USER’S GUIDE18 SmartSwitch Remote Access Moduletroubleshooting capabilities while the system is up and running. The modules also support SNMPwith both MIB II, private extensions, and a container MIB indicating the current configuration.ADDITIONAL SOFTWARECabletron also supplies two separate software products that are used in conjunction with theSmartSwitch Remote Access Modules: SFVRA Configuration Manager (SFVRA-CFG) and SFVRAConnection Manager (SFVRA-CONN).SFVRA-CFG provides a GUI interface for configuring the SmartSwitch Remote Access Module.Through the SFVRA-CFG, the network administrator can deploy and maintain an entireCyberSWITCH network through a centrally located device. The network administrator cangenerate each system’s configuration files separately, with the system’s view of the network, thentransfer the configuration files electronically to the system.SFVRA-CONN offers state of the art policy-based management system for large central site dial-innetworks. This software provides a rich set of network configuration, management, and reportingcapabilities. The functionality of SFVRA-CONN software includes policy-based connectivitymanagement, virtual networking that spans multiple modules (including multiple SmartSwitch9000 chassis, and even including multiple geographic sites) with audit/accounting capabilities.U NIQUE S YSTEM FEATURESThe SmartSwitch Remote Access Module combines unique features that improve cost-effectiveness, reliability, and performance for wide area network connections to remote devices.These features include:• Authentication ServersProvide a central database for networks with more than one SmartSwitch Remote AccessModule. The central database consists of manageable, informational data (referred to as theDevice List or Device Table). This data is accessed and used for authentication when a newconnection is established to the system.• Bandwidth AgilityThe system dynamically controls the bandwidth in use between itself and other PPP devices.This is accomplished by establishing and disconnecting calls. The number of calls is limitedonly by the types and number of lines available. The system monitors the connections forutilization and will add and remove the connections based on user-configurable throughputparameters. As network bandwidth requirements increase or decrease, the system willautomatically adjust the number of network connections. Thus, your network costs will reflectthe actual bandwidth being used.• Data CompressionAllows the system to negotiate compression algorithms with another device on the network.After successfully negotiating compression, data is compressed by the remote device andtransmitted to the system. The system decompresses the data, processes the informationcontained in the user data, and forwards the data as required. The system can receive datacoming over a WAN or a LAN, and compress the data before transmitting it to another deviceon the network. The net effect is to increase interconnect bandwidth by decreasingtransmission time. If negotiation for compression fails, data is transmitted uncompressed.
