Defining Reserved MAC Addresses
When the switch receives a frame using a Destination MAC address that belongs
to a reserved range (per the IEEE standard), the frame can be discarded or
bridged. The configuration can be set either by reserved MAC address or by
reserved MAC address and frame type, as follows:
• Reserved MAC address, frame type and Ethertype for EthertnetV2 frame
type
• Reserved MAC address, frame type and DSAP-SSAP for LLC frame type
• Reserved MAC address, frame type and PID for LLC-SNAP frame type
To configure an entry for a reserved MAC address:
