Faq (CISCO2951/K9)

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?

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.

CISCO2951-V/K9, the CME will be activated on the device CISCO2951-V/K9?

YES, buying a FL-CME-SRST-25 license (25 seat license).

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.

What is the exact HSEC-k9 license?

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.

What countries are classified license-free zones?

Countries belonging to the EU license-free zone include Australia, Austria, Belgium, Bulgaria, Canada, Cypress, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Latvia, Lithuania, Luxembourg, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, United Kingdom, and the United States.

Are there any restrictions with the memory modules for the new platforms?

The Cisco 2900 Series Integrated Services Routers ship with higher default memory (both DRAM and Compact Flash) than today's integrated services routers. The Cisco 2951, 3925, 3925E, 3945, and 3945E routers have two modular dual-inline-memory-module (DIMM) slots for error-correcting code (ECC) double-data-rate 2 (DDR2) synchronous dynamic random access memory (SDRAM)-each slot capable of integrating 512 MB to 2 GB DIMM.

What is an enhanced high-speed WAN interface card (EHWIC)?

The EHWIC is an updated and enhanced version of the HWIC already available with existing integrated services routers. It offers greater speeds and higher port density than the current HWIC. EHWIC slots can support modules that provide both product-based Cisco Inline Power and PoE. EHWICs are available in two form factors: a singlewide form factor that takes up 1 slot and a doublewide form factor that takes up 2 slots. Note: You can combine two EHWIC slots into one bigger slot (EHWIC-D) by removing the center rail between two individual slots. The EHWIC slot is also backward-compatible with existing HWICs, voice interface cards (VICs), and WICs.

What is an internal service module (ISM)?

The ISM is the evolution of the AIM slot available on earlier integrated services routers. It provides additional capabilities such as increased throughput and integration with the MGF in the integrated services routers generation 2. Note that existing AIMs will not work in the new ISM slot.

What module will replace the Cisco AIM-VPN Module?

There is currently no plan for any VPN acceleration ISM module. The integrated services routers generation 2 include built-in hardware acceleration for encrypted traffic, and in effect they already include AIM-VPN functions as part of the default platform hardware.

Can I reuse my existing PVDM2 DSP modules in the Cisco 2900 Series routers?

Yes. You can install PVDM2s on the motherboard PVDM slots using the PVDM adaptor cards (PVDM2-ADPTR). You can also insert the high-density voice network modules (NM-HDV2s) with PVDM2s into the service-module slots of the Cisco 2900 and 3900 Series routers by using the network module-to-service module adapter card (SM-NM-ADAPTR).

cisco 2951 router has one SFP slot but I don't know if this order will supply the sfp module or not. So I also bought a glc-sx-mm. Both of the items work well.
