Which command will allow an administrator to view which MAC addresses are mapped to which ports on a Cisco Catalyst switch?

  • show address-table
  • show mac address-table
  • show mac-address table
  • show address table

Explanation: The show mac address-table command is the standard diagnostic tool used to display the contents of the Content-Addressable Memory (CAM) table on a Cisco Catalyst switch. This table is fundamental to Layer 2 operation, as it maps learned source MAC addresses to the specific physical ports and VLANs where they were detected. When a switch receives a frame, it records the source address and the inbound port to build this forwarding database, allowing it to forward subsequent traffic to the correct destination rather than flooding it out of all ports. By executing this command in privileged EXEC mode, an administrator can effectively verify device connectivity, troubleshoot VLAN assignment errors, and monitor how the switch is dynamically learning about the attached network environment. Additionally, the command allows for specific views, such as filtering by a particular interface or VLAN, which is essential for isolating connectivity issues in complex campus designs.
