Hi everyone. Lately I bought on a garage sale two cisco switches. Cisco Catalyst 2950T and 2924XL both are 24 ethernet port (with 2x 1gb port on 2950T). I would like to update software on these devices if it's possible. I tried Cisco Network Assistant to search for the device and found 2924xl accessible from this program and web page. 2950t seems like, beeing detected but cannot access the webpage or any configuration. What is a best way to load a firmware for these switches. How to know which firmware will be a best choice. ?
For the Cisco Catalyst 2950T 24 I see one firmwares in cisco directory. (BTW what is a difference between crypto and non crypto image ?) Should I load bin or tar ?
C2950 EI AND SI IOS CRYPTO IMAGE - c2950-i6k2l2q4-mz.121-22.EA14.bin
C2950 EI AND SI IOS CRYPTO AND WEB BASED DEVICE MANAGER - c2950-i6k2l2q4-tar.121-22.EA14.tar
C2950 EI AND SI IOS IMAGE - c2950-i6q4l2-mz.121-22.EA14.bin
C2950 EI AND SI IOS IMAGE AND WEB BASED DEVICE MANAGER - c2950-i6q4l2-tar.121-22.EA14.tar
What is a difference between IOS CRYPTO and non CRYPTO images ?
which one should I choose and what is a best way to load this firmwares. Cause 2924XL is accessible from Cisco network asistand I can try to upgrade 2924xl from it. Since 2950T is not accessible from http, telnet (showing that password is required but none is set & disconnects by itself) can i update it from console ?
I've seen that Cisco Network Assistant is able to load tar as a firmware when upgrading. Bin file is a exacly the same as tar but other extension or there are some other differences also ?
maybe let's try with your help update the 2924xl. There are two versions of that device. Seems like one has less flash space than the other. How can I check it which version do I have to not brick the switch ?
Re: Old Cisco Switches - Firmware upgrade question.
Ok somehow I managed to update my C2950T to newest possible software but. Device is not accessible from ethernet side (www, telnet, cisco assistant). But it seems to be working - kind a. I've connected to its console port and copied the bootlog from the device.
Why www site is not available as it used to be earlier. Also cisco network assistant detects the device but it also cannot connect. ?
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
