IEEE 802.1p Prioritizing

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

For more information about the 802.1p prioritizing feature, see “ IEEE 802.1p Prioritizing” on page 1-53.

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 “ IEEE 802.1Q VLAN Workgroups” on page 1-32.
