We have a problem this morning where all users lost network connectivity for about 1 min. When I went to the comms everything appeared ok and it was working again right away. Reading up on the problem, some reports say this sort of problem may be caused by a network loop or a arp problem. I don't have the password for the web interface but i don't think the switches are NOT managed from the web interface anyway, well not from what i remember.

I find cisco switches quite difficult to work with because there is never any information available on them and they tend to make everything more complicated than it needs to be. While other switches they have a web interface that actually has functionality or an application that allows you to configure the switch. cisco switches rely on backwards command line options. I have gained access via telnet and have found a list of commands but can not find anything on viewing logs or troubleshooting this sort of issue. I should add that the switches have been up for over 2 years and this is the first issue we have had and at the moment everything is working ok.

Does anyone have any tips ?

edit: ok nevermind. I had the incorrect model and this is why i could not find any documentation or anything. stupid me.

Well, first problems first, complaining about the web interface is comical. Learn the IOS CLI, seriously.

Secondly, do you mean 3750? I thought the 3900 series was an ISR?

Are you a massive troll or just stupid? Every time I see your posts about this sort of thing I just feel sorry for whatever companies you are involved with. Your statement there is just the most ludicrous thing I have seen all year

I'd consider another career path, maybe tapestry - although get a machine as I hear needles are backwards too

yer tbh if you dont know the iOS CLI then you shouldnt be touching Cisco switches... If I was your boss I would be telling you to never ever touch my switches

Yes it was a 3750. Stupid me. But still not much help because i think cisco switches require an external syslog server to get logs, well from what i have read.

Well yea, i am not a fan of cisco. All their commands are backwards and the web interface is just for show (ie no config available from it)

I just installed the network assistant v5 which surprising allows the config to be modified from within the application. I am quite impressed with the network assistant application.

Still not sure what caused the glitch as everything looks ok on the switches.

I always found cisco devices to be designed to be overly convoluted but my theory was always that they are designed that way so that they could get silly IT guys to spend £10k on certifications lol. But everyone who owns cisco switches would rather spend loads of money on overpriced cisco specialists to come in and do basic tasks like update firmware, this imo is because of the way they design the switches.

See since I know CLI I would now be monitoring the debug information to see if I could spot anything maybe output it to a text file for my analysis checking all switching, routing and VLAN information because I know CLI.

Well i am not cisco specialist and do not realy have that much interest in learning the cisco CLI. I just thought there might be a easy way to view logs but it does not appear to be the case.

I tried reading through the documentation but at 1500 pages that is like a full time job. I have loads of other things on my plate at the moment.

But thanks for the tips stelly appreciate it.
 
Are you trolling? Surely you are not so misguided. There is a huge amount of documentation on the 3750 switches and if you have any research skills worth mentioning you should be able to find what you need quite quickly...
 
groen are you sure you've chosen the right career?

There's nothing wrong with Cisco web interface or CLI - very logical if you take the time to look at it.
 
Okay guys,

I think that Groen knows that he is a networking noob for not knowing CLI I dont think that we need to rub it in, I think that he knows that he is wrong and that he will be looking at learning CLI as any network admin needs to know CLI from the off.

It isn't about what he does and doesn't know - its the casual way he's come in here and started ****ging off something through total and utter ignorance. Such a poor attitude and it isn't the first time.

If I was your boss you would be putting you on a time out. Fiddling with something you have no idea about is very silly.

The Cisco cli is easiest one of the best ways of configuring networking equipment about. Many other companies have tried to copy it and failed. My advice would be is to learn it. Using the web GUI also makes your config very messy and dirty and GUI has no regard for structure.

In your case my first command to run would be "show log" to simply show the log file.
