Vol 2-2 Flashcards
autonomous AP
autonomous AP
A wireless AP operating in a standalone mode, such that it can provide a fully functional BSS and connect to the DS.
CAPWAP
A standards-based tunneling protocol that defines communication between a lightweight AP and a wireless LAN controller.
centralized WLC deployment
A wireless network design that places a WLC centrally within a network topology.
cloud-based AP
A wireless AP operating much like an autonomous AP, but having management and control functions present in the Internet cloud.
cloud-based WLC deployment
A wireless network design that places a WLC centrally within a network topology, as a virtual machine in the private cloud portion of a data center.
connected mode
The operational mode used by a FlexConnect AP when the path back to its controller is up and working. In this mode, all wireless traffic flows over the CAPWAP tunnel to and from the controller.
controller-less wireless deployment
A wireless design based on an embedded wireless controller (EWC), where the WLC function is co-located with an AP, rather than a discrete physical controller.
distributed WLC deployment
A wireless design based on distributing multiple controllers within the network. Each of the controllers commonly supports a relatively small number of users.
embedded wireless controller (EWC)
A WLC function that is co-located within an AP.
embedded wireless controller (EWC) deployment
A wireless network design that places a WLC in the access layer, co-located with a LAN switch stack, near the APs it controls.
FlexConnect mode
An AP mode tailored for remote sites. Wireless traffic flows to and from a controller if the AP’s CAPWAP tunnel is up, or is locally switched if the tunnel is down.
Media Access Control (MAC) layer
The lower of the two sublayers of the data-link layer defined by the IEEE. Synonymous with IEEE 802.3 for Ethernet LANs.
split-MAC architecture
A wireless AP strategy based around the idea that normal AP functions are split or divided between a wireless LAN controller and lightweight APs.
standalone mode
The operational mode used by a FlexConnect AP when the path back to its controller is down and not working. In this mode, all wireless traffic is switched locally, preserving local connectivity while the AP is isolated from its controller.
wireless LAN controller (WLC)
A device that cooperates with wireless lightweight access points (LWAP) to create a wireless LAN by performing some control functions for each LWAP and forwarding data between each LWAP and the wired LAN.
