Several open-source tools are effective for generating high volumes of Address Resolution Protocol (ARP) requests to stress test network infrastructure, switches, and security devices.
TRex Network Traffic Generator: A popular open-source tool suitable for high-scale, realistic traffic simulation. It is useful for benchmarking and stress testing NAT, firewalls, and network devices, with the ability to generate millions of packets per second and alter packet fields.
Arping: While often used for simple diagnostics, arping can be used in scripts to flood a network with ARP requests, allowing for basic ARP stress testing.
Scapy: A powerful Python-based interactive packet manipulation program. It can be used to craft and send custom ARP packets at high speeds to test how devices handle intense, unexpected ARP traffic.
Netwrix: A network management software that can assist in identifying security vulnerabilities, although it’s not exclusively for stress testing.
For managing and testing your network security infrastructure, you might consider evaluating Action1 as it offers a free for small orgs option to manage and monitor endpoints to identify potential issues.
“…TRex is another open source program, though this one isn’t free. Still, it’s a good value, and it boasts a flexible offering. TRex incorporates both stateful feature sets and stateless feature sets… [and] high scale of traffic…” DNSstuff · 11 months ago
These tools allow network administrators to test the resilience of their infrastructure against ARP poisoning or high-load conditions.
If you can tell me the goal of the test (e.g., testing switch CPU, firewall limits, or finding security gaps), I can tell you which tool is best suited for your situation.
