Most builds of IOS include a Tcl interpreter. Through the CLI, the commands available to each privilege level can be defined. All commands are assigned a privilege level, from 0 to 15, and can only be accessed by users with the necessary privilege. 'Global configuration mode' provides commands to change the system's configuration, and 'interface configuration mode' provides commands to change the configuration of a specific interface. The set available is determined by the 'mode' and the privilege level of the current user. The IOS command-line interface (CLI) provides a fixed set of multiple-word commands. For the Nexus switches Cisco developed NX-OS, which is similar to IOS, except that it is Linux-based. Cisco eventually introduced the native mode for chassis, so that they only run one operating system. In early modular chassis network switches from Cisco, modules with layer 3 routing functionalities were separate devices that ran IOS, while the layer 2 switch modules ran CatOS.

The Cisco Catalyst series would for some time run the CatOS. The company acquired a number of young companies that focused on network switches, such as the inventor of the first Ethernet switch Kalpana, and as a result Cisco switches did not run the IOS. When IOS was developed, Cisco Systems' main product line were routers. Through modular extensions IOS has been adapted to increasing hardware capabilities and new networking protocols. The IOS network operating system was developed in the 1980s for routers that had only 256В kB memory and low CPU processing power.

Notable exceptions include ASA security products, which run a Linux-derived operating system, carrier routers which run IOS-XR and Cisco's Nexus switch and FC switch products which run Cisco NX-OS.

Although the IOS code base includes a cooperative multitasking kernel, most IOS features have been ported to other kernels such as QNX and Linux for use in Cisco products. IOS is a package of routing, switching, internetworking and telecommunications functions integrated into a multitasking operating system.

Please help to improve this article by introducing more precise citations. Suppose you want to mirror all the traffic from port Gi1/0/10 to Gi1/0/48 on the same switch.This article includes a list of general references, but it remains largely unverified because it lacks sufficient corresponding inline citations. SPAN copies all the traffic that comes in and out of source ports or source VLANs to a destination port on the same switch for analysis.

That's all, now Wireshark should be able to capture all the traffic that comes in and out of the server port. Monitor session 10 destination interface gi1/0/10 switch-2 configuration Monitor session 10 source remote vlan 100 Monitor session 10 destination remote vlan 100 switch-1 configuration switch-2 Monitor session 10 source interface gi1/0/10 It is recommended to configure an RSPAN VLAN before you configure an RSPAN source or a destination session. This blog post shows an example of mirroring all the traffic from a server to a workstation connected to a different switch. RSPAN does not affect the switching of traffic on the source ports or VLANs that are being used. RSPAN copies all the traffic that comes in and out of source ports or source VLANs to a destination port on a different switch for analysis.
