Designed for reliable performance in demanding enterprise networks, the Cisco Catalyst WS-C3750X-12S-E Layer 3 Switch combines robust routing, scalable fiber connectivity, and enterprise-grade security in a compact 1U form factor. This switch is engineered to simplify network operations, accelerate application delivery, and improve uptime across branch offices, data centers, and campus deployments. With flexible fiber uplinks, advanced Layer 3 features, and Cisco’s trusted IOS software, it delivers the network intelligence you need to support today’s bandwidth-intensive applications while preparing you for tomorrow’s connectivity needs.

  • High-performance Layer 3 switching with IPv4 and IPv6 support, intelligent routing, and rapid convergence to keep critical applications online. The WS-C3750X-12S-E is built for efficient inter-VLAN routing, dynamic routing protocols, and scalable WAN/LAN integration, ensuring that your network responds quickly to changes in traffic patterns and topology.
  • 12 SFP-based fiber ports offer flexible, high-bandwidth connectivity for access, distribution, and uplink applications. This model is ideal for fiber-rich environments, providing reliable 1000 Mbps uplinks and deep-capacity connectivity to core switches, data center devices, and storage networks while minimizing copper cabling complexity.
  • Stacking and scalability options simplify growth. With Cisco StackWise Plus technology and the potential for stack configurations, administrators can scale capacity and unify management across multiple switches without downtime, enabling seamless expansion as the network footprint expands.
  • Enterprise-grade security and quality of service to protect data and prioritize business-critical traffic. Features such as ACLs, port security, and refined QoS policies help enforce appropriate access control, reduce risk, and guarantee predictable performance for voice, video, and mission-critical applications.
  • Energy-efficient design and Cisco reliability for lower total cost of ownership. The Catalyst 3750X family emphasizes efficient power management and reduced heat output, contributing to lower operating costs and a smaller environmental footprint, while maintaining Cisco’s renowned uptime and serviceability.

how to install Cisco Catalyst WS-C3750X-12S-E Layer 3 Switch

Begin by preparing a clean, well-ventilated 19-inch equipment rack in a secure network closet or data center. Ensure there is adequate airflow around the unit to prevent hot spots. Mount the switch in a 1U slot using the included rack ears, and secure all mounting hardware as per your rack’s guidelines. Once installed, connect the power cable to the appropriate power source and verify that the environmental conditions meet the device’s operating specifications.

Connect your fiber cables to the 12 SFP ports, using the appropriate multimode or single-mode fiber transceivers and patch cables. Label cables clearly to simplify future maintenance and troubleshooting. If you plan to deploy a stack, install the stacking cables between the switches according to Cisco’s stacking guidelines to create a single, resilient management plane with a shared forwarding state.

For initial configuration, connect a management console to the switch via the console port and access the device through the Cisco IOS CLI. Establish a management IP address on a dedicated management VLAN, set up a default gateway, and confirm basic reachability. Create and assign VLANs as needed for your network design, and configure SVI interfaces for inter-VLAN routing if this switch will serve as a layer-3 gateway.

Enable routing features and begin configuring dynamic routing protocols appropriate for your environment, such as OSPF or EIGRP, along with any static routes required for your WAN topology. Implement access control lists and QoS policies to protect critical applications and prioritize traffic like voice and video. Save the running configuration to the startup configuration to ensure changes persist after a reboot.

Test connectivity by pinging gateway devices, verifying route tables with show ip route, and validating the status of each SFP port. If you’re stacking, confirm the stack membership and examine the stackwise status to ensure all units are synchronized. Finally, perform a basic failover test by simulating a link failure or power interruption to verify that redundancy features behave as expected. Schedule routine firmware updates and security patches through Cisco’s recommended maintenance windows to keep the device secure and supported.

For ongoing operations, integrate this switch into your network monitoring and management workflows. Enable SNMP traps for important events, configure Syslog for centralized logging, and synchronize time with an NTP server for accurate event timestamps. Regular backups of the switch configuration, along with periodic health checks and firmware reviews, will help maintain network reliability and reduce troubleshooting time during outages.

Works well!
Size: 8 Fl Oz (Pack of 1)
So far I like this! It is runnier than normal lotion so you don’t need as much. The only thing I don’t like it smells like baby powder to me. But it does work really well with tans!

Love this lotion!!!
Size: 4 Fl Oz (Pack of 1)
The first bottle I received had leaked all over the inside of the package but I sent that back and got a replacement. I love this lotion. I actually first purchased it while I was in Maui 10 years ago. I love the scent of it and it really moisturizes my skin after sunning.

Absolutely the best, no joke
We actually lived on Maui when we discovered Maui Babe, and have been using it ever since. Let me tell you: it is the BEST after sun lotion, bar none. Got a little over-exposed, and are red and hurting? Throw some Maui Babe on, and not only will it relieve the pain (and eventual itching) of sunburn, it'll help prevent peeling later on. It's great as an every day lotion, of course, but it really shines on sunburn. My husband and I laugh about steering many a sunburned tourist to the Maui Babe display in stores all over Hawaii. "Hey, you really need to get some of THIS for that burn." They always seemed grateful to get steered to something that really worked, instead of the usual lotions and potions that didn't. Anyway, I can highly recommend it, been using it for years, and as a blonde who has lived in Hawaii, southwest Florida, and now down in Panama (where the sun is damned close), I can tell you that it really works. And yes...my last order came all the way to Panama because I can't do without it.

Great product!!
Took this with us to Aruba and applied 2x a day. Got a lot of sun, even with sunscreen, but this product kept us from burning. Skin stayed moisturized. Not sticky and smells good too!
