What is Cisco IOS?




Cisco IOS stands for Cisco Internetwork Operating System. It is the software that runs on most Cisco devices, such as routers, switches, firewalls, and access points. It provides the functionality and features that enable you to configure, manage, and troubleshoot your network devices.


Cisco IOS has a modular architecture that consists of three main components:


  • The kernel: This is the core component that handles the basic functions of the device, such as memory management, process scheduling, interrupt handling, and device drivers.



  • The system image: This is the file that contains the Cisco IOS software and the feature sets that you can use on your device. The system image file name usually follows this format: platform-feature-set.image-type.release.version.extension. For example, C3725-adventerprisek9-mz.124-15.T10.bin is a system image file name for the Cisco 3725 router with the Advanced Enterprise Services feature set in compressed format with a release number of 12.4(15)T10.



  • The configuration files: These are the files that store the settings and parameters that you configure on your device using commands or graphical user interfaces (GUIs). There are two types of configuration files: startup-config and running-config. The startup-config file is stored in non-volatile memory (NVRAM) and contains the configuration that is loaded when the device boots up. The running-config file is stored in random access memory (RAM) and contains the configuration that is currently active on the device.



Cisco IOS has many features that make it a powerful and versatile operating system for network devices. Some of these features are:


  • Command-line interface (CLI): This is the primary way of interacting with Cisco IOS devices using commands that are entered in different modes, such as user mode, privileged mode, global configuration mode, interface configuration mode, etc.



  • Graphical user interface (GUI): This is an alternative way of interacting with Cisco IOS devices using graphical tools, such as web browsers or desktop applications.



  • Security: This includes features that protect your network devices and data from unauthorized access, such as passwords, encryption, authentication, authorization, accounting (AAA), firewall, VPN, etc.



  • Routing: This includes features that enable your network devices to forward packets between different networks based on routing protocols, such as static routing, RIP, OSPF, EIGRP, BGP, etc.



  • Switching: This includes features that enable your network devices to forward packets within the same network based on switching protocols, such as VLANs, STP, VTP, EtherChannel , etc.



  • Quality of service (QoS): This includes features that enable your network devices to prioritize and manage traffic based on different criteria, such as bandwidth, delay, jitter, packet loss, etc.



  • Network management: This includes features that enable your network devices to monitor and report their status and performance using protocols, such as SNMP, Syslog, NetFlow, etc.



  • Network services: This includes features that enable your network devices to provide or support various services for your network, such as DHCP, DNS, NAT, NTP, FTP, HTTP, etc.



As you can see, Cisco IOS is a very comprehensive and flexible operating system that can meet the needs of any network environment. However, not all Cisco IOS features are available on all Cisco devices. Depending on the device model and hardware specifications, you may need to choose a specific Cisco IOS feature set that suits your device and network requirements.

What are Cisco IOS feature sets?




Cisco IOS feature sets are collections of Cisco IOS software features that are grouped together based on the type of device, the type of network, and the type of service that they provide. Cisco IOS feature sets are also known as software images or software packages. They are identified by a unique name that indicates the platform, the feature set, the image type, the release number, and the extension.


Cisco IOS feature sets can be classified into three main types:


  • IP Base: This is the basic feature set that provides the minimum functionality and features for IP routing and switching. It includes features such as static routing, RIP, OSPF stub, VLANs, STP, QoS, SNMP, etc. It is suitable for small to medium-sized networks that do not require advanced services or protocols.



  • IP Services: This is the intermediate feature set that provides additional functionality and features for IP routing and switching. It includes features such as EIGRP, OSPF non-stub, BGP, IS-IS, multicast routing, policy-based routing, IPv6 routing, etc. It is suitable for medium to large-sized networks that require advanced routing and switching services or protocols.



  • Advanced Enterprise Services: This is the advanced feature set that provides the most comprehensive functionality and features for IP routing and switching. It includes features such as MPLS, IPsec VPN, SSL VPN, firewall, IPS, voice over IP (VoIP), video over IP (VoIP), wireless LAN (WLAN), etc. It is suitable for large-sized networks that require complex and integrated services or protocols.



Cisco IOS feature sets can also be customized or upgraded by adding or removing specific features or modules.
