Example of Error Due to Issuing a Layer 3 Command on a Layer 2 Interface
If an interface is in the incorrect layer mode for a given command, an error message is displayed (shown
in bold). In the following example, the
ip address
command triggered an error message because the
interface is in Layer 2 mode and the
ip address
command is a Layer 3 command only.
Dell(conf-if)#show config

addresses on a single interface.
