Cisco 2501 Router IOS Upgrade Procedure Simplified!

By Bob Marshall.

Ok, one of the most mutual question we get is how do I upgrade the ios on my cisco router? I may refer you to the documentation on cisco's website on in which way to do this, but it seems as although for the modern ccna student that this just doesn’t give you complete details you must with great success upgrade your ios.

I altogether comprehend this as their instructions are written for an individual who is already intimate with cisco routers and switches and who is in all likelihood already a cisco ccna. Now I may similarly suggest to you that it’s not of the utmost importance that you upgrade the ios on your cisco router as soon as you get it. You see, the commands that reside in version 11. X are 95% the same as in 12. X.

The cisco ccna exam in truth focuses on the center commands that have been there for years. So again, there’s no need for a prompt upgrade day one when you get your cisco router from 11. X to 12. X ios. Take your time and become comfortable with the router and the commands.

Otherwise you can mess up the upgrade and sit there cursing at the router as you attempt to work out in which way to get ios back on the router that you deleted by fault. But don't worry; you are going to be capable to recover whether or not you deleted the ios by fault too. It’s just a bit dissimilar of a routine. Now when you feel you’re fine-looking comfortable with the ios commands, then carry out the cisco router ios upgrade. After all, you will require to be capable to finish such like practice to pass the cisco ccna exam.

Now in this article, I am going to make an assumption that you have our study cd which has a great deal of of these files on it. Whether or not you don't have our cd, you may buy it or search the web for stuff like the solarwinds tftp server. Ok, here we go! Here are the steps to start out. . .

. 1) on the cd, follow the link to install the trial version of the solarwinds tftp server. You may access this by inserting the cd in your computer, automatic-running the cd and you ought to see the ciscokits splash screen. On the splash screen you ought to see a link for "handy programs". Click that link and then follow the link for the install of the solarwinds tftp server.

2) after you install the tftp server, you will copy the 2500 ios file that you want to upgrade the router with to the c:tftproot folder whether or not you followed the default install directories for the tftp server. This file is a. Bin(binary) file so you wouldn’t be capable to open. Some persons will tell us that there’s a problem with the file as they can't open it. You’re not supposed to be capable to open and launch it as it’s not an.

Exe file. 3) launch the tftp server. 4) once in the tftp server application, go beneath file, click configure and click the start out services button. Click ok. You ought to see in the bottom of the tftp server application box that it says service status is "started" and you ought to see the ip address(ex.

192. 168. 1. 100) of the tftp server to the left of that along with the c:tftproot folder as the default folder to the left of that(again, that is where the tftp server will seek for the. Bin ios file).

Whether or not you don’t see all that, you have missed a step someplace so please go back and verify your steps. 5) this step could go more than one dissimilar ways. 5a are going to be the steps whether or not you already have a good version of ios on the router. 5b are going to be whether or not you without advance planning deleted the ios from the router. Now in my example here I am going to assume you have a great deal of kind of switch or hub that you have the cisco router and your pc connected into.

I will similarly assume you’re using an internal ip address strategy of 192. 168. 1. X. The address for the router are going to be 192.

168. 1. 80 and the ip address of the tftp server are going to be 192. 168. 1.

100. Whether or not you’re not using that ip schema, then you will require to alter these instructions hence to fit your ip schema. 5a) boot the unit usually. You ought to be brought to a regular user mode. In step 7, we will get you into privileged mode.

5b) boot the unit and whether or not you have no ios on the flash, it will boot using the boot effigy from rom. You will acknowledge this as your immediate will look like this: router(boot) 6) put a transceiver on the aui port. Hook an ethernet patch cable to the transceiver and the other end to the hub or switch your computer is connected to. 7) the following set of commands we are doing to configured an ip address on the cisco router. We must have an ip address assigned to the ethernet interface or we wouldn’t be capable to commune thru ip with the tftp server.

Do the next commands: en config t int e0 ip address 192. 168. 1. 80 255. 255.

255. 0 no shut exit exit copy tftp flash 8) it will ask you the name of the remote host. Address or name of remote host []? 192. 168. 1.

100 put the ip address of your tftp server. 9) next it will as you the source file name. Source filename []? C2500-is-l. 123. 24.

Bin it’s the name of the ios file you copied over to the c:tftproot folder. 10) next it will as you the destination file name. Destination filename [c2500-is-l. 123. 24.

Bin]? Y hit y for yes to utilize the current file name. It can ask you to assert. Enter y for yes. 11) it will then ask you whether or not you want to erase the current flash file strategy. Enter y for yes.

It can ask you to assert a second time, whether or not it does, enter y for yes again. Erase flash: before copying? [confirm]y 12) next is must start out the flash erase as seen beneath and you will see the file copy routine as mentioned by the exclamation points. Erasing device. . .

Eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee eeeeeeeeee. . . Erased erase of flash: finish loading c2500-is-l. 123.

24. Bin from 192. 168. 1. 100 (thru ethernet0):! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! 13) whether or not you start out to see a bunch of periods, then that means you have a great deal of kind of connectivity issue.

Here are the things I suggest you consider: a) is the link light on the hub or switch for both the pc connection and the cisco router connection? B) from a command immediate on the pc, may you ping the ip address of the pc? C) from a command immediate on the pc, may you ping the ip address of the cisco router? D) from hyperterminal on the router, may you ping the ip address of the cisco router? E) from hyperterminal on the router, may you ping the ip address of the pc? F) is the service still started on the tftp server and is the ip address still 192. 168. 1. 100? These things must start out to give you an idea of where the problem can be. .
