Network Management; Configuration Management - Nortel BayStack 325-24G Specifications

IEEE 802.1p priority queuing
802.1p priority queuing is standards-based and enables priority to the order in which the
switch forwards packets, on a per-port basis. For example, if messages from a specific segment
are crucial to the network, the switch port connected to that segment can be set to a higher
priority level. Up to four queues can be set on a BayStack 325 Switch with IEEE 802.1p.
Supports Spanning Tree protocol
Built-in support for Spanning Tree protocol (IEEE 802.1D) detects and eliminates logical
loops in the network. When multiple paths exist, the switch will automatically place some
ports on standby to form a network with the most efficient traffic pathways, avoiding the
continual looping of frames.
Custom Auto Negotiation Advertisements (CANA)
This feature enables the network manager to tune the capabilities that a particular Ethernet
port can advertise via autonegotiation. The capabilities include half-duplex and full-duplex
modes with speeds of 10, 100, and 1000 Mbps. Autonegotiated Ethernet ports establish a
connection based upon the highest common capabilities. This feature is implemented by
using CLI commands and saves the network manager from having to go to each work-
station and switch to configure a "fixed" speed.

Network management

Web-based management
Web-based network management makes managing BayStack 325 Switches easy with a Web
browser. Summary, configuration, fault, statistics, application, administration, and support
pages 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 management
Network management begins with the device. BayStack 325 Switches support four groups
of Remote Monitoring (RMON) on all ports and are SNMPv3 compliant. The four groups
of RMON are Alarms, Events, History, and Statistics. RMON2 support is achievable via
port mirroring and the use of an external probe. The SNMP agent software resides in the
switch and uses the information it collects to provide management for all ports providing
comprehensive network monitoring capabilities.

Configuration management

The 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 require
communicating with a single device. It uses a common user interface and workflow that
supports many Nortel Networks Ethernet switches. This commonality allows the network
manager to become familiar with one tool instead of multiple tools. Nortel Networks
Optivity* Switch Manager † (OSM) is a Java-based, real-time, configuration management
application for Nortel Networks Ethernet products, including BayStack 325 Switches. It
enables network managers to discover, view, and configure more than 500 network devices
and their physical links on a topology map. Configuration is stored in NVRAM (Non-Volatile
Random Access Memory).
Fault management and resolution
With Nortel Networks Optivity Network Management System † (ONMS), the network
manager has quick access to the information required to manage and isolate all network
events on BayStack 325 switches. Tools, such as Physical Topology View, inform the network
