#Default login for cisco virtual wireless lan controller software
In Virtual machine, the vWLC software talks to hypervisor instead of the CPU. Which means on top of this virtual machine, the controller software will be running, in the similar way it does on the physical machine.
Every software container contain its own virtual (i.e., software-based) CPU, RAM hard disk and network NIC.Ī virtual machine is a tightly isolated software container that can run its own operating systems and applications as if it were a physical computer. What virtual machine essentially does is, it creates software container and each software container will represent how we are going to create CPU. Virtual Machines are the fundamental building blocks in a virtualized infrastructure. This is required in case we need to adjust memory or disk size etc. VMware ESX / ESXi hosts can't be managed directly from the console, and all the management of the base platform will be done via vSphere client or vCenter Server in order to access the console. It also allows us to create multiple virtual machines on one machine, but we cannot use hypervisor via console.
The hypervisor is going to control the physical disk access to the CPU which allows us to run virtualization. Hypervisors partition physical servers into multiple virtual machines. Another concept for vCenter is vMotion.ĮSX / ESXi Hypervisor is a software component used in virtualization which allows multiple guest operating systems to run on a host computer all at the same time. vCenter server provides a scalable way for the management of the platform. vCenter Server – The VMware vCenter Server, formerly VMware VirtualCenter, provides a scalable and extensible platform that forms the foundation for virtualization management. This gives us the ability to create and connect to the virtual machine and make changes to the virtual machine.Ģ. vSphere – vSphere is a virtualization infrastructure package from VMware., which includes ESX/ESXi hypervisor, vMotion, DRS, HA, Fault Tolerance and vSphere Distributed Switch. VM components relevant for vWLC - vSphere and vCenter Serverġ. Another advantage is we can run a redundancy between two vWLC on the same box.Įnable features provided by the virtualization software which includes High Availability (HA), ease of migration and fail over protection. This can also save cost in data center.ģ.Independent and mutually exclusive instances allow administrators to use multiple virtual controllers managing different campuses (or even managing multiple customer sites) using the same physical hardware - The users can run multiple instances on a single box. Reduces Cost, Space requirements and other overhead since multiple boxes can be replaced with a single hardware platform running multiple instances of controllers - This will save the clients cost and they can run multiple controllers on this virtual machine. If the virtual controller is installed on a not supported platform, it may not work properly.Ģ. Also make sure that we get the Hardware support checked from VMware site to run the Virtual controller without any issues. We need to use VMware with specific requirements. Flexibility for the customer to select hardware based on their Requirement - So now the end user is not locked into a single piece of hardware. The Virtual Controllers are NOT expected to replace shipping hardware controllers.ġ. Virtual wireless LAN controllers provide flexibility for users to select the hardware based on their requirement i.e. The virtual wireless LAN controller (vWLC) is software that can run on hardware that is compliant with an industry standard virtualization infrastructure. For example we have 5500 Series, 2100 Series, 2000 series, WiSM on CAT6500 etc. Until 7.2 releases, all Wireless LAN controllers (WLC) ran on a dedicated hardware. The vWLC software is available now on Cisco's website.
