How to Migrate from Cisco 2960X to 9200L Switches

The Cisco Catalyst 2960X series has long been a reliable workhorse for enterprise access layers. However, with the platform reaching its End-of-Life (EOL) milestones, IT teams face pressure to migrate to modern, supported solutions. The recommended migration path leads to Cisco Catalyst 9200 Series Switches, particularly the C9200L models, which provide improved performance, enhanced security, and the flexibility of modern Cisco IOS XE software. This guide offers a comprehensive approach for network engineers and IT procurement teams to handle this transition efficiently.

Part 1: Understanding the 2960X EOL Risk

Cisco officially announced the End-of-Life and End-of-Sale dates for the Catalyst 2960X family in 2020. Continuing to operate these switches past the deadlines carries several risks:

• Software Risk: Final software maintenance or bug fixes ended on October 31, 2023.
• Security & Support Risk: The last date of support is October 31, 2027. Beyond this, TAC support is unavailable, leaving potential vulnerabilities unaddressed.

Understanding this timeline is critical for planning a smooth migration to ensure business continuity and network security.

Part 2: Technical Comparison – 2960X vs. 9200L

Migrating from 2960X to 9200L involves software, hardware, and architectural differences that require careful planning.

Software and Management

PoE and Stacking

• PoE: Both platforms support PoE+. 9200L “P” models (e.g., C9200L-48P-4G) support PoE+, while higher power requirements may need C9300 series.
• Stacking: 2960X FlexStack modules are replaced by C9200L-STACK-KIT on the new platform.

Product Mapping (2960X → C9200L)

Direct replacement options for common EOL models:

Part 3: Step-by-Step Migration Guide

Since Cisco does not offer an automatic migration tool, the process relies on careful configuration review and manual verification.

Step 1: Backup and Cleanup

1. Backup Existing Config: Save running-config from the 2960X.
2. Filter Incompatible Commands: Remove legacy QoS and stacking commands; most VLAN, trunk, and SNMP settings are transferable.

Step 2: QoS Migration

Old 2960X commands like mls qos and srr-queue must be replaced. Use auto qos on 9200L:

Example CLI configuration to implement modular QoS:

interface GigabitEthernet1/0/1
 description Phone and Computer
 switchport mode access
 switchport access vlan 21
 switchport voice vlan 80
 spanning-tree portfast
 auto qos voip cisco-phone
!

Step 3: Stacking Configuration

Use C9200L-STACK-KIT for stacking. 9200L commands differ, but stack architecture ensures resilience.

Step 4: PoE Optimization

1. Enable LLDP globally:

   (config)# lldp run

2. Verify LLDP/CDP on interface:

   (config-if)# lldp transmit
   (config-if)# lldp receive

3. Static Power Allocation (if needed):

   (config-if)# power inline static max 

Part 4: Risk Management and Hybrid Strategies

• Phased Migration: Run 9200L and 2960X concurrently to maintain VLAN/trunk compatibility.
• Alternative Options: Catalyst 1000 series retains classic IOS CLI if immediate IOS XE adoption is not feasible.
• Pilot Testing: Always test a single switch or lab stack before full deployment.

Part 5: Procurement and Supply Chain Considerations

Migrating hardware can be delayed by supply chain and budget constraints.

Router-switch Advantages:

• In-Stock Inventory: Popular 9200L models ready for global dispatch.
• Fast Delivery: 24–48 hour shipping to meet tight project deadlines.
• Technical Guidance: Assistance with model mapping, PoE planning, and configuration strategy.
• Flexible Payment: Support for different procurement budgets.

FAQ

Can I mix 2960X and 9200L in the same stack?

No. Stacking hardware is incompatible; keep them in separate stacks.

What about Smart Licensing on 9200L?

Unlike 2960X RTU/PAK files, 9200L uses Smart Licensing. Register the switch with a Cisco Smart Account, or use SLR in isolated networks.

How do I handle non-Cisco PoE devices?

Enable LLDP globally and verify negotiation per interface. If devices fail, consider static power allocation.

How long can 2960X coexist with 9200L?

For phased migration, you can run both platforms concurrently until all ports and VLANs are migrated. Avoid stacking together.

Are refurbished 9200L units safe to use?

Certified refurbished devices maintain warranty and reliability, useful for cost-sensitive migrations, especially if sourced from trusted vendors like Router-switch.

Conclusion: Migrating from Cisco 2960X to 9200L switches is essential for security, support, and performance. By carefully reviewing configuration differences, adopting modular QoS policies, planning stacking and PoE, and sourcing hardware from reliable suppliers, IT teams can ensure a smooth transition. Leveraging vendors with verified stock, fast global delivery, and technical guidance—such as Router-switch—helps reduce deployment risk while maintaining enterprise network stability.
