IEEE 802.1p priority queuing802.1p priority queuing is standards-based and enables priority to the order in which theswitch forwards packets, on a per-port basis. For example, if messages from a specific segmentare crucial to the network, the switch port connected to that segment can be set to a higherpriority level. Up to four queues can be set on a BayStack 325 Switch with IEEE 802.1p.Supports Spanning Tree protocolBuilt-in support for Spanning Tree protocol (IEEE 802.1D) detects and eliminates logicalloops in the network. When multiple paths exist, the switch will automatically place someports on standby to form a network with the most efficient traffic pathways, avoiding thecontinual looping of frames.Custom Auto Negotiation Advertisements (CANA)This feature enables the network manager to tune the capabilities that a particular Ethernetport can advertise via autonegotiation. The capabilities include half-duplex and full-duplexmodes with speeds of 10, 100, and 1000 Mbps. Autonegotiated Ethernet ports establish aconnection based upon the highest common capabilities. This feature is implemented byusing 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 BayStack 325 Switches easy with a Webbrowser. Summary, configuration, fault, statistics, application, administration, and supportpages can be provided. Real-time sampling provides up-to-date LED statistical information.The Web interface also allows for static configuration of numerous parameters of the device.On-box managementNetwork management begins with the device. BayStack 325 Switches support four groupsof Remote Monitoring (RMON) on all ports and are SNMPv3 compliant. The four groupsof RMON are Alarms, Events, History, and Statistics. RMON2 support is achievable viaport mirroring and the use of an external probe. The SNMP agent software resides in theswitch and uses the information it collects to provide management for all ports providingcomprehensive network monitoring capabilities.Configuration managementThe process of configuration begins with a single device but finishes across multiple devices.Java™ Device Manager is the device configuration tool for those functions that requirecommunicating with a single device. It uses a common user interface and workflow thatsupports many Nortel Networks Ethernet switches. This commonality allows the networkmanager to become familiar with one tool instead of multiple tools. Nortel NetworksOptivity* Switch Manager † (OSM) is a Java-based, real-time, configuration managementapplication for Nortel Networks Ethernet products, including BayStack 325 Switches. Itenables network managers to discover, view, and configure more than 500 network devicesand their physical links on a topology map. Configuration is stored in NVRAM (Non-VolatileRandom Access Memory).Fault management and resolutionWith Nortel Networks Optivity Network Management System † (ONMS), the networkmanager has quick access to the information required to manage and isolate all networkevents on BayStack 325 switches. Tools, such as Physical Topology View, inform the network4
