpark to insure acceptable performance.
