Which command shows running Netflow configurations in real-time?

1. #show ip cache flow

2. #show ip flow interface

3. #show ip flow export

4. #show running-config

The correct answer is: #show ip cache flow

The command that shows the running NetFlow configurations in real-time is indeed one that allows you to monitor flow information being collected by the NetFlow feature on a Cisco device. The correct command provides real-time statistics on active flows and cache entries, making it valuable for network analysis and troubleshooting. Using the command to show IP cache flow allows administrators to view the current status of flows being processed by the NetFlow engine. This includes metrics such as the number of flows, the amount of data transferred, and connection details. This real-time capability enables network engineers to make informed decisions based on current traffic conditions and performance metrics. While other commands related to NetFlow also serve important purposes, they do not provide a real-time view of configurations or active flow data. For instance, one command might focus on exported flows rather than the active caches, while another might simply display interface settings but lack the real-time analytical capabilities of the correct command.
