PBR/ACL Configuration Validator for L3 Switches
TL;DR
Pre-deployment validation tool for network engineers and IT admins at SMBs/MSPs managing L3 switches that simulates traffic flow to detect PBR/ACL conflicts, loops, or blackholing and provides step-by-step fixes so they can eliminate outages and save 5+ hours/week in troubleshooting.
Target Audience
Network engineers and IT admins at small to mid-sized businesses, as well as managed service providers (MSPs) managing enterprise networks with L3 switches.
The Problem
Problem Context
Network engineers and IT admins set up VLANs and PBR (Policy-Based Routing) rules to control traffic between VLANs. They need traffic crossing VLANs to pass through a firewall for security rules. Misconfigurations in PBR/ACL rules often cause network outages, breaking access to critical systems.
Pain Points
Users manually create ACLs and PBR rules, but enabling them often breaks network access. They lack a way to test configurations before applying them to live networks. Current workarounds (trial-and-error, hiring consultants) waste time and risk downtime.
Impact
Network outages cost businesses thousands per hour in lost productivity. Engineers waste 5+ hours per week troubleshooting misconfigurations. Security policies fail to enforce, exposing the network to risks.
Urgency
Network issues cannot wait—every minute of downtime impacts revenue and operations. Engineers need a way to validate rules before deployment to avoid costly mistakes. Without a solution, they risk repeated outages and security gaps.
Target Audience
Network engineers, IT admins, and managed service providers (MSPs) managing enterprise networks with L3 switches (Dell, Cisco, HP). Small to mid-sized businesses with complex VLAN setups also face this problem.
Proposed AI Solution
Solution Approach
A web-based tool that validates PBR and ACL configurations before deployment. Users input their rules, and the tool simulates traffic flow to detect conflicts, loops, or misconfigurations. It provides clear error messages and suggests fixes, ensuring rules work as intended before applying them to live networks.
Key Features
- Conflict Detection: Identifies overlapping or conflicting rules that could break network access.
- Firewall Integration Check: Validates that traffic correctly routes to the firewall for security policies.
- Step-by-Step Fixes: Provides actionable feedback to resolve issues without deep expertise.
User Experience
Users copy their PBR/ACL rules into the tool’s interface. The system analyzes them in seconds, highlighting errors and suggesting fixes. They apply only the validated rules to their switches, avoiding outages. Engineers save hours per week by catching mistakes early.
Differentiation
No existing tool specifically validates PBR/ACL configurations for L3 switches. Unlike generic network monitors, this tool proactively prevents misconfigurations before they cause downtime. It’s designed for non-experts, reducing the need for costly consultants.
Scalability
Starts with support for Dell N2224X-ON and expands to other L3 switch models (Cisco, HP). Adds firewall integration checks and automation for MSPs. Tiered pricing scales with network complexity and team size.
Expected Impact
Eliminates network outages caused by PBR/ACL misconfigurations. Saves engineers 5+ hours per week in troubleshooting. Ensures security policies enforce correctly, reducing risks. Lowers costs by replacing manual trial-and-error with automated validation.
