The LAN Base image is designed for basic layer 2 switching, suitable for access layers where devices simply need to connect to the network. However, the IP Base image is where the 3750-X shines, offering advanced layer 3 routing capabilities such as OSPF and EIGRP. For network administrators, firmware management begins with selecting the correct feature set. Installing a LAN Base image on a switch intended to perform inter-VLAN routing will result in a non-functional topology, regardless of the hardware’s capabilities. Therefore, firmware management on the 3750-X is inextricably linked to software licensing architecture introduced with this generation.
For new deployments: avoid. For existing networks: run 15.2(4)E8, document your license levels, and prepare for hardware refresh by 2025. cisco 3750x firmware
