Web Console 404 error - no web ui OS

[gsrel]

Just to mention off the batt.. I've never used a cisco device so excuse my ignorance

Long story short is that I have a 3750g that I would like to install into a Ubiquiti environment to provide POE functionality to some cameras and basic switching.

I was able to get it configured through putty but It would be nice to have a web ui for simplicity sake. The current unit has the OS listed in the normal 3750 page and not that of the 3750g. Is there any reason to stick to 12.2.55 or can one go to 15.2.4

Is there anything that I need to watch out for when upgrading the OS file (delete the old) and is there a writeup on the steps one needs to take?  I heard that Tftpd64 is the way to go when using a .tar file.

Downloading a new version of code from Cisco requires a current support contract. So an important first question is whether you have a current support contract.

I will leave it up to other of my colleagues in the community to make suggestions about specific versions of code since I have not looked carefully at this model recently.

I will comment that the common (and full function) method of configuring and managing these switches is via the command line (putty, etc). There is a web ui but my memory is that it is not as full function as the CLI. If you do want to get the web ui then one thing to know about is the difference in upgrading code using the bin file or upgrading code using a tar file. Upgrading using the bin file restricts you to using CLI. If you want the web ui then upgrade using the tar file. And Tftpd64 is a good implementation of tftp and is good to use for either the bin or the tar upgrade.

If you are going to do a code upgrade I would offer these suggestions:

- read the release notes for the version you will upgrade to, especially note any restrictions that they mention and any discussion of what changes in the new release.

- make sure that you have a good backup of the current running config.

- it is good to have a backup copy of the current version of code running on the switch (back it up to the tftp server you are using in case something happens to your current version.

I was able to download the following Tar files using the links above with no issues, perhaps no contract is needed as they are older units?

I wonder which one is best to go with

IP BASE WITH WEB BASED DEV MGR

c3750-ipbasek9-tar.122-55.SE12.tar

Release Date: 09-Oct-2017

DRAM:128
FLASH: 32

UNIVERSAL WITH WEB BASE DEV MGR

c3750e-universalk9-tar.152-4.E10.tar

Release Date: 07-Apr-2020

DRAM: 256
FLASH: 64

I think I answered my own question.. the switch only has 32mb from what I can tell

[Richard Burts]

Thanks for the update. It is interesting that you could download the image without a support contract, but glad that it did work for you. Yes I believe that you have answered your own question. Read the release notes carefully. And good luck with the code upgrade.

Unfortunately its giving me an insufficient space error when trying to tftp (I had to use Serva to get it running).

Im not sure which of these files I can delete to obtain sufficient space that wont brick the unit prior to update. The Tar file is 15.5mb. Unless of course im an SOL which in that case it would suck as a web interface would be a lot easier for me. This switch will be used at my home for basic functionally.

I found this guide but im not sure which if I need the ipservices, EC2 file installed?

The output you posted shows a directory for 12.2.25. This is older than the others and you are not using it. So check what is in the directory (should be the bin file and probably are other files) and how much space you would reclaim if you delete the directory and its content.

Another possibility would be the bin file for 15.0.2, which looks like it would give you enough space if you delete it.

If you think that there might be anything in either of those files that you might need (as an insurance policy in case something goes wrong in the code upgrade) you could save those files to your tftp server before deleting them.

Thank you, I removed the services file which allowed me to update.

Only issue now is that this doesn't support anything past Windows xp/2000 and older browsers. I suppose I will need to install an xp virtual machine and go from there

[Richard Burts]

Thanks for the update. Glad to know that you were able to do the update.
