Wim Router Features - Samsung OFFICESERV OfficeServ 7200 General Description Manual

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 LIM.
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 corresponding
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 WIM ROUTER FEATURES

Multiple Network Interfaces
The OfficeServ 7200 provides WAN1 and WAN2 network connections, which are connected to the WAN
through an Ethernet interface. The WIM also provides a V.35 serial WAN interface along with LAN and DMZ
network interfaces.
Static Routing
The OfficeServ 7200 configures a fixed routing table between each network interface to process the static
routing. In this case, the routing table cannot be dynamically changed by routing protocols. Specific routing
services will be provided according to the pre-set routing policy.
WAN Interface (Ethernet, PPPoE, DHCP Client)
The OfficeServ 7200 accesses the Internet through the WAN1 and WAN2 Ethernet WAN interface by using the
PPPoE and DHCP client protocols.
V.35 Interface (PPP, HDLC, Frame Relay)
The OfficeServ 7200 can also access the Internet through the V.35 serial interface with a transfer speed of up
to 2Mbps. In this case, the OfficeServ 7200 supports various protocols such as the PPP, HDLC, and Frame Relay
Encapsulation.
