Which command would you use to check the current interface status?

The command "show interfaces status" is used to check the current status of interfaces on a Juniper device. This command provides vital information about each interface, such as its operational status, administrative status, and other pertinent details related to the interface configuration. Using this command, network administrators can quickly assess whether interfaces are up or down, as well as other important metrics like link speed and duplex settings, which are essential for troubleshooting and monitoring network health.

The other commands, while they may seem related, do not provide the same level of detail regarding interface status. For example, "display interface state" is not a standard command within Juniper's command structure. Meanwhile, "show interface detail" typically provides in-depth information about a specific interface rather than a summary of all interfaces' statuses. Lastly, "get interface information" doesn't follow Juniper's command syntax and hence won't yield the desired results.

Thus, using "show interfaces status" is the most direct and effective way to obtain the current status of all interfaces on the device.
