Hello friends, I have network configured for my office which has around 20 computers. All the computers are connected to two Cisco switches. Recently I upgraded the operating system on some of the computers and after that the switches started to reboot on its own which is creating problems in my office network. One of my friend suggested that I should get the IOS of the switches upgraded. Therefore want to know How to upgrade IOS on a cisco switch. Any suggestions/solutions about the problem are welcome. Thanks in advance.
