Router and switch boot up process

just confirming if router and switch has the same boot up process…or is there any difference in the booting process of router and switch??


Hello Sumant

Yes, for the most part, a Cisco router or switch running IOS will have the same major components of the boot up process, specifically the Power On Self Test or POST takes place. For two low end devices such as a 1941 router and a 2950 switch, the boot up process will be almost identical. However, as you get to higher end devices, such as ASRs and 6800 series Catalysts, the boot up process becomes more specialized and can differ widely. Take a look at these two lessons that have to do with the boot up process of IOS routers and switches respectively for more information.

I hope this has been helpful!
