Probe: Command to query status of probed interfaces (RFC 8355)

You can use the probe command to query the status of the probed interface. The proxy interface resides on the same node as the probed interface, or it can reside on a node to which the probed interface is directly connected. The Probe command helps to capture the interface details such as system statistics, and interface state (active/inactive), irrespective of whether the network family address configured is IPv4 or IPv6 on the probed interfaces. To enable the probe command, configure the extended-echo statement under the [edit system] hierarchy.
