ACCESSING MANAGEMENT FEATURES

The menu-driven user interface built into the device is known as the VT100 or Local Management interface. The VT100 management interface has a forms-based structure with pre-defined security levels, enabling access to be restricted to particular users.

Accessing and navigating the local screens is described in the manual which accompanies your IBM 8271 Nways Ethernet LAN switch.

Screen Map

Figure 7-1 on page 7-2 provides a map of available local management screens. The screens shaded gray appear when the ATM Module is installed. If these screens do not appear, your ATM Module is not installed correctly.

Keyboard Shortcuts

There are several special characters or combinations of keyboard characters that allow you to navigate within the screens.

[Ctrl] + [K] displays a list of the available key strokes.

Correcting Text Entry

Use [Delete] on a VT100 terminal or [Backspace] on a PC. This moves the cursor one space to the left and deletes a character.

If you are using Telnet or a terminal emulation program you may find that some of the Control keys do not operate or that they activate other functions. Check carefully in the manual accompanying your Telnet or terminal emulation software before using the Control keys.
