Q I need for 2 units Cisco2951 for connecting to T3 network. Is these specifications can work: 2 GB RAM, with min IOS 15.0(1)M, NM-1t3/E3 module and 8 ports Gbps RJ-45?
A YES, but you should buy a SM-NM-ADPTR Network Module Adapter for your NM-1t3/E3 module and more, one EHWIC-D-8ESG card to support 8 Gbps RJ-45 port.
Q CISCO2951-V/K9, the CME will be activated on the device CISCO2951-V/K9?
A YES, buying a FL-CME-SRST-25 license (25 seat license).
Q What is the exact HSEC-k9 license?
A The HSEC-K9 license removes the curtailment enforced by the U.S. government export restrictions on the encrypted tunnel count and encrypted throughput. HSEC-K9 is available only on the Cisco 2921, Cisco 2951, Cisco 3925, Cisco 3945, Cisco 3925E, and Cisco 3945E. With the HSEC-K9 license, the ISRG2 router can go over the curtailment limit of 225 tunnels maximum for IP Security (IPsec) and encrypted throughput of 85-Mbps unidirectional traffic in or out of the ISR G2 router, with a bidirectional total of 170 Mbps. The Cisco 1941, 2901, and 2911 already have maximum encryption capacities within export limits.
Q On the Cisco ISR G2 routers with the SEC-K9 license, what tunnel count and performance throughput are available?
A 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.
