Network Access

By default, for how long will the switch continue to retain a workstation MAC address after the workstation stops sending traffic?

  • A 200 seconds
  • B 300 seconds
  • C 600 seconds
  • D 900 seconds
Explanation

A switch keeps dynamically learned MAC addresses in its MAC address table until the MAC aging timer expires. The default aging time is typically 300 seconds, so if the workstation stops transmitting and no new frames refresh the entry, the switch will continue to know that MAC address for 5 minutes before removing it.
