PART 5. DATA MODULE FEATURES
With the LIM, PLIM, PLIM2, and GPLIMT data modules, the OfficeServ 7200-S functions as a data router, data
switch, performs security functions, and serves as a data access interface.

5.1 PLIM/PLIM2 FEATURES

Using the PLIM/PLIM2 as an Unmanaged Switch
The PLIM/PLIM2 performs the function of a layer 2 Ethernet switch as well as the Learning Bridge function
based on the MAC address filtering and forwarding algorithm.
The PLIM/PLIM2 provides 16 LAN ports per card. Each port is 10/100 Base T, auto sensing, full duplex.
802.1d Spanning Tree
The switch configures and processes the forwarding tree based on the spanning tree algorithm to prevent a
packet forwarding loop in the switch.
802.1p Packet Priority
The switch extracts the priority field from the Ethernet frame configured according to the 802.1p specifica-
tion standard, and discriminatively processes the frame according to the priority of the specified operation
standard.
The packets are categorized into emergent packets and non-emergent packets and are then processed.
VLAN
Virtual Local Area Network(VLAN) groups can be created to separate and group the physical ports of the
PLIM/PLIM2. Each VLAN group can be treated as if they were each a separate private LAN. The VLAN removes
the effects of unnecessary broadcast packets and configures a stable switching subnet only for the corre-
sponding group by separating and processing the group in the virtual LAN.
Accordingly, the switch can provide the differentiated QoS services. The VLAN can be configured based on
the switch port and MAC address.
IGMP Snooping
IGMP Snooping provides a method for intelligent forwarding of multicast packets within a layer 2 broadcast
domain. By snooping IGMP registration information, a distribution list of work stations is formed that deter-
mines which end-stations will receive packets with a specific multicast address.

5.2 PLIM2

The PLIM2 is an unmanaged layer 2 LAN switch. It provides 16 10/100 Base-T Ethernet interfaces and supports
Power over Ethernet (IEEE 802.3af ). Each Ethernet port is auto sensing and full duplex.
