connection based upon the highest common capabilities. This feature is implementedby using CLI commands and saves the network manager from having to go to each work-station and switch to configure a "fixed" speed.Network managementWeb-based managementWeb-based network management makes managing the BayStack 425 Switch stack easy.Summary, configuration, fault, statistics, application, administration, and support pages canbe provided for the entire stack. Real-time sampling provides up-to-date LED statisticalinformation for stacked units. The Web interface also allows for static configuration ofnumerous parameters of the device. Plus, the stack can be managed as a single entity with oneIP address.On-box managementNetwork management begins with the device. BayStack 425 Switches support four groupsof Remote Monitoring (RMON) on all ports and are SNMPv3 compliant. The fourgroups of RMON are Alarms, Events, History, and Statistics. RMON2 support is achiev-able via port mirroring and the use of an external probe. The SNMP agent software residesin the switch and uses the information it collects to provide management for all ports in thestack providing comprehensive network monitoring capabilities.Configuration managementThe process of configuration begins with a single device but finishes across multipledevices. Java™ Device Manager is the device configuration tool for those functions thatrequire communicating with a single device. It uses a common user interface and workflowthat supports many Nortel Networks Ethernet switches. This commonality allows thenetwork manager to become familiar with one tool instead of multiple tools. OptivitySwitch Manager* (OSM) is a Java-based, real-time, configuration management applicationfor Nortel Networks Ethernet products including BayStack 425 Switches. It enablesnetwork managers to discover, view, and configure more than 500 network devices andtheir physical links on a topology map. Configuration is stored in NVRAM (Non-VolatileRandom Access Memory).Fault management and resolutionWith Optivity Network Management System(ONMS), the network manager has quick accessto the information required to manage andisolate all network events on BayStack 425switches. Tools, such as Physical Topology View,inform the network manager of how a particularevent is affecting the physical connectivitywithin the network. The ‘End Node Locate’ toolprovides the ability to locate a failing end nodeand, with one mouse click, provides access tothe RMON statistics for the failing Ethernetport supporting that end node. These solutionsprovide visual and statistical tools necessary toquickly resolve network events or to manageperformance in real-time. The BayStack 425Switches support “syslog” capability that helpsin troubleshooting network issues.5Figure 6.
