To clear the packet capture buffer, perform the following task:
Command

Using the Configuration Checkpoint and Rollback Service

This section describes how to make a checkpoint (or snapshot) of a running configuration on your ACE
and how to use the rollback service to revert to the last known stable configuration.
At some point, you may want to modify your running configuration. If you run into a problem with the
modified configuration, you may need to reboot your ACE. To prevent having to reboot your ACE after
unsuccessfully modifying a running configuration, you can create a checkpoint (a snapshot in time) of a
known stable running configuration before you begin to modify it. If you encounter a problem with the
modifications to the running configuration, you can roll back the configuration to the previous stable
configuration checkpoint.
The ACE allows you to make a checkpoint configuration at the context level. The ACE stores the
checkpoint for each context in a hidden directory in Flash memory. If after you enter additional
commands to modify the current running configuration, you enter the rollback command option, the
ACE causes the running configuration to revert to the checkpointed configuration.
