Usage Guidelines After you use the clear cache dre command, the first 1 MB of data is not optimized. The Cisco WAAS

software does not optimize the first 1 MB of data after a restart of the tcpproxy service. The data that is

transmitted after the first 1 MB of data will be optimized according to the configured policy.

The clear cache dre command may cause the system to reboot, but you are asked to confirm before the

command continues and you are given a chance to save any configuration changes that have been made

to the running configuration.

Examples The following example shows how to clear the CIFS cached objects on the WAAS device:
