If your switch is a managed switch like Cisco Catalyst series, they would have a web based administration interface which gives you statistics and reports, possibly even log files.

Otherwise, your options are limited to using a set of network cables that are known to be working and a couple of workstations and test connectivity between the workstations and transfer a couple of large files between the workstations.

Of course, on the front panel of the switch itself, the indicator light tells you if the particular port is connected to the workstations at the other end of the patch lead and the network cable. Depending on the model of the switch, you may even see some error indicator, like yellow light instead of green, if there excessive errors are detected.

If all else fails, read the manual that came with the switch. It may have also come with some diagnostic software CD.

yes there is ...in fact there are :
1. check the port leds . usually a red or amber colour means a fault !
2. either thru the web interface ( if you know the ip of the switch ) or thru the console port get to the management menu ( you need the admin paaaword) . There go down to the ports/interfaces and ask for an error report or a log of the switch ( since boot up ) . Any reported errors across a port(s) will pinpoint the fault .
3. Get a straight and a cross cable . Connect a laptop or a desktop with the staright cable and check the colors on the NIC leds . Get another switch and hook it up to the suspected switch . Check again the leds . For led colours ( or no light ) follow the instructions on the switch/manual .
4. Finally , get a ip scanner or lan analyzer software . Install it and Connect the port to the suspected port of the switch . Run a ping/alive test and check the log . Faulty jabbers or runts will be reported .
REPEAT the procedure for every suspected port. Be warned that if more then one port is faulty you may need to throw away the whole switch altogether , to have a trusted error free net .
