ACL TCAM Estimator
Project TCAM consumption for ACL configurations before you deploy them.
Model TCAM utilization for ACL policies on network switches. See projected consumption, headroom, and capacity risk before deploying, and get optimization suggestions to reduce footprint.
What It's Great For
Common scenarios where ACL TCAM Estimator shines
Pre-deployment validation
Check if a new ACL policy will fit on your switch before pushing it to production, avoiding outages.
Capacity forecasting
Project how many months until your current ACLs exhaust TCAM, and plan hardware upgrades.
Policy optimization
Identify wasteful rules and get concrete suggestions to reduce TCAM footprint without changing security posture.
Platform migration planning
Compare TCAM consumption across different switch models to choose the right hardware for your policy.
Compliance auditing
Generate detailed breakdowns of TCAM usage per rule for audit trails and change management.
Quick sanity checks
Use simple mode to quickly estimate if a rule count is feasible on a given platform during design discussions.
Features
What ACL TCAM Estimator can do for you
Multi-vendor ACL parsing
Paste Cisco, Juniper, or Arista configs and auto-detect the vendor for accurate TCAM expansion.
Platform-aware estimation
Choose from 10 switch profiles with real ASIC capacities, entry widths, and double-wide IPv6 support.
Optimization insights
Detect shadowed rules, anti-patterns, and suggest compression or prefix aggregation to reclaim TCAM entries.
Capacity planning
Forecast growth runway, compute rule budgets, and compare platform migrations to stay ahead of capacity.
Simple quick estimates
Get a fast utilization check with just ACE count and mask complexity, no config needed.
Export and share
Export results as JSON, CSV, or CLI commands for documentation and team review.
