Critical VLAN support for voice devices allows a fallback mechanism when the authentication server is unreachable, for example, when the WAN link is down.

In the new GNS3 1.4, there is a way to run a second category of switches and routers. The IOS of the actual device is necessary to emulate the Cisco router with GNS3.This section explains how to download the IOS image file for an actual. For older images, we use and maintain Dynamips an emulator dedicated to emulate some Cisco hardware. If the authentication server becomes unreachable, IP phones cannot authenticate and therefore do not have connectivity. GNS3 offers multiple ways to emulate IOS.
Critical VLAN support for voice devices: Under normal circumstances, when an IP phone successfully authenticates on a port, the authentication server puts the phone into the voice domain. ASP can now leverage Device Classifier (DC) for device classification and execute the configuration macro associated with it for these new device types.
AutoSmartPorts (ASP) automates the process of interface configuration by applying pre-defined configuration on an interface when a device is connected to the interface, and removing the configuration when the device is disconnected. The enhanced Device Classifier provides increased device visibility for the following new devices: Apple devices, 3 rd party phones and APs, 3 rd party printers, Cisco phones and conference systems, Cisco wireless LAN controllers, Cisco IP cameras, Cisco APs, Cisco digital media players, gaming consoles, smart phones among others.
