Through the CLI, the commands available to each privilege level can be defined. Most builds of IOS include a Tcl interpreter. Using the embedded event manager feature, the interpreter can be scripted to react to events within the networking environment, such as interface failure or periodic timers.

Available command modes include: [6]. Cisco IOS has a monolithic architecture, owing to the limited hardware resources of routers and switches in the s. This means that all processes have direct hardware access to conserve CPU processing time.

There is no memory protection between processes and IOS has a run to completion scheduler , which means that the kernel does not pre-empt a running process. Instead the process must make a kernel call before other processes get a chance to run. IOS considers each process a single thread and assigns it a priority value, so that high priority processes are executed on the CPU before queued low priority processes, but high priority processes cannot interrupt running low priority processes.

The Cisco IOS monolithic kernel does not implement memory protection for the data of different processes. The entire physical memory is mapped into one virtual address space. The Cisco IOS kernel does not perform any memory paging or swapping. Therefore the addressable memory is limited to the physical memory of the network device on which the operating system is installed. IOS does however support aliasing of duplicated virtual memory contents to the same physical memory.

This architecture was implemented by Cisco in order to ensure system performance and minimize the operational overheads of the operating system. The disadvantage of the IOS architecture is that it increases the complexity of the operating system, data corruption is possible as one process can write over the data of another, and one process can destabilize the entire operating system or even cause a software-forced crash.

In the event of an IOS crash, the operating system automatically reboots and reloads the saved configuration. In all versions of Cisco IOS, packet routing and forwarding switching are distinct functions. On router platforms with software-only forwarding e. This means IOS does not have to do a process context switch to forward a packet.

In routers with hardware-based forwarding, such as the Cisco series, IOS computes the FIB in software and loads it into the forwarding hardware such as an ASIC or network processor , which performs the actual packet forwarding function.

The number of IDBs present in a system varies with the Cisco hardware platform type. 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 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 addition, competitive router operating systems that emerged 10—20 years after IOS, such as Juniper 's Junos OS , were designed to not have these limitations.

The IOS XR development train initially used the real-time operating system microkernel QNX and a large part of the IOS source code was re-written to take advantage of the features offered by the kernel. 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.

I am concerned I will somehow screw up what is already working. Just to clarify, my "old" router is on the second floor of my unit which is in a concrete building and I want to install a second independent router downstairs as the E router signal is very weak when it reaches the first floor. I have tried an extender but it did not work out well. Feb 6, PM. Feb 6, PM in response to lilacsbloom In response to lilacsbloom.

Router setup is not my forte; however, my instinct tells me that you will need to set it up - the other question is and, again, not my forte : my ISP allows me to have one router. If I want another, I have to set up the first one as a "gateway" to send the signal to the second one essentially as an extender which you said did not work.
