The popular standard, used most often with the free Adobe® Reader® software.This e Book requires no passwords or activation to read.In most cases, the technology for the Catalyst Switch was developed separately from Cisco′s router technology.The Catalyst switches originally ran software called Cat OS rather than the more widely known Cisco IOS software used by routers.Unfortunately fixed configuration switches require the use of x Modem to restore a corrupt or missing IOS images unlike the Cisco 4500 and Cisco 6500 Series supervisor engines which use compact flash cards Step 1. This typically involves holding down the STAT button on the front of the switch when plugging in the power.You can check out the required procedure by clicking HERE! I have a Cisco Catalyst 2960S switch that is currently running software version 12.2(55)SE3 The most current software listed on Cisco's website is 12.2.58-SE2(ED) and 15.0.1-SE2(ED) Do I need to remain on the 12.x series of software, or can I use the 15.x software? IOS 12.2(58) and higher have major memory leak issues that can lock you out of the switch (console included) and should be used with caution. For the least amount of upgrade surprise, I would go to 12.2(largest number possible) SE(largest number possible).
Recovering the Cisco IOS image on a Cisco switch is one of those tasks that is nice to know and not need it then need it and not know it.In the field you may find yourself faced with a Cisco switch that cannot boot up or crashes when booting up due to a possible IOS Image corruption.Recovering the Cisco IOS Image on a fix configuration Cisco Catalyst Series Switch is quite a bit different and more of an “old school” way of doing an IOS image recovery.If you need new features, doing it on one switch only is a bad plan.
That will depend on what you are doing with the switch. If your switching is fairly static and you have no need for new features, then stick with the latest 12. You could probably upgrade it now and never touch it again unless there is a security flaw you need to plug.You will learn how to configure routers and switches for advanced functionality.
