The Agilent/Keysight E7922A is a 4-port 10/100 Ethernet routing test card engineered for comprehensive testing and validation of network devices in R&D and manufacturing environments. It generates and analyzes IP packets and Ethernet frames at line rate, supporting realistic testing of switches and routers with 10/100 interfaces. The module interoperates with other RouterTester variants (GbE and 10GbE) to construct scalable, Internet-scale test topologies.
Technical Specifications
Interfaces
• 4 × 10/100 Ethernet ports (10BASE-T/100BASE-TX)
• 256 MB data capture RAM per module with line-rate capture capability
• LAN, timing synchronization, trigger I/O, and BNC interfaces
Packet Generation and Analysis
• Simultaneous IPv4 and IPv6 packet generation and analysis for dual-stack router testing
• IEEE 802.1Q VLAN tagging support: up to 4095 VLAN IDs and 8 priority levels per port
• MAC layer addressing for layer 2 switch validation across configurable MAC address ranges
• Transmit, receive, and error statistics delivered in real-time tabular and graphical formats at IP, Link, and Physical layers
Routing and Network Emulation
• Emulates E-BGP, I-BGP, OSPF, IS-IS, and MPLS-TE routing protocols at line rate
• Large-scale route emulation with flexible attributes for forwarding table stress testing
• Route flap convergence measurement and data loss quantification during topology changes
Capture and Analysis
• Triggered data capture (manual, event-based, pattern-match, threshold, or error-condition driven)
• Protocol decoding: BGP-4, OSPF, IS-IS, and full Ethernet frame decode
• Per-port, per-stream, and per-VLAN-ID statistics for transmitted and received traffic
• Latency and packet loss measurement via synchronized packet timestamping
– Typical Applications
Route convergence testing, switch fabric validation, forwarding table capacity benchmarking, dual-stack IPv4/IPv6 interoperability validation, and VLAN configuration verification.
– Compatibility & Integration
Interoperates with RouterTester GbE and 10GbE modules to build modular, multi-port test systems.
