Configuration Management; Quality Of Service - Nortel BayStack 460-24T-PWR Product Brief

On-box management
Network management begins with the device. The BayStack 460 Switch supports four
groups of Remote Monitoring (RMON) on all ports and is SNMPv3 compliant. The four
groups 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
resides in the switch and uses the information it collects to provide management for all
ports in the stack providing comprehensive network monitoring capabilities. In addition,
the agent also provides the ability to set up policy-based networks by supporting the
Common Open Policy Support (COPS) protocol.

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. Optivity Switch Manager
(OSM) 4.0 is a Java-based, real-time, configuration management application for Nortel
Networks Ethernet products including the BayStack 460 Switch. 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 Optivity Network Management System (ONMS), the network manager has quick
access to the information required to manage and isolate all network events on BayStack
460 Switches. Tools, such as Physical Topology View, inform the network manager how a
particular event is affecting the physical connectivity within the network. The 'End Node
Locate' tool provides the ability to locate a failing end node and, with one mouse click,
have access to the RMON statistics for the failing Ethernet port supporting that end
node. These solutions provide visual and statistical tools necessary to quickly resolve any
network event or to manage performance in real-time. The BayStack 460 Switches
support "syslog" capability that helps in troubleshooting network issues.

Quality of Service

The BayStack 460 Switch's QoS features allow you to not just utilize bandwidth more effi-
ciently, optimizing existing network resources and capabilities, but also provide packet
classification and marking at the edge of the network, simplifying the QoS deployment at
the aggregation and core of the network. By classifying, prioritizing, policing, and
marking (DiffServ Code Point) LAN traffic, networks can offer reliable connectivity and
required bandwidth for mission-critical applications like IP Telephony and mission-critical
data applications to specific groups and users, and to individual devices.
For each of these applications, advanced QoS features support Internet Engineering Task
Force (IETF) standard DiffServ QoS architecture—a packet classification based on the
content of IP packet header fields (voice, video, data), traffic policing, and remote sniffing.
Queuing function
BayStack 460 Switch provides network availability for mission-critical applications,
devices, and users. This is performed by classifying, prioritizing, and marking LAN IP
traffic using up to eight hardware-based queues on every port, including the stacking ports
based on the following parameters:
• MAC address-based filtering
• IP ToS/DSCP marking
