138:, 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. Earlier, Cisco switches ran CatOS. Cisco IOS is a package of routing, switching, internetworking and telecommunications functions integrated into a multitasking operating system. 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. Cisco Catalyst products run IOS or a Linux-derived version called

Complex configurations are best created using a text editor (using a site standard template), putting the file on the TFTP server and copying it to the Cisco device. However, it can be noted that a TFTP server can present its own security problems.
325:
As each switch contains the entire configuration for the stack, one of the benefits of this technology is the ability to replace a faulty switch (any—including primary) with a new switch. The stack will configure the new switch on-the-fly to accommodate minimal downtime and reduce maintenance effort
321:
If one switch fails, the remaining switches will continue to operate by bypassing it. If the primary switch fails, another switch in the stack will automatically take over as primary. This feature means greater redundancy, as one switch's failure will not bring about a failure of the entire stack.
373:
In general, switch model designations start with WS-C or C, followed by the model line (e.g. C9600). A letter at the end of this number signifies a special feature, followed by the number of ports (usually 24 or 48) and additional nomenclature indicating other features like UPOE (e.g. C9300-48U).
369:
There are two general types of
Catalyst switches: fixed configuration models that are usually one or two rack units in size, with 12 to 80 ports; and modular switches in which virtually every component, from the CPU card to power supplies to switch cards, are individually installed in a chassis.

are technologies offered by Cisco
Systems that allows some models of Catalyst switches to operate as though they were one switch. One switch from the stack will act as the primary switch. The primary switch will maintain the stack and allows for configuration and monitoring of the whole stack as
