Test-NetStack: A network integration testing tool

Synopsis

Test-NetStack is a PowerShell-based testing tool that performs ICMP, TCP, and RDMA traffic testing of networks. Test-NetStack can help identify potential network (fabric and host) misconfiguration or operational instability.

Test-NetStack can validate the various network data paths on Windows, testing native, synthetic, and hardware offloaded (RDMA) data paths for issues with:

• Connectivity
• Packet fragmention
• Low throughput
• Congestion

Test Details

Test-NetStack first performs connectivity mapping across a cluster, specific nodes, or IP targets then tests:

- Stage1: ICMP Connectivity, Reliability, and PMTUD
- Stage2: TCP Stress 1:1
- Stage3: RDMA Connectivity
- Stage4: RDMA Stress 1:1
- Stage5: RDMA Stress N:1
- Stage6: RDMA Stress N:N

For more information, run:

help Test-NetStack

Install the Tool

Install-Module Test-NetStack

Run the Tool

$NetStackResults = Test-NetStack

$NetStackResults = Test-Netstack -Nodes 'Node1', 'Node2', 'NodeN'

$NetStackResults = Test-Netstack -IPTarget '192.168.1.1', '192.168.1.2', '192.168.1.3', '192.168.1.4'

Testable vs Disqualified Networks

Test-NetStack will identify networks that can and cannot be tested. To review the Test-NetStack networks that will be tested, use:

$NetStack.TestableNetworks

To review the Test-NetStack networks that cannot be tested.

$NetStack.DisqualifiedNetworks
