Dropping Network in Hardwired System.

This is a big advantage of a managed switch over a consumer unmanaged switch.

An unmanaged switch either works or it doesn't; if it doesn't there's no way to find out why - you just have to guess and randomly try things.  If the managed switch has a problem you can ask it why.

Well chaps I can report some progress, I managed to log in via the IP address and found some pages of stuff, frankly it is baffling, I might ask in the office for some help, but I fear the Cisco is destined for the loft as despite it being a nice bit of kit it is completely unfathomable to me.

I don't normally admit defeat but I think Im going to stick with a cheap un managed switch.

If the Cisco has been reset to factory defaults, it will essentially work as an unmanaged switch, so I don’t think there’s anything to gain by changing it for a cheap consumer unmanaged switch. 

Having said that, logging into a 2960 via the CLI to access its many features is certainly not intuitive. It took me a fair while, and quite a bit of googling, just to figure out how to change a few settings.

Hi Chris,

Thank you for your words of encouragement, I will try to persevere. It is a bit like a foreign language to me though, I don't even know what questions to ask of Google or "in this place"!

Earlier in the thread mention was made of locking the speed and duplex i think perhaps i should start with this?

My temporary cheapo switch does seem to work. 

Roog, like you I got myself a s/h Cisco 2960 about a month ago. 

I found a manual at Cisco's homepage, Express Setup. Here you can find an easy description on how to 1) Reset the unit to factory standard, and 2) Do a simple set up after resetting. 

I followed the instructions and I was up and running in a very short time. Well, I could have been, because I had no connection through the switch after putting it between the router and the NAS and streamer. It turned out that I only needed to power off router, switch, NAS and streamer, and gradually turn everything on again, in said order, waiting a few minutes from one to the next. 

In the manual is also described how to log in to the switch in a browser window to see info on the ports and apply some settings if you should wish. I haven't changed anything, I think, except for maybe setting up a password during the first setup. 

Maybe I have just been lucky and it's not always as simple as this. But I can recommend the Express Setup guide, was easy to find via Google.

Thank you Claus, your help is appreciated.

I did indeed find the express setup guide, i reset my Cisco and tried to login using the IP 10.0.0.1 as suggested by cisco, to be confronted with a password login page.

After about and hour of faffing about on the web i tried a number of login options put forward by contributors and finally found one that would let me in.

The page i have found doesn't seem to let me change anything, which is probably just as well given that I didn't have a clue what any of it meant. :0(

Having done the reset, UPNP worked for about an hour then it started dropping the connection to the SU, switching to TIDAL seemed to work for the next hour.

The connection uses the same Port, cable and SU!  why should it work with TIDAL and not UPNP?

I guess I need to recoup my energy and delve in again afresh

 

ROOG, I suspect your switch, unless not faulty, has detected a fault on on the affected connection and disabling... however if not affecting operation on a basic switch you could argue the fault if present is not causing you an issue... therefore I would ignore... if it was me then I would want to find out what is wrong.. However to use the switch as a diagnostic tool (the real purpose of a managed switch) then you will need to borrow some expertise to work out what is what... in all honesty it’s not a quick google task and possibly beyond what is possible on this forum.

BTW one really needs to telnet or SSH into the switch to effectively use command line interface, the web interface is there to be a simple basic status guide and basic profile alignment means rather than specific configuration and diagnostics. 

 

DH & SIS Thank you for your helpful comments. I asked for a little advice from our work IT people yesterday evening and they showed me how they can access their Cisco switches. The interface that appeared on their screen was much more intuitive than the one I accessed.  I suspect this was some form of basic level access, but I could see that it allowed changes to speed, duplex and PoE. 

Incidentally, like you chaps, they suspect a faulty cable, a short in a connector, faulty SU or a loop in the system shutting down the port.

The difference, they used a windows based PC and I used my PC running Linux, (no windows) perhaps i need a normal PC? 

I have been looking to buy one because I would like to try 4.6 on my SU and I don't fancy trying this update using the windows emulation on my Linux machine!
