hese sections provide a greater insight into the architecture of the Cisco 2500 Series Wireless Controller.
The Cisco 2500 Series Wireless Controller physically has the same form factor as the Cisco 2106 controller. The CPU on a Cisco 2500 Series Wireless Controller is a multi-core CPU and can handle both data plane and wireless data traffic. The CPU can handle control plane application, which handles all the management traffic needed to "control" a wireless network.
The Cisco 2500 Series Wireless Controller has 1 GB system memory. Two types of memory devices are supported in order to store software images. The boot flash contains the boot code, and the compact flash contains the application code that can store multiple images. The front panel houses four Gigabit Ethernet ports. Two of the ports are 802.3af capable. All ports will transfer the traffic to/from the wireless network.
The Power over Ethernet (PoE) ports on the Cisco 2500 Series Wireless Controller will not support directly attached APs although those APs might power up and join, it is not a supported scenario.
再说 一下WLC 2500 上的端口问题, Ethernet ports on the Cisco 2500 Series Wireless Controllers do not work as Switch ports (
that is, two machines directly connected to these ports cannot communicate with each other
