Each IOS Image therefore include a feature set, which determine the command-line interface (CLI) commands and features that are available on different Cisco. The core function of Cisco IOS is to enable data communications between network nodes. In addition to routing and switching, Cisco IOS offers. The Cisco IOS (Internetwork Operating System) is a proprietary operating system that provides routing, switching, and internetworking features.

The CLI uses a hierarchical structure for the modes. To enter commands into the CLI, type or copy-and-paste the entries within one of the several console command modes. Each command mode is indicated with a distinctive prompt. By default, every prompt begins with the device name. Following the name, the remainder of the prompt indicates the mode, As commands are used and modes are changed, the prompt changes to reflect the current context.

Pressing Enter instructs the device to parse and execute the command Cisco IOS Software uses a hierarchy of commands in its command-mode structure. Each command mode supports specific Cisco IOS commands that are related to a type of operation on the device. Save my name, email, and website in this browser for the next time I comment.

IOS is shipped as a unique file that has been compiled for specific Cisco network devices. Each IOS Image therefore include a feature set, which determine the command-line interface CLI commands and features that are available on different Cisco devices. Upgrading to another feature set therefore entails the installation of a new IOS image on the networking device and reloading the IOS operating system. Information about the IOS version and feature-set running on a Cisco device can be obtained with the show version command.

Most Cisco products that run IOS also have one or more "feature sets" or "packages", typically eight packages for Cisco routers and five packages for Cisco network switches. For example, Cisco IOS releases meant for use on Catalyst switches are available as "standard" versions providing only basic IP routing , "enhanced" versions, which provide full IPv4 routing support, and "advanced IP services" versions, which provide the enhanced features as well as IPv6 support.

Routers come with IP Base installed, and additional feature pack licenses can be installed as bolt-on additions to expand the feature set of the device. The available feature packs are:. IOS images can not be updated with software bug fixes. To patch a vulnerability in an IOS, a binary file with the entire operating system needs to be loaded. Cisco IOS is versioned using three numbers and some letters, in the general form a.

Rebuilds — Often a rebuild is compiled to fix a single specific problem or vulnerability for a given IOS version. For example, Rebuilds are produced to either quickly repair a defect, or to satisfy customers who do not want to upgrade to a later major revision because they may be running critical infrastructure on their devices, and hence prefer to minimize change and risk.

Interim releases — Are usually produced on a weekly basis, and form a roll-up of current development effort. The Cisco advisory web site may list more than one possible interim to fix an associated issue the reason for this is unknown to the general public. Maintenance releases — Rigorously tested releases that are made available and include enhancements and bug fixes. Cisco recommend upgrading to Maintenance releases where possible, over Interim and Rebuild releases.

Cisco says, "A train is a vehicle for delivering Cisco software to a specific set of platforms and features. Before Cisco IOS release 15, releases were split into several trains , each containing a different set of features. Trains more or less map onto distinct markets or groups of customers that Cisco targeted. There were other trains from time to time, designed for specific needs — for example, the This train includes both extended maintenance releases and standard maintenance releases.

The M releases are extended maintenance releases, and Cisco will provide bug fixes for 44 months. The T releases are standard maintenance releases, and Cisco will only provide bug fixes for 18 months. Because IOS needs to know the cleartext password for certain uses, e.

This is designed to prevent "shoulder-surfing" attacks when viewing router configurations and is not secure — they are easily decrypted using software called "getpass" available since , or "ios7crypt", [15] a modern variant, although the passwords can be decoded by the router using the "key chain" command and entering the type 7 password as the key, and then issuing a "show key" command; the above example decrypts to "stupidpass". However, a local account is usually still required for emergency situations.

For Cisco products that required very high availability, such as the Cisco CRS-1 , the limitations of a monolithic kernel were not acceptable. In Cisco introduced the Cisco IOS XR network operating system on the series of network routers , extending the microkernel architecture from the CRS-1 routers to Cisco's widely deployed core routers. In Cisco introduced IOS Software Modularity, which extends the microkernel architecture into the IOS environment, while still providing the software upgrade capabilities.
