Cisco Virtual Wireless Controller Deployment Guide, Release 7.5
Introduction
Introduction
Prior to release 7.3, wireless LAN (WLAN) controller software ran on dedicated hardware you were
expected to purchase. The Virtual Wireless LAN Controller (vWLC) runs on general hardware under an
industry standard virtualization infrastructure. The vWLC is ideal for small and mid-size deployments
with a virtual infrastructure and require an on-premises controller. Distributed branch environments can
also benefit with a centralized virtual controller with fewer branches required (up to 200). This
document is an update for vWLC based on the CUWN 7.5 software release.

vWLCs are not a replacement of shipping hardware controllers. The function and features of the vWLC
offer deployment advantages and benefits of controller services where data centers with virtualization
infrastructure exist or are considered.

Advantages of the vWLC:
•
Flexibility in hardware selection based on your requirements.
•
Reduced cost, space requirements, and other overheads since multiple boxes can be replaced with
single hardware running multiple instances of controllers, Prime Infrastructure (PI) and other
servers (ISE, MSE, VSG / firewall).

servers (ISE, MSE, VSG / firewall).
•
Independent and mutually exclusive instances allow administrators to use multiple virtual
controllers to manage different campuses (or even to manage multiple customer sites) using the
same hardware.
