Which command can be used to verify interface status quickly?

The command "show interfaces brief" is the most effective way to quickly verify the status of all interfaces on a Juniper device. This command provides a concise summary of each interface, including its operational status (up or down), administrative status, and some basic statistics such as the protocol state. This quick overview allows network administrators to swiftly assess the health and operationality of interfaces without diving into the more detailed information that can be found with other commands.

While commands like "show interface status" or "show ip interface status" may provide similar information, they may not be standard for Juniper devices, and their output may not be as succinct as that of "show interfaces brief." The "show operational interfaces" command is also valuable for more detailed output but is less efficient for obtaining a rapid overview of all interfaces as it typically generates more extensive information than the "show interfaces brief" command.
