We have a cisco switch c3750 with some HP hubs attached


We have one office that gets regular network disconnects


we have tried everything (changed port etcc.)


was wondering could there be a dodgy port on something on the network causing this


and if so what logs could I look at on the switch...


Im a cisco virgin and know nothing


I can see a very basic log on the switch

but does not seem to help me


any thoughts or direction


thank you

Hubs are a key word here. I would get rid of them and get some sort of managed switch. Could be a Spanning-tree issue. Is possible there is a network loop on one of the Hubs? When you run a SHOW LOGGING on the 3750, does it say anything about interfaces going down? Also, post a SHOW SPANNING-TREE.

But yes,would love to rid myself of hubs


My colleague mentioned that an network engineer had mentioned a rogue port or something, although why he did not act on this i do not know...
