What You Can Achieve
Representative results from NetGUI deployments across different industries and use cases
The examples below are representative deployment scenarios based on common customer environments and outcomes
Representative University Campus Upgrade
Typical Scenario - 300+ Switch Infrastructure
Challenge
A major university needed to upgrade 327 Catalyst switches across a 200-acre campus to address critical security vulnerabilities (CVE-2023-20198). The network team of 5 engineers faced a daunting task: manually upgrading each switch would take approximately 3 weeks of round-the-clock work during summer break, with high risk of configuration errors and extended downtime.
Additional Constraints
- Limited maintenance window (3-night weekend period)
- Strict uptime requirements for research networks
- Multiple switch models (C9300, C9400, C3850)
- Stacked configurations (2-4 switches per stack)
- Compliance documentation required for auditing
Solution Approach
Phase 1: Pre-Flight (Week 1)
- Imported all 327 switches into NetGUI
- Configured model-to-image mappings for all switch types
- Ran flash capacity checks across entire fleet
- Cleaned up unused images (freed 85GB total)
- Captured pre-upgrade baselines
Phase 2: Execution (Weekend)
- Night 1: Uploaded IOS images to all switches (automated)
- Night 2: Set boot variables and scheduled reboots by building
- Night 3: Post-upgrade verification and comparison
Phase 3: Validation
- Automated pre/post configuration comparison
- Verified all CDP/LLDP neighbors matched
- Confirmed all interfaces operational
- Generated compliance report for IT security
Results
Key Benefits Realized
- Completed in 15% of estimated manual time
- Zero configuration errors or lost settings
- Complete audit trail for security compliance
- Repeatable process for future upgrades
Why This Works
Automated verification ensures nothing is missed. Pre/post configuration comparison catches issues before they become problems. The repeatable process means future upgrades are even faster.
Representative Multi-Site WLAN Refresh
Typical Scenario - 75 Locations, 450 Access Points
Challenge
A national retail chain needed to replace 450 aging access points across 75 store locations within a 60-day window. Each store had 6-8 APs serving customer WiFi, POS systems, and inventory scanners. The existing process of manually configuring each AP was taking 30-45 minutes per device, requiring expensive on-site visits or remote hands coordination.
Operational Requirements
- Minimize customer-facing WiFi downtime
- Maintain consistent configurations across locations
- Work with remote hands technicians (non-network staff)
- Document all changes for PCI compliance
- Verify client connectivity post-replacement
Solution Implementation
Standardization Phase
- Created configuration templates for store types (small/medium/large)
- Documented all existing AP settings in NetGUI
- Prepared site-specific parameter files
Execution Rollout
- Piloted at 5 stores to refine process
- Trained remote hands on QR code scanning
- Used AP Replacement Wizard for guided workflow
- Replaced 8-10 stores per day (60 APs)
- Network team monitored remotely via dashboard
Validation & Documentation
- Automated RF environment verification
- Client connectivity testing per SSID
- Auto-generated replacement reports
- Consolidated documentation for all 75 sites
Outcomes
Business Impact
- Estimated $150K–200K saved in labor and site visit fees
- Minimal downtime averaging 6 minutes per location
- PCI compliance maintained with complete documentation
- Enabled remote hands non-network staff successfully completed replacements
Why This Works
The guided AP Replacement Wizard enables non-network staff to complete replacements. Configuration templates ensure consistency across all locations. Automated documentation satisfies compliance requirements.
