Capture Mode
The mode in which Surveyor receives network data and stores it in the Capture
Buffer.
Capture View
A window for viewing and decoding network packets saved to a file or in the cap-
ture buffer.
Captured Frames
Frames stored within Surveyor’s capture buffer.
Century 12-Tap
A fault-tolerant wiring device, available from Finisar, that can be inserted into
twelve, full-duplex or half-duplex, 10 or 100 Mbps Ethernet links. Century 12-Tap
provides the ability to view up to twelve full-duplex segments from a single Sur-
veyor installation.
Collision
A counter that shows the best estimate of the total number of collisions (packets
arriving at exactly the same time) on this Ethernet segment. Transmit collisions are
not counted.
CRC/Align Error
A counter that shows the total number of packets received that had a length between
64 and 1518 octets, inclusive, but had either a bad FCS with an integral number of
octets (FCS/CRC Error) or a bad FCS with a non-integral number of octets (Align-
ment Error).
CRC Errors
Cyclical Redundancy Check (CRC) errors.
DA
Destination address. MAC level station address of where a frame is sent.
Deactivated Stream
A defined packet or set of packets defined in a transmit specification but not cur-
rently active. Deactivated streams are NOT loaded to a module for transmission.
Defined Stream
In transmission mode, a sequence of bytes you specify for transmission on the net-
work. Multiple streams can be defined for transmission.
