Like most software, the IOS requires updates to resolve security issues, defects and also to add additional features.
Updating the IOS on a Cisco 2960 is a straightforward procedure when connected to the Cisco 2960 command line interface (CLI) using a serial console cable.
The switch we’re going to talk about today is a 2960S switch.

It's been under continuous development since 1984, is a gigantic single image, and falls under the classification of monolithic monitor operating system, with run-to-completion scheduling, threading, and no memory protection.
The Cisco IOS (Internetwork Operating System) is a robust platform that provides a high level of reliable performance within most network infrastructures.
You manage everything from the primary switch and you never touch the “slave” switches.
So I recently ran into a situation where I had to upgrade the IOS on the switches.
One thing to also note that that as you might imagine, the code needs to be the same on ALL switches in your stack.
Luckily for us, there is a Cisco KB guide on how upgrade the code on all switches in our stack in 1 shot….its also just 1 command. Run it on your MASTER switch and we get the following options…as you can see we got a bunch of different places we can pull the image from (flash, SCP, TFTP, the usuals) and some options (show in slashes) like overwriting the existing image, specifying a directory, reload after specifying the image, etc. /destination-system specify destination system to receive software /directory Specify a directory for images /force-reload Unconditionally reload system after successful sw upgrade /force-ucode-reload Upgrade UCODE after successful sw upgrade and before an unconditional reload /imageonly Load only the IOS image(s) /leave-old-sw Leave old sw installed after successful sw upgrade /no-set-boot Don’t set BOOT — leave existing boot config alone /no-version-check skip version check that prevents incompatible image install /only-system-type specify individual system type to be updated /overwrite OK to overwrite an existing image /reload Reload system (if no unsaved config changes) after successful sw upgrade /safe Always load before deleting old version /upgrade-ucode Upgrade UCODE after successful sw upgrade (no reload) flash1: Image file flash2: Image file flash: Image file ftp: Image file Image file https: Image file rcp: Image file scp: Image file tftp: Image file After you pick your option sit tight for a while.This command shows us a summary of the switches in our stack. If R&S has taught us anything, geernally the higher the priority the better (wins the election).So this is why from 1-15, switch1 has won the election as is now the master of the stack.Things You’ll Need Instructions to Upgrade a Cisco 2960 IOS With a Console Cable 1. Enter a name for the connection in the “Name:” field presented in the Hyperterminal window that appears, and then tap the “Enter” key.Attach one end of the Cisco serial console cable to the 9-pin serial port on the Windows 7 computer. Select “Connect using:” and then choose the “Com port” in the drop down list, that is being used to connect the Windows 7 computer to the Cisco 2960, and then tap the “Enter” key. Select the “Bits per second:” drop-down box, and then choose the “9600” setting from the list that appears. Touch the “Enter” key and the Cisco command line interface (CLI) appears. Enter the “enable” command at the command prompt, and tap the “Enter” key. After the IOS image file has been transferred to the Cisco 2960, the switch automatically reboots and starts running the new IOS image.Also, just to be safe, reboot the switches to ensure the new version not only takes but doesnt cause any issues.Tags: Adult Dating, affair dating, sex dating
