Chapter 1 Overview
Enabling/Disabling the VSA
Enabling/Disabling the VSA
This section includes the following topics:
• Disabling the VSA during Operation, page 1-6
• Enabling/Disabling Scheme, page 1-6
The VSA crypto card does not support OIR. The VSA boots up only during system initialization. The
VSA will not work if it is inserted after the system is up and running. The VSA can be shut down by a
disabling CLI command. The VSA is ready for removal after the disabling CLI command is executed.
Disabling the VSA during Operation
Before removing the VSA, we recommend that you shut down the interface so that there is no traffic
running through the VSA when it is removed. Removing an VSA while traffic is flowing through the
ports can cause system disruption.
Caution You could damage the VSA, if you remove the VSA without entering the CLI command.
To disable the C7200 VSA, use the following commands, starting in global configuration mode:
