Overview of MAC Address Management

The switch assigns MAC addresses in these areas:

For management functions, one Base MAC address is assigned to the default VLAN (VID = 1). (All VLANs on the switches covered in this guide use the same MAC address.)
For internal switch operations: One MAC address per port (see Viewing the port and VLAN MAC addresses.

MAC addresses are assigned at the factory. The switch automatically implements these addresses for VLANs and ports as they are added to the switch.

NOTE:

The switch’s base MAC address is also printed on a label affixed to the switch.
