-- MAC address-based
• Configuration file download/upload support: allows you to store your switch/
stack configuration parameters on a TFTP server.

IEEE 802.1p Prioritizing

The BayStack 450 switch can prioritize the order in which packets are forwarded,
on a per-port basis.

IEEE 802.1Q VLANs

BayStack 450 switches support up to 64 port-based VLANs with IEEE 802.1Q
tagging available per port. When a switch port is configured to be a member of a
VLAN, it is added to a group of ports (workgroup) that belong to one broadcast
domain. You can assign different ports (and therefore the devices attached to these
ports) to different broadcast domains. This feature allows network flexibility
because you can reassign VLANs to accommodate network moves, additions, and
changes, eliminating the need to change physical cabling. For more information
about 802.1Q VLANs, see
