Transmit Characteristics:
– Full line rate: (100 Mbps) transmit.
– Duplex operation: full
– Frame length: 24-1, 600 bytes (without FCS), random (L2 mode only).
– Interpacket gap: 100 Mbps = min. 960 nsec, max. 2.68 seconds; or random (L2
mode only).
– Background frame data fill pattern: user-specified or random.
– Error generation: CRC, dribble bt, alignment, symbols (100 Mbps mode only),
data integrity (per stream; L3 mode only).
– Error detection: CRC, alignment, oversize, udnersize, dribble, data integrity.
– VFD 1, VFD 2: up to 6 bytes, anywhere in a packet; static, increment, decrement,
random. Cycle: max. 4 billion; increment and decrement modes only. Stutter:
max. 4 billion; increment and decerment modes only.
– VFD 3: 2K byte buffer.
•
Stream-based Transmit Mode:
– Up to 1,000 streams per port.
– Up to 64K flows on each stream via IP source or destination addresses. Ability to
vary MAC address simultaneously with IP address.
•
Frame-based Transmit Mode:
– Constant frame transmit.
– Single burst, up to 4 billion packets in a single burst.
– Multi-burst, up to 4 billion repetitive bursts with user-defined delay between
bursts.
– Continuous Multi-burst.
•
Management Frame Transmit:
– Configures the modules MAC and IP address, Netmask, and Gateway.
– User-selectable Ping, SNMP, and RIP frequency.
– Ability to reply to ARP requests.
•
Capture:
– Full line rate (100 Mbps) capture and analysis.
– Frame length: 18–2,006 bytes.
– Frame selection: entire frame only.
– 6500 frame capture buffer for frames.
– Pre-capture filtering on: CRC errors, undersize, oversize, data integrity errors,
alignment errors, received triggers, or all.
