ASCII configuration file
BayStack 5520 Switches can download a user-editable ASCII configuration file from a
TFTP (Trivial File Transfer Protocol) server. The ASCII configuration file can be loaded
automatically at boot time or on demand using the management systems (console menus or
CLI). Once downloaded, the configuration file automatically configures the switch or stack
according to the NNCLI commands in the file. This feature provides administrators with
the flexibility of creating command configuration files that can be used on several switches
or stacks with minor modifications.
ASCII configuration generator
The configuration settings of the switch can be displayed or saved to an external ASCII
configuration file made up of a series of CLI commands. This editable ASCII configuration
file can then be uploaded to a switch from an external file server. The ASCII configuration
file contains configuration settings for the following network management applications:
• Core applications (system information, topology, etc.)
• Internet Protocol
• Multi-Link Trunking (MLT)
• Port configuration
• Partial Spanning Tree configuration, including configuration of port priority and path cost
• VLAN configuration
• Quality of Service (QoS)
• RMON
Custom Auto-negotiation Advertisements
This feature enables the network manager to tune the capabilities that a particular Ethernet
port can advertise via auto-negotiation. The capabilities include half-duplex and full-duplex
modes with speeds of 10, 100, and 1000 Mbps. Auto-negotiated Ethernet ports establish a
connection based upon the highest common capabilities. This feature saves the network
manager from having to go to each workstation and switch to configure a "fixed" speed.
Customizable Queue/Buffer Allocation
Using this feature, the network administrator is able to specify the number of CoS queues
supported and the buffering resources that may be consumed by a given port. It allows the
network administrator to tune the use of system resources based upon their business needs.
Auto MDI/MDIX
BayStack 5520 Switches can be connected to a hub or another switch quickly and cost
effectively with either a crossover or straight through cable. When a cable is connected to
one of the 10/100/1000 ports on the switch, the switch port automatically detects the
energy on the cable and configures itself. This feature eliminates the need for an
MDI/MDIX port; any port may be used for connection to a hub or switch.
Common look and feel
All BayStack switches, including the BayStack 5520, have a common "look and feel"
which reduces training costs. This allows the switches to be managed in a similar fashion
via a broad set of management tools. These tools include Web, Java™-based Device
Manager (JDM), Command Line Interface (CLI), menus, Optivity Network Management
System (ONMS), Optivity Switch Manager (OSM), and Optivity Policy Services (OPS).
Web-based management
Web-based network management makes managing the BayStack 5520 Switch stack easy
with a Web browser. Summary, configuration, fault, statistics, application, administration,
and support pages can be provided for the entire stack. Traffic classification and prioritiza-
tion 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.
