The SEC-K9 permanent licenses apply to the Cisco 1900, 2900, and 3900 ISR G2 platforms; these licenses limit

all encrypted tunnel counts to 225 tunnels maximum for IP Security (IPsec), Secure Sockets Layer VPN (SSL

VPN), a secure time-division multiplexing (TDM) gateway, and secure Cisco Unified Border Element (CUBE) and

1000 tunnels for Transport Layer Security (TLS) sessions.

The SEC-K9 license limits encrypted throughput to less than or equal to 85-Mbps unidirectional traffic in or out of

the ISR G2 router, with a bidirectional total of 170 Mbps. This requirement applies for the Cisco 1900, 2900, and

3900 ISR G2 platforms.

Hi Marcus,

By default it is 8 Mbps with k9 bundle.
If you enable datak9 license on that then you can configure the throughput based on your original WAN link capacity.

In my case, recently I have experienced that in my 1921 router at one site, the original link capacity is 10 Mbps but the throughput under the tunnel is just 8 Mbps.
After I enabled the datak9 license I was able to define the throughput under the tunnel to 10 Mbps.

Please rate the helpfull posts.
