Navigating Local Management Screens

1.1.2In-Band vs. Out-of-Band

Network management systems are often classified as either in-band or out-of-band. In-band network management passes data along the same medium (cables, frequencies) used by all other stations on the network.

Out-of-band network management passes data along a medium that is entirely separate from the common data carrier of the network, for example, a cable connection between a dumb terminal and

aSmartSwitch device COM port. The Enterasys Networks’ Local Management is an out-of-band network management system.

A device connected out-of-band to the management agent is not connected to the LAN. This type of connection allows you to communicate with a network device even when that device is unable to communicate through the network, for example, at the time of installation.

1.2NAVIGATING LOCAL MANAGEMENT SCREENS

To navigate within a Local Management screen, use the arrow keys of the terminal or the workstation providing terminal emulation services. The Local Management screen cursor responds to the LEFT, RIGHT, UP, and DOWN arrow keys. Each time you press an arrow key, the Local Management screen cursor moves to the next available field in the direction of the arrow key.

The Local Management screen cursor only moves to fields that can be selected or used for input. This means that the cursor jumps over display fields and empty lines on the Local Management screen.

The Local Management screen cursor provides wrap-around operation. This means that a cursor located at the edge of a screen, when moved in the direction of that edge, “wraps around” to the outermost selectable item on the opposite side of the screen which is on the same line or column.

1.3LOCAL MANAGEMENT REQUIREMENTS

The SmartSwitch device provides one communication port, labeled COM, which supports a management terminal connection. To access Local Management, connect one of the following systems to the COM port:

•Digital Equipment Corporation VT series terminal.

•VT type terminal running emulation programs for the Digital Equipment Corporation VT series.

•IBM or compatible PC running a VT series emulation software package.
