Page 248: Virtual Local Area Networks (Vlans)
GS748T Smart Switch Software Administration Manual Virtual Local Area Networks (VLANs) A local area network (LAN) can generally be defined as a broadcast domain. Hubs, bridges, or switches in the same physical segment or segments connect all end node devices. End nodes can communicate with each other without the need for a router.
Page 249: Vlan Example Configuration
GS748T Smart Switch Software Administration Manual • Packets leaving the switch are either tagged or untagged, depending on the setting for that port’s VLAN membership properties. A U for a given port means that packets leaving the switch from that port are untagged. Inversely, a T for a given port means that packets leaving the switch from that port are tagged with the VLAN ID that is associated with the port.
Page 250: Access Control Lists (Acls)
GS748T Smart Switch Software Administration Manual Access Control Lists (ACLs) ACLs ensure that only authorized users have access to specific resources while blocking off any unwarranted attempts to reach network resources. ACLs are used to provide traffic flow control, restrict contents of routing updates, decide which types of traffic are forwarded or blocked, and provide security for the network.

Page 253: Differentiated Services (Diffserv)
GS748T Smart Switch Software Administration Manual Differentiated Services (DiffServ) Standard IP-based networks are designed to provide best effort data delivery service. Best effort service implies that the network deliver the data in a timely fashion, although there is no guarantee that it will. During times of congestion, packets may be delayed, sent sporadically, or dropped.
Page 254: Diffserv Traffic Classes

GS748T Smart Switch Software Administration Manual 802.1X Local Area Networks (LANs) are often deployed in environments that permit unauthorized devices to be physically attached to the LAN infrastructure, or permit unauthorized users to attempt to access the LAN through equipment already attached. In such environments, it may be desirable to restrict access to the services offered by the LAN to those users and devices that are permitted to use those services.
