More Specification for Services Router

The CISCO3945/K9 is a Cisco 3900 Series Integrated Services Router that provides advanced routing, security, and wireless services in a single, modular form factor. It has 3 integrated 10/100/1000 Ethernet ports and supports a wide range of interface modules to provide connectivity options for different types of networks and services.

Some of the key specifications of this product include:

  • CPU: Dual-core 1.5 GHz
  • Memory: 4 GB DRAM, 4 GB Flash
  • Throughput: Up to 1 Gbps
  • Number of VPN Tunnels: Up to 25,000
  • Number of Sessions: Up to 2 million
  • Power Supply: AC or DC, internal or external
  • Form Factor: 19-inch rack-mountable
  • IOS Software: Cisco IOS XE Software

This model supports a wide range of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP). It also supports advanced security features such as Cisco Identity Services Engine (ISE), Cisco TrustSec, and Cisco Firepower services, which provide enhanced security and threat protection.

Additionally, this product supports Cisco's proprietary Application Visibility and Control (AVC), which allows for detailed monitoring and analysis of application traffic, and Cisco's proprietary Quality of Service (QoS) feature set, which allows for prioritizing network traffic based on different criteria such as IP address, protocol, or port number.

All these features and specifications make this product an ideal choice for building and maintaining a secure, high-performance and reliable network infrastructure, especially for enterprise and service provider environments that require advanced routing, security, and wireless services.

Quality Components

The CISCO3945/K9 is a model of Cisco's 3900 series router that is built with high-quality components to ensure reliable and efficient performance. The router is equipped with powerful processors and large amounts of memory, which allow it to handle large-scale network deployments and support advanced technologies such as Quality of Service (QoS), IPv6, and security features like firewall and VPN capabilities.

The router also has 3 integrated service module ports that can be used to add additional functionality to the router, such as a VPN module or a wireless LAN controller. These ports are designed to support a wide range of modules, allowing the router to be tailored to specific network requirements. The router also has a modular design that allows for easy maintenance and upgrades.

Additionally, this model is built with energy-efficient components and features that help to reduce power consumption and lower operating costs. It also includes an easy-to-use web interface for monitoring and managing the router, making it simple for network administrators to keep the router running smoothly.

Resiliency and High Availability

The CISCO3945/K9 Cisco 3900 Series 3 Ports Integrated Services Module Router is designed with resiliency and high availability features to ensure that network operations are not interrupted in case of a failure or outage.

One of the key resiliency features of this part is its support for redundant power supplies. This allows the router to continue operating even if one of the power supplies fails. Additionally, the router supports redundant fans, which help to keep the internal temperature at safe levels and prevent overheating.

Another important feature for high availability is its support for dual routing engines. This means that the router has two separate processors, each running its own copy of the routing software. In the event that one processor fails, the other one takes over and keeps the network running without interruption. This feature is particularly useful for networks that require 24/7 availability.

This product also supports various redundancy protocols like HSRP, VRRP, and GLBP, which allow for multiple routers to work together to provide redundancy in case of a failure.
