Chapter 3 Installing the Wide Area Virtualization Engine

Removing or Replacing a WAVE Appliance

When you remove a WAVE appliance, the pages that were cached on that device are no longer available to the router or other WAVE appliances. You might see an increase in outgoing web traffic that might have otherwise been fulfilled by the WAVE appliance that you are removing. However, after a time, the router and other WAVE appliances redistribute the load of web traffic.

If you remove the last WAVE appliance from your network, you can also disable WAVE appliance support on the router. However, this action is not necessary because leaving WAVE appliance support enabled when there are no WAVE appliances attached has no effect on the router’s performance.

To replace a WAVE appliance, remove it from the network, and then install a new WAVE appliance and configure it using the same configuration parameters (IP address and so forth) that you used for the removed WAVE appliance.
