CISCO1941-SEC/K9

Can I upgrade my CISCO1941/K9 to this model?

Yes, but you need to buy a Sec license separately.

On the Cisco ISR G2 routers with the SEC-K9 license, what tunnel count and performance throughput are available?

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.

Why do I need to purchase the SEC-K9 license as a spare?

If you purchase a Cisco ISR G2 chassis and later decide to turn on security features, you must buy a SEC-K9 license. The administrator must download the license to the router and follow the license installation instructions that come with the license to be able to use the security features on the router.

If I purchased a Cisco ISR G2 router on Cisco IOS Software Release 15.0(1) M before the limitation was imposed, what should I do? And should I need to upgrade my Cisco IOS Software?
