I have completed a comprehensive analysis of the Cisco 4000 Series Router market and product trends for 2025-2026. The series reached its end-of-sale in late 2023, and the market is now rapidly shifting toward the Catalyst 8000 Edge Platforms to support AI-driven network demands.

Key findings included in the report:

  • Critical Deadlines: Software maintenance ends in August 2025, with final security support expiring in November 2028.
  • AI Momentum: Enterprise demand for "AI-ready" networks is driving a massive refresh cycle, with Cisco reporting billions in AI-related infrastructure orders.
  • Supply & Pricing: Expect tighter supply and higher costs for new hardware components (memory, optics) through late 2026.
  • Migration Strategy: Direct replacement paths are established (e.g., ISR 4331 to Catalyst 8200), though a secondary market for legacy units remains active for non-critical budget-conscious projects.

For a detailed breakdown of EOL milestones, replacement models, and real-time market pricing, please refer to the report below.

The Cisco 4000 series is nearing its end-of-life. You can explore your next steps here:
