Glossary

VPPA:

Virtual PPA or VPPA: Virtual Interfaces which are dynamically created by you (using lanadmin or SAM). The interfaces are “virtual” because they do not have a unique hardware instance. A virtual PPA is the PPA associated with a VLAN.

VLAN: Virtual LAN.VLANs, are a mechanism to determine which end stations should receive broadcast traffic, since it should not be sent arbitrarily to every connected user. Each packet transmitted by an end-station is assigned to a VLAN. An end-station only receives all the multicast and broadcast traffic on the LANs to which it belongs, and an end-station receives unicast traffic addressed to it on the VLAN to which it belongs.

VLAN-aware:Devices such as switches and end-stations that can recognize VLAN tags, but they do not actually interpret them. See also tag-aware.

VLAN ID: A VLAN ID uniquely identifies the VLAN to which a frame belongs.

VLAN tag: A 4-byte extension to the MAC header consisting of a 2-byte VLAN protocol ID (0x8100) and 2-bytes of tag control information. VLAN tags enable traffic from more than one VLAN to use the same port.
