Solution

  • The Cisco prompt with the "#" means you are using a switch with IOS, but the "set" commands are for the older Cisco switches that use CatOS. You need to look up the IOS commands to accomplish what you are trying to do. The commands available for the switch will vary based on the switch model and IOS version.
