Tip: If you are not sure whether the IDP appliance requires a reboot, log in to ACM. The ACM home page indicates whether the IDP appliance is in a state that requires or does not require a reboot.

Note: The reboot command is different from idp.sh restart, which restarts the IDP processes.

You shut down the IDP appliance under the following circumstances:

• Before replacing cold-swappable components, such as I/O modules on high-end models and power supplies on low-end models.

Note: If you have enabled internal bypass, traffic passes through the IDP device uninspected when IDP is shut down.
