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:

	Command	Purpose
Step 1	no crypto engine [slot accelerator]	Disables the C7200 VSA.
	0
Step 2	crypto engine [slot accelerator] 0	Enables the C7200 VSA after it has been
		disabled.
		Note See Table 1-5for more details.
