The Console Port and Distribution System Ports are found on all WLCs.įigure 1. Depending on the WLC model, some ports might or might not be present. We will now take a look at the different ports that can be found on WLCs and explain their purpose. This will help maximize the stability and scalability of any WLC deployment by correctly configuring all necessary interfaces and attached devices. It is important that engineers working with WLCs, understand the purpose of each interface and how it should be used. WLC Interface Concepts – Understanding Ports and Logical InterfacesĮvery WLC is fitted with a number of ports ( physical interfaces) and logical interfaces, all critical for the device’s proper operation and integration with the network infrastructure.
Users can freely download Cisco's WLC product portfolio in our Cisco's Wireless Controller Datasheets download section. The datasheets contain all currently available WLC models, brief specification overview/comparison and much more. This article continues by explaining the purpose and functionality of each WLC interface ( Management interface, Virtual interface, AP-Manager interface, Dynamic interfaces etc), WLC Port ( Service port, Redundant port, Distribution ports etc), how WLCs connect to the network infrastructure, VLAN requirements and mapping to SSIDs. Our previous article introduced Cisco’s popular Wireless Controller ( WLC) devices and examined their benefits to enterprise networks, different models offered and finally took a look at their friendly GUI interfaces.
