3560CX Series MAC Address Handling/Blocking

[mac_interp]

I intend to use this switch in a LAN with custom devices that have unusual MAC addresses. The least significant bits of the first byte are 11, and the EUI-48 specification indicates that some network devices will interpret these bits as multicast and locally administered. Will this switch block a MAC address that indicates it is multicast?

"The default is to not block flooding of unknown multicast and unicast traffic out of a port, but to flood these packets to all ports."
