Network management
On-Box management
Network management begins with the device. BayStack 5520 Switches support four groups of
Remote Monitoring (RMON) on all ports and are SNMPv3 compliant. 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
in the stack 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 commu-
nicating 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) † is
another tool that performs the configuration function such as VLAN assignments, MLT, and
Multicast across multiple Nortel Networks Ethernet switches.
Policy-management
Optivity Policy Services —a suite of policy-management software that enforces business-
†
level policies automatically across the network—now supports BayStack 5520 Switches.
OPS supports network managers by providing centralized control of advanced packet
classification and the ability to priority mark, police, meter, or block traffic.
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
5520 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,
provide 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 5520 Switches
support "syslog" capability that helps in troubleshooting network issues.
Port mirroring
The port mirroring feature (sometimes referred to as 'conversation steering') allows the
network administrator to designate a single switch port as a traffic monitor for a specified
port. Port-based monitoring can be specified for ingress and egress at a specific port. MAC
address-based mirroring can also be specified. Additionally, an external probe device can be
attached to the designated monitor port.
User Interface push-button
The User Interface push-button on the front panel is provided for ease of use in configur-
ing the unit. It can be used for the purpose of base unit selection and for resetting the
unit or the stack.
LED indicators
The LED indicators on the front panel make it easy to monitor the switch status and help
in isolating and diagnosing switch problems. These indicators include "Power," "Base unit,"
"Up" and "Down," "RPSU," "Speed/Duplex/PoE," and "LNK/ACT" functions.
