Usage Guidelines
This command is not normally needed for typical operations because the router's onboard hardware
accelerator for IPSec encryption is enabled by default. The hardware accelerator should not be disabled
except on instruction from Cisco TAC personnel.
Examples
The following example shows how to enable the router's onboard hardware accelerator for IPSec
encryption. This operation is normally needed only after the accelerator has been disabled for testing or
debugging purposes.
Router(config)# no crypto engine accel
