Introduction
MAC Address
The physical layer address assigned to the interface associated with the IP address
used to deÞne the device icon when it was added to SPECTRUM Element
Manager. MAC addresses are hard-coded in the device, and are not conÞgurable.
Informational Þelds describing the boards and/or ports being modeled are also
displayed in most windows:
Board Number
Displays the number indicating the position of the monitored board in the chassis.
Port Number
Displays the number of the monitored port.
Active Users
Indicates the number of users processing information through the deviceÕs
repeater channel, board, or port, as determined by MAC addresses.
Uptime
Displays the amount of time, in a days hh:mm:ss format, that the device has been
running since the last start-up.
Using Window Buttons
The Cancel button that appears at the bottom of most windows allows you to exit
a window and terminate any unsaved changes you have made. You may also
have to use this button to close a window after you have made any necessary
changes and set them by clicking on the OK, Set, or Apply button.
An OK, Set, or Apply button appears in windows that have conÞgurable values;
it allows you to conÞrm and SET changes you have made to those values. In some
windows, you may have to use this button to conÞrm each individual set; in other
windows, you can set several values at once and conÞrm the sets with one click
on the button.
The Help button brings up a Help text box with information speciÞc to the
current window. For more information on the Help button, see Using On-line
Help, page 1-8.
The command buttons, for example Bridge, call up a menu listing the windows,
screens, or commands available for that topic.
Any menu topic followed by ... (three dots) Ñ for example Statistics... Ñ calls up
a window or screen associated with that topic.
