Hi,

On CRS226-24G-2s+ with v6.40.5 (and not only) I'm using MAC Based VLAN. There are relatively many devices not accepted by the switch: the mac address is marked in red and doesn't work. For computers I can change the mac address of the internet card, but for different network devices is impossible therefore they are useless on the network. Is there any workaround to fix this problem? Sometimes a MAC is rejected on a switch but accepted on another with the same firmware version.

Thanks in advance,
chrysmon

This is a hardware limitation, this has also been added to the wiki:
