The Acterna DA-380, also known as the Domino GB Internetwork Analyzer, is a portable Gigabit Ethernet protocol analyzer engineered for real-time troubleshooting and performance validation of high-speed backbone networks. It combines full line-rate packet capture with intelligent traffic generation and multi-segment analysis capabilities to isolate and resolve internetwork problems across complex routing and switching infrastructures.
Technical Specifications
Capture and Processing
• 128 Mbytes capture buffer
• 32 ns timestamp resolution
• Full line-rate, full-duplex capture on dedicated receive and transmit channels
• Eight 112-byte pattern-matching filters with user-configurable triggers
• Pre-capture frame slicing isolates payload data for extended capture depth
• Multiple parallel RISC processors decode traffic and compute network statistics
Protocol Analysis
• Identifies over 1000 protocols with over 400 decode types
• Supports 802.1p and 802.1q tagging
• Filters on MAC, IP, and IPX criteria (LLC, 802.3, SNAP)
• Error detection and filtering for runts, jabbers, and CRC errors
• Auto-negotiation link configuration status decoding
Traffic Generation
• Transmits at up to 100% line rate
• User-defined frame creation or replay from captured frames
• Configurable interframe gap at 20 ns intervals, starting at 40 ns
Analysis and Reporting
• Over 100 statistics and graphs including network utilization, protocol distribution, frame rate, and frame size distribution
• Top station talker identification
• Full-color customizable display output
– Key Features
