The front of a Catalyst 3750G switch, with 48 interfaces for Ethernet over twisted pair and four interfaces for small form-factor pluggable transceivers.Īll models have basic layer 2 functions and are capable of switching Ethernet frames between ports. Legacy models supported a variety of interfaces, such as Token Ring, FDDI, Asynchronous Transfer Mode and 100BaseVG, but are no longer sold by Cisco Systems. Other models can support T1, E1, and ISDN PRI interfaces to provide connections to the PSTN. Interfaces Īs Catalyst devices are primarily Ethernet switches, all modern Catalyst models have Ethernet interfaces ranging from 10 Mbit/s to 100 Gbit/s depending on the model. The newer Catalyst 9000 family uses the Cisco IOS XE operating system. Cisco renamed it to CatOS when they acquired Crescendo and later still to Cisco IOS as the operating system was extended to other Cisco products. It was originally called XDI by the switching company Crescendo Communications, Inc.
#CISCO 2960 SWITCH SETUP CODE#
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.Ĭisco Catalyst products run IOS or a Linux-derived version called Cisco IOS XE. Cisco IOS is a package of routing, switching, internetworking and telecommunications functions integrated into a multitasking operating system.
#CISCO 2960 SWITCH SETUP SERIES#
The Catalyst 2960-L SM Series of switches is an example of a Cisco Catalyst switch that allows this style of GUI via HTTP.Ĭisco IOS, formally the Cisco Internetwork Operating System, is a family of network operating systems used on many Cisco Systems network switches, routers, wireless controllers and wireless access points. Some newer Catalyst switch models (with recent versions of the Cisco IOS) also allow web-based management using a graphical interface (GUI) module which is hosted on a HTTP server located on the switch.
#CISCO 2960 SWITCH SETUP SOFTWARE#
Native IOS can also be found with newer software versions that have eliminated CatOS entirely in favor of IOS, even on hardware that originally required CatOS. In some cases, particularly in the modular chassis switches, a configuration called 'Hybrid' has emerged - this is where the layer 2 functions are configured using CatOS, and the layer 3 elements are configured using IOS. However, this has changed as the product lines have merged closer together. The Catalyst switches originally ran software called CatOS rather than the more widely known Cisco IOS software used by routers. In most cases, the technology for the Catalyst Switch was developed separately from Cisco's router technology.
