New Cisco routers have built in software’s to capture the packets that are traveling over the network. You just need to plug-in your system to any of the switch port and access the switch to start sniffing data packets. If you are getting some problems, you can get help from CiscoDealer.com. 

If you already having a switch or buy a used Cisco switch then you have to upgrade the operating system of your Cisco switch. To upgrade your Cisco switch you must send your switch back to the company where they can upgrade your switch. The new switches are bit expensive that can handle a network of 100 to 200 systems. The best thing is that you should buy a new switch instead of upgrading an old one.
