SPEEDLAN 8500 Series Installation and Operation User Guide
1-4 Introduction
allows network administrators to assign dynamic IP addresses for the period of time needed to
connect to the Internet or network, whereas static IP addresses are beneficial to users that need to
maintain a "constant" connection. This reduces the load on the entire wireless network.
Transparent Ethernet Bridging with Advanced Filtering for Security and
Network Reliability
SPEEDLAN 8500 products support what is known as Transparent Ethernet Bridging with no Spanning
Tree or Source Routing support. Since the SPEEDLAN 8500 IDUs provide network security between a
local LAN and a campus or enterprise wide network, and since using multiple IDUs in a Spanning
Tree could compromise this security, the Spanning Tree scenario is not supported. In addition, the
SPEEDLAN 8500 IDUs can filter packets based on protocol type or MAC address pairings. These
features can add a significant measure of security and network reliability to a network
interconnection.
IP Routing with Advanced Filtering for Security
The SPEEDLAN 8500 IDUs support IP Routing in addition to bridging. It can be used to add routing
capability when an IP router may be a more appropriate choice.
Wireless Multipoint Protocol
SectorPRC features provide multipoint networking, improved performance, and increased reliability.
In multipoint networks, the IDU central base station manages the flow of data within the radio cell.
When necessary, packets are repeated or retransmitted by this IDU, allowing communications
between multiple remote networks by using the IDU CPE.
SNMP Management
SNMP wireless and wired link management may be administered from any Ethernet network or
remotely from the Internet. The SNMP MIB II, IDU MIB, and Ethernet-Interface MIB come with the
IDUs, so you can use SNMP to monitor a number of SPEEDLAN 8500 parameters, including RF-
signal quality and noise level.
