Cisco Maintenance
Maintenance Solutions That Put You In The Driver’s Seat
With Cisco being the popular choice for network hardware among IT professionals for several years, the maintenance solution has traditionally been to go with the OEM options.
However, you do have very good choices outside of Cisco SmartNet for your Cisco switches and other hardware. In fact, CXtec has right-sized maintenance solutions for your Cisco gear based on your specific goals and criteria.
Right-sized Maintenance Solutions
With our own brand of hardware maintenance, RapidCare®, we help IT professionals optimize their maintenance while reducing costs.
Based on your hardware refresh cycle, goals, and other business factors our team can craft a solution that works for your specific needs.
From our experience, for most companies the best option is adopting a hybrid maintenance solution that combines Smart Net with an independent service such as RapidCare maintenance.
RapidCare® Hardware Replacement Services
When you buy used Cisco equipment for sale from CXtec, you also have the added option of protecting your important investment with maintenance offering that allows you to optimize and customize your hardware support while reducing costs.
RapidCare®, the ultimate next-business-day replacement service that provides you with maximum uptime at 50% or more off traditional OEM maintenance service.
Hybrid Support Strategy is Ideal for Cisco Users
With a hybrid support strategy, you get the best of both worlds. You get to combine the OEM support you’ve grown accustomed to with third-party support options that provide you a whole new degree of flexibility and independence.
You are no longer limited to a single maintenance offering that focuses on supporting newer hardware and diminishes in support and value over time. Learn more about the benefits of hybrid support strategy and how you can reap these benefits yourself.

- —Francis Bacon
After the introductory lessons of the first two chapters, it is time to begin the practical work with the Cisco Classic Network Firewalls. This chapter focuses on topics such as IP address assignment, Command Line Interface (CLI) usage and how to prepare the devices to be remotely managed using protocols such as Telnet, Secure Shell (SSH) and HTTPS.
The contents presented are simple, so if you are already familiar with Cisco Classic Firewalls, you can skip this chapter altogether. If you are just beginning, this chapter's topics are relevant and helpful.
Device Access Using the CLI
Even when planning to manage a Cisco Firewall using a Graphical User Interface (GUI), you probably need to take some initial configuration steps via the CLI. The good news, in this case, is that intelligible and intuitive CLIs have always been a recognized asset of Cisco devices. The CLI is typically accessible through a serial console port or by means of terminal access protocols such as Telnet and SSH. In either situation, a terminal emulation program such as TeraTerm, Putty, or HyperTerminal is necessary.
Throughout the book, unless otherwise stated, CLI access is always assumed.
