At which configuration hierarchy level is a static bridge table entry configured?

The configuration of a static bridge table entry is done at the ethernet-switching-options hierarchy level. This level is specifically designed for settings and features related to Ethernet switching, which includes the management of bridge tables.

When configuring a static bridge table entry, you typically specify which MAC addresses are statically bound to which ports on the switch. This is critical for ensuring that traffic destined for a specific MAC address is forwarded out the correct port, enhancing network efficiency and security by preventing the learning of dynamic MAC addresses that can change.

The other options relate to different aspects of device configuration. For instance, the interfaces hierarchy is focused on configuring specific interface settings, while the protocols hierarchy deals with routing and other protocol-specific configurations. The forwarding-options hierarchy contains configurations related to routing and forwarding behavior but does not specifically address Ethernet switching features like static bridge table entries.
