IP Manager List limits access to the management features of the BayStack 460 Switch by a defined list of IP addresses or IP address ranges/subnets, providing greater network security and manageability.

BaySecure* MAC-address based security allows authentication of all access, not only to the switches for management and config- urations, but also access to the infrastructure through these switches. This software feature limits access to only network authorized and trusted personnel, including full tracking of network connections. With BaySecure, network access is granted or denied via proper MAC-address identification (up to a maximum of 448).

The RADIUS-based security feature allows you to set up network access control to authenticate local console and Telnet logins.

Power sharing options

The BayStack 460 Switch can be used in conjunction with the BayStack 10 PSU or NES (Network Energy Source) DC Power System from Invensys (www.intergynes.com) to create a load sharing, RPSU, or UPS solution.

Load sharing

The BayStack 460 Switch provides up to 200 watts to power the devices. With the addition of a BayStack 10 PSU, up to 235 watts of total power can be supplied to devices. A 2-pin cable is required to connect from the BayStack 460 to the BayStack 10 PSU (AL2018008). With the addition of NES DC power system, up to 370 watts of total power can be supplied to devices.

Redundant power supply unit support

Using a BayStack 10 PSU will provide up to 75 watts of power to be supplied to devices in case the power supply of the BayStack 460 fails. A 2-pin cable is required

to connect from the BayStack 460 to the BayStack 10 PSU (AL2018008). Using NES DC power system, up to 200 watts of power can be supplied to devices in case the power supply of the BayStack 460 fails.

Uninterruptible power supply support

Using a BayStack 10 PSU will provide up to 75 watts of power to be supplied to devices in case there is an electrical outage. Up to 15 minutes of battery life is provided (this will vary depending on the amount of modules installed on the BayStack 10). Using NES DC power system, up to 200 watts of power can be supplied to devices in case there is an electrical outage. With NES system, up to 8 hours of battery life is provided (this will vary depending on the amount of modules on the NES unit).

Network management

Web-based management

Web-based network management makes managing the BayStack 460 Switch stack easy with a Web browser. Summary, config- uration, fault, statistics, application, administration, and support pages can be provided for the entire stack. Traffic classification and prioritization can be set via the Web-based QoS Wizard and advanced configuration tool. Real-time sampling provides up-to-date LED statistical information for stacked units. The Web interface also allows for static configuration of numerous parameters of the device. Plus, the stack can be managed as a single entity with one IP address.

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 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. 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) performs the configuration function such as VLAN assignments, MLT, and multicast across multiple Nortel Networks Ethernet switches. 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
