Which CLI command removes a dynamically learned MAC address from the MAC table? Exam Dumps 51/115

The command clear mac-address-table dynamic is used in ArubaOS-CX to remove all dynamically learned MAC address entries from the forwarding database (MAC table). This action forces the switch to relearn the MAC addresses of connected devices as they transmit frames. This is a standard administrative procedure for troubleshooting Layer 2 connectivity issues or clearing stale entries after network topology changes. The dynamic keyword specifically targets entries learned through traffic observation, leaving any statically configured MAC addresses untouched.

B. The verb delete and the object name mac-table are not the correct syntax for this operation in the ArubaOS-CX command-line interface.

C. The verb flush is not used for clearing the MAC address table in ArubaOS-CX; the correct command verb is clear.

D. The correct object name is mac-address-table, not mac-table. This command is syntactically incorrect and would not be recognized by the switch.
