Which CLI command should be used to ensure VMAC mode is enabled on all cluster members?

To ensure VMAC mode is enabled on all cluster members, the correct command involves using "fw ctl get int fwha_vmac_global_param_enabled" followed by an expected result of 1. This command specifically checks the global parameter associated with VMAC (Virtual MAC) mode, confirming whether it is indeed enabled.

The context of this command is crucial as it provides direct insight into the status of VMAC across the cluster. The output of '1' indicates that VMAC mode is actively enabled on the cluster members, which is essential for the proper functioning of the cluster in a Check Point environment. VMAC allows for more efficient use of MAC addresses in a clustered environment, enhancing network performance and redundancy.

In contrast, other options may involve other commands that do not specifically verify the VMAC status in the same way. For instance, setting parameters or checking the interface states of cluster members does not provide the immediate confirmation needed for the specific task of ensuring VMAC is enabled across all members.
