24.9.2 MAC addresses of VLAN interfaces

VLAN interfaces for which an IP address is set use one of the MAC addresses of the Switch as the MAC address of the interface. The MAC addresses used are as follows:

• Switch MAC address

• MAC addresses for each VLAN

By default, the device MAC address is used, but can be set by configuration to the MAC address for each VLAN.

The MAC address for a VLAN interface can be changed during operation by configuration. Keep in mind that when the address is changed during operation, because the MAC addresses learned through ARP or NDP by the neighboring Layer 3 switches (routers, Layer 3 switches, or terminals) no longer match the MAC address of the Switch, communication might not be possible temporarily.
