Context
Large Cisco ACI fabrics where configuration and operational state are extensive, deeply nested and difficult to review by hand.
01
The challenge
- Design validation and troubleshooting depended on manually reading thousands of lines of fabric output.
- Inconsistencies between intended design and deployed policy were hard to spot.
- Assessment work was slow and not repeatable across fabrics.
02
Our approach
- Parsers that convert ACI configuration and operational data into a structured, queryable model.
- Rule sets that check the model against design standards and known anti-patterns.
- Reports that surface the specific tenants, policies or paths needing attention.
03
The outcome
- Repeatable fabric assessments with consistent, evidence-backed findings.
- Faster troubleshooting by isolating the relevant objects instead of reading everything.
- Design deviations identified before change windows.
