Set Login Restrictions to protect Cisco IOS Routers & Switches


  1. A good article, but it’s worth mentioning that the “login” command syntax tree isn’t available in a lot of IOS versions, perticularly the older versions on routers and switches. Version IOS 12.3 and up as far as I know are alright.
