SmartBits System Reference 257
ET-1000 functions
Based on the ET-1000 controller, the grandfather of the SmartBits chassis, certain ET-
functions were used with 10Mbps Ethernet cards and available in SmartWindow and
SmartLib. Now obsolete, these functions are only available if you have older applications
and chassis firmware version lower than Version 6.60.
fill pattern
Also known as the Background. In SmartWindow, displays the pattern template to be used
for the frame. To edit a template, select the pattern from the drop down list and click the
Edit button. The Frame Editor is displayed.
Frame Editor
See also Protocol Editor.
The Frame Editor window provides a template to directly control required IP header fields
for native IP traffic generation over Ethernet, Token Ring, and ATM. You can edit
background frame content or create custom background test frames as a means to enter a
protocol into a frame.
Important: The last 18 bytes of each SmartMetrics mode stream is Reserved for Smart-
Bits usage. Any values inserted into a custom packet in the last 18 bytes will be over-
written by the SmartMetrics signature data.
GBIC
Copper gigabit interface converter. GBIC is an industry standard interface that allows
users to change the physical interface to support either multi-mode or single-mode fiber.
grouping ports
The concept of Group allows multiple SmartCards to be configured at the same time and
set up for simultaneous transmission and testing.
For a card to be part of a group, it must be owned:
• Implicit Ownership–Occurs with single-user chassis. Since only one user can
connect to a single user chassis, all cards are considered to be owned when you make
the connection.
• Explicit Ownership–Occurs with multi-user chassis. More than one user can connect
to the same chassis. When a connection is made, the user must reserve the desired
cards. No other user can own these cards.
Ownership is indicated visually by color-coded triangular LEDs next to the port ID
number, or by color-coded button LEDs next to the port IDs in a reservations listing:
Blue triangle LED – card is reserved to you.
Green triangle LED – card is available.
