CHAPTER 4. OfficeServ 7400 Functions
802.1x Supported
IEEE 802.1x standards define the formats and the operational procedures of EAP over
LAN (EAPoL) frame that can send/receive the Extensible Authentication Protocol (EAP)
between terminals and the Access Point (AP). These standards are called the port security
protocol because they can be used in the procedure permitting network access by the termi-
nal only by acquiring the physical port license of the Bridge or wireless AP from the au-
thentication server. This authentication procedure by ports enables control of charging poli-
cies, usage restriction, band allocation, etc, separately.
Port Trunking Function Supported
Port Trunking means Port Aggregation, the collection of physical ports into logical ones.
That is, like the 100 BASE-TX securing 100Mbps bandwidth, the function collects several
ports into a logical port for expanding the bandwidth to be used.
PoE (IEEE 802.3af) Function Supported
Power over Ethernet (PoE) is designed so that no additional power supply to network
equipment used in wireless or wired LAN is necessary. PoE allows the user to send the
data and the power simultaneously via an Ethernet cable, thus reducing the installation cost
in most cases and providing high flexibility in selecting the installation site for the equip-
ment.
QoS Function Supported
OfficeServ 7400 provides the 802.1p Packet Priority and Level Classification Setup for
supporting Quality of Service (QoS). The 802.1p Packet Priority is the expansion of the
standard MAC header in the network packet. This expansion provides the packets with pri-
ority: a packet of higher priority is treated preferentially and is processed ahead of a packet
of lower priority. The Level Classification Setup function gives the packets High/Low lev-
els and processes them according to these levels, thus making the differential services pos-
sible.
GARP/GVRP Function Supported
Generic Attribute Registration Protocol (GARP)/Generic VLAN Registration Proto-
col (GVRP) define a GARP application that provides the 802.1Q-compliant VLAN prun-
ing and dynamic VLAN creation on 802.1Q trunk ports. GVRP is an application defined in
the IEEE 802.1P standard that allows for the control of 802.1Q VLANs.
