The Cisco is deciding to stop the ISR G2. Cisco Integrated Services Routers Generation 2 will be end-of-sale and end-of-life in Dec 2017. Yes, the Cisco ISR G2 will be replaced by the more powerful Cisco ISR 4000 Series. Why do the Cisco users migrate to ISR 4000 series? Cisco has already listed the main benefits while migrating to Cisco ISR 4000 Series:
Benefits of Migrating to Cisco 4000 Series Integrated Services Routers
When you need “always on” branch services, please consider the new 4000 Series ISR!
Ideal for small, medium and large branches, the 4000 Series delivers critical branch network services, industry leading security, and multiple levels of redundancy, including Verizon XLTE, for “always on” business continuity.
Fueled by Cisco IOS-XE for up to 2Gbps performance with Advanced Network Services enabled, the 4000 Series provides industry-leading network, security, compute, and storage services to help you meet every day network challenges, and extend new hybrid WAN architectures and cloud services across remote sites.
In addition to industry leading functionality, the 4000 Series offers a new Verizon Wireless 4G XLTE Module, Application Centric Services, and programmability to maximize utility and deployment flexibility.
Enhanced Redundancy w. 4G XLTE NIM
Do you need enhanced business continuity?
Business continuity and increased resiliency are standard in the ISR 4k. Here are a few examples:
- Resilient multi-core CPU architecture using separate control and data services planes.
- Dual integrated power supplies (4451 and 4431 ISRs), and optional power supply for additional PoE power.
- Modular interfaces with online removal and insertion (OIR) for module upgrades without network disruption.
- Modular network interfaces for load-balancing and diverse connection options (T1/E1, T3/E3, Serial, xDSL, Gigabit and Ten-Gigabit Ethernet) for network resiliency.
- For more information on features and capabilities of the ISR 4k family, please review the data sheet here.
Adding to the line of modular Network Interface Modules (NIM) and diverse connection options, the 4000 Series can now be equipped with the Verizon Wireless XLTE NIM to help improve business continuity.
Extensibility for New Services
Is your network in transition?
Meeting application performance expectations has become more complex with the transition to IWAN, cloud, virtualization and bring-your-own-device (BYOD) environments. Traditional challenges with network congestion and latency are amplified.
For example, as more web-based applications are deployed or run over shared infrastructure, visibility for capacity planning and troubleshooting becomes obscured. In addition, bandwidth demanding applications such as virtual desktops and latency-sensitive applications such as video can have poor performance with a centralized deployment model.
Cisco AX delivers application-centric networking by integrating essential application aware services and infrastructure tools into the router, in a pay-as-you-grow model enabling you to overcome these challenges.
Another option to gain needed service extensibility is to purchase Cisco One Software with your ISR 4000 routers. Cisco One features “better together” pricing, reduced complexity, simplified buying and the peace of mind that today’s software investments can be utilized on hardware platforms purchased in the future.
Cisco One software offers expense predictability throughout the lifecycle of the underlying hardware.
Deploying and managing new applications with the ISR 4k API
Are you prepared for the unknown?
Do you know all the services your users and network will demand in the future? Most don’t. For needed extensibility to support today’s services, and for services you may not even know you will need, the 4000 Series offers Cisco IOS Embedded Event Manager (EEM).
EEM is a unique subsystem within Cisco IOS Software that allows customers to harness the significant intelligence within Cisco IOS Software to respond to real-time events, automate tasks, create customized commands, and take local automated action based on conditions detected by the Cisco IOS Software.
Custom programs or scripts, referred to as EEM policies, can be programmed using a simple Command-Line-Interface (CLI)-based interface or using a scripting language called Tool Command Language (Tcl).
Specific to ISR LTE services, several scripts already exist to support ease of provisioning, and platform and mobile management.
With EEM you take even more control of your environment to customize your user experience, ease your administration and to be prepared for new service demands.
The Cisco ISR 4000 family has 6 members now. They are ISR 4221(the newest one), 4321, 4331, 4351, 4431 and 4451 router.
What are the differences among the six models? Cisco also updated the newest model comparison of ISR 4000 series. Let’s take a look.
