Which command displays the status of the interface?

The command that displays the status of the interface is cphaprob -a if. This command is specifically designed to provide detailed information about all interfaces in a cluster environment, showing their operational status, IP addresses, and any relevant health indicators. By using the "-a if" option, you can view a concise overview of each interface's status, which is crucial for monitoring and troubleshooting network connectivity within a Check Point cluster.

Other commands may provide insights into various aspects of High Availability (HA) or cluster conditions but will not offer the direct and specific interface status detail that cphaprob -a if provides. For instance, cphaprob interface and cphaprob -I interface may refer to different functionalities concerning cluster management but do not focus explicitly on summarizing interface statuses the way the -a if option does. Meanwhile, cphaprob stat often delivers overall cluster status, which, while useful, is broader and less focused on individual interface performance. This distinction is essential for understanding the command's applicability in administering checkpoint interfaces.
