Cisco Catalyst 3750-X series, as stackable switches, are enterprise-grade products. These switches provide continuous connectivity, scalability, security, energy efficiency and ease of operation through innovative features such as Cisco StackPower, IEEE 802.3at Enhanced Power over Ethernet (PoE+) configuration, optional network modules, redundant power supplies, and Media Access Control Security(MACsec), etc.

Stackwise Technology, an innovative stacking architecture, is used on Cisco 3750 Series switches to provide 32Gbps stacking interconnect. It can connect up to 9 switches and turn them into a unified, logical and convergence-optimized device so that users can deploy voice, video and data application comfortably. Cisco 3750 series switches adopt the way of backplane bandwidth stack, and the models themselves have stacking ports and can reach 32G backplane bandwidth by using specific stacking lines

As an innovative product, the Cisco 3750 switch plays an important role in many places. It is positioned at the enterprise switch and has excellent performance in terms of performance parameters and function settings. We may encounter some problems during the actual use. The following is about how to troubleshoot the Cisco 3750 series switches.
