the Integrated Services Routers Generation 2 platforms are supported on Cisco 
IOS Software releases 15M&T. Release 15.0(1)M is available immediately and 

provides support for a comprehensive portfolio of Cisco technologies, including 
the functionality and features delivered in releases 12.4 and 12.4T. New 
innovations in 15.0(1)M span multiple technology areas, including security, 

voice, high availability, IP Routing and Multicast, quality of service (QoS), 
IP Mobility, Multiprotocol Label Switching (MPLS), VPNs, and embedded management.

Cisco IOS Software Licensing and Packaging

A single Cisco IOS Universal image encompassing all IOS technology feature sets 
is delivered with the platforms. You can enable advanced features by activating 
a software license on the Universal image. In previous generations of access 

routers, these feature sets required you to download a new software image. 

Technology packages and feature licenses, enabled through the Cisco software 
licensing infrastructure, simplify software delivery and decrease the 
operational costs of deploying new features.

Four major technology licenses are available on the Cisco 2900 Series Integrated 
Services Routers; you can activate the licenses through the Cisco software. 

Thefour licenses are as follows:

● IP Base: This technology package is available as default.

● Data

● Unified Communications

● Security (SEC) or Security with No Payload Encryption (SEC-NPE)

The Cisco license provide greater flexibility to deploy new features while also 
improving visibility and management of existing licenses in the network. 
The Cisco ISR 1900, 2900 and 3900 Series adopt the Universal IOS image model 

enabling customers to future proof their networks. Cisco 3925E and Cisco

Cisco Router Throughput

Let’s know about the Cisco router throughput from the below message:

1 No Drop Rate and RFC-2544 Tests

Routers have traditionally been tested using RFC 2544 or similar types of performance tests. RFC 2544 requires tests to be run at a no drop rate (NDR). This testing is done by using a fixed packet size, usually 64-byte packets, and the results are usually published as a metric in kilopackets per second (kpps). The tests are designed to show the CPU power and processing power of the platform (Table 1).

Another popular technique for providing router performance information is also an NDR test, but it is performed with maximum packet size and presented as a throughput test. Results are delivered as megabits per second (Mbps).

This test yields a maximum data-rate forwarding of specific features.

For NDR tests sometimes the platforms can process and forward packets faster than the aggregate bandwidth of the interfaces that the specific models can support. In this situation, all available interfaces are driven to line rate and CPU usage recorded.

What these tests do not provide is any indication of how the router will perform in a production environment. They assume that router CPUs scale linearly to the point where they drop packets. The tests provide no means for analyzing router services, software-based algorithms, or other features. There is no ability to account for real protocols, application layer gateways (ALGs), or other real-world traffic.

Also, production networks tend to have varied packet sizes. Voice traffic and TCP acknowledgements (ACKs) tend to be very small packets, generally 64 to 80 bytes. File transfers and some applications tend to use as large a packet size as they can negotiate. Thus, NDR tests with fixed packet sizes do not provide a very realistic look at router performance in a production environment.

2 Firewall testing

Firewall testing is much more complicated than any other test discussed in this document. Zone-based firewall (ZBF) is a stateful application, maintaining and monitoring the state of all TCP connections through it. It has multiple ALGs that allow it to inspect and monitor specific protocols and applications. ZBF also inspects traffic both within and between zones.

Thus, test methodology significantly affects performance. Testing different applications invokes specific ALGs, each of which may affect test results differently. Many test tools can generate packets with TCP headers, but never complete the handshake and establish state for monitoring. In some situations, the firewall may see this situation as a denial-of-service (DoS) attack, because it would rarely be encountered in a production network unless under attack. The use of pure User Datagram Protocol (UDP) or other stateless traffic patterns can also produce varying results.

For the purposes of this document, firewall is configured with two zones, and all traffic is sent between zones. The traffic generated is stateless and uses the same UDP port number. Performance is measured in maximum throughput and the number of maximum concurrent sessions. One element that influences the maximum-sessions metric is the

amount of installed memory in the platforms. These tests used default memory. Table 4 gives firewall performance information by platform.

Again, the data presented in this section is for maximum performance and is not very valuable for use in a production network. Although a router may be able to forward more than 1 Gbps of encrypted traffic in a lab-based performance test, it should not be expected to perform at that level in a customer’s network. Packet sizes will vary in a real

network, and routers cannot be stressed to NDR.

Maximum tunnels are a specific point where performance derived in a lab situation varies from a production design.

Although this number is easy to reproduce in a test environment, very little traffic will be forwarded over those tunnels during the test.

Firewall performance will vary depending on the nature of the traffic. Because ZBF monitors the state of traffic and monitors specific protocols and applications, actual application traffic will affect the throughput of the firewall.
