Which piece of information is NOT typically included in the output of the show ip interface brief command?

The "show ip interface brief" command is a common command used in Cisco networking devices to provide a summary of the IP interface status and configuration. When you execute this command, it typically displays several key pieces of information about each interface on the router or switch.

The command output includes the IP address assigned to each interface, enabling you to quickly see which IP addresses are in use. It also shows the physical status of each interface, indicating whether the interface is up or down. Additionally, the protocol status indicates whether the network layer protocol, such as IPv4, is operational on each interface.

Administrative distance pertains to routing protocols and is a metric used by routers to determine the trustworthiness of different routes learned from various routing protocols. This information is not relevant to individual interfaces' operational status and configuration, which is the focus of the "show ip interface brief" command. Consequently, administrative distance is not included in the output of this particular command.
