Why Cisco GLC-TE Is a Future-Proof Investment

1. Compatibility Across Generations of Hardware

Unlike proprietary or limited-use modules, GLC-TE is broadly compatible with Cisco’s extensive lineup of:

• Catalyst switches (2960, 3650, 9300)
  
  

• Nexus data center switches
  
  

• Integrated Service Routers (ISR)
  
  

• MSA-compliant third-party devices
  
  

This means your GLC-TE investment will work now and in the future, even as you upgrade your core infrastructure.

2. Gigabit-Ready Performance with Existing Cabling

By supporting 1 Gbps Ethernet over copper, the GLC-TE allows you to maximize performance using your existing cabling infrastructure:

• No need for fiber runs
  
  

• No rewiring costs
  
  

• Upgrade-ready across office floors or campuses
  
  

Security Benefits of GLC-TE

Security doesn’t begin at the firewall—it starts at the port. Here’s how GLC-TE helps secure your physical and logical layers:

The ability to integrate with Cisco’s security policies ensures you’re not just speeding up traffic, but also controlling it.

Long-Term Cost Savings and ROI

GLC-TE pays for itself by reducing future upgrade and maintenance costs—making it a smart asset in any long-term IT strategy.
