• Port Overlapping - You can use port overlapping to allow access to commonly
shared network resources among different VLAN groups, such as file servers or
printers.
• Untagged VLANs - Untagged (or static) VLANs are typically used to reduce
broadcast traffic and to increase security. A group of network users assigned to a
VLAN form a broadcast domain that is separate from other VLANs configured on
the LB52xA-KIT. Packets are forwarded only between ports that are designated
for the same VLAN. Untagged VLANs can be used to manually isolate user
groups or subnets.
• Port VID (PVID) - A PVID is a VLAN ID assigned to untagged frames received
on the interface. (Default: 1). If an interface is not a member of VLAN 1 and you
assign its PVID to this VLAN, the interface will automatically be added to VLAN 1
as an untagged member. For all other VLANs, an interface must first be config-
ured as an untagged member before you can assign its PVID to that group.
• Link Type - The Link Type determines the types of frames the port can accept.
Access means the port can only receive or send untagged frame types. Trunk
means that the port can only receive or send tagged frame types.
