我从2950G-48中运行着Enhanced Image 拷贝到2950启动 show ver 看到还是Running standard Image
是不是普通的2950-24不能运行企业版的IOS吗？
岂不是不能做mac绑定了？

Cisco Catalyst 2950 Series
Software Feature Comparison—Standard Image (SI)
and Enhanced Image (EI) Feature Comparison

The Cisco Catalyst® 2950 Series switches include two software image versions that support different degrees of functionality—the Standard Image (SI) and the Enhanced Image (EI) Software. The version of software depends solely on the model of switch selected, with no upgrade capabilities.

The SI version is embedded in Cisco Catalyst 2950-12, 2950-24, and 2950SX-24 switches, and supports basic Cisco IOS® functionality, Fast Ethernet connectivity, and cluster management.

The EI version supports all that and more. The EI version of software is embedded in Cisco Catalyst 2950T-24, 2950C-24, and 2950G-12, 2950G-24, 2950G-48 switches, and supports advanced intelligent services, gigabit connectivity, and a richer set of features. These include Cisco Spanning-Tree Protocol enhancements for high availability, access control parameters (ACPs) for enhanced security, and Differentiated Services Code Point (DCSP) and rate limiting for advanced quality of service.

The following tables highlight feature comparisons between the fixed-configuration Cisco Catalyst 2950 Series switches with the SI or EI software, and the fixed-configuration Catalyst 2900 Series XL (fixed-configuration Catalyst 2900 XL switches have been discontinued, modular configurations still available).

官方说不可以升级，不知道七哥有没有什么好办法。
