You could use the free Cisco Network Assistant (CNA) to manage the switches. But if you really want to learn the stuff, you should use the CLI.

For the sudden restart, that could just be a buggy firmware. Which version do you run on your 3750?

@ Karsten lwen , thanks for your knowledge. i look forward on that  . currently we have Switch   Ports  Model              SW Version              SW Image
------   -----  -----              ----------              ----------
*    1   24     WS-C3750G-24T      12.2(35)SE5             C3750-IPBASE-M 

And also i would recommend you , suggest me the Best L3 switch for Medium business . so will go for accordingly to my scenario .

I would upgrade the switch to 12.2.55-SE9 which is the newest release for that switch.

If you want to replace the switch, I would first look at the Catalyst 3650. Based on your traffic and size of network, the SG500 series from the small-busInes line of switches could also be a good choice.
