Chapter 3 Installing the Cisco Wide Area Application Engine
Removing or Replacing a Cisco Wide Area Application Engine
The device is in constant communication with the router on your network. When the router notices that the device is no longer responding to it, the router stops sending requests to the device. This is transparent to users. If other devices are attached to the router, the router continues sending requests to the other devices.
When you remove a device, the pages that were cached on that device are no longer available to the router or other devices, and you might see an increase in outgoing web traffic that might have otherwise been fulfilled by the device that you are removing. However, after a time, the router and other devices redistribute the load of web traffic.
If you remove the last device from your network, you can also disable device support on the router. However, this is not necessary; having device support enabled when there are no devices attached has no effect on the router’s performance.
To replace a device, remove it from the network, and then install a new device. Configure it using the same configuration parameters (IP address, and so forth) that you used for the removed device.
