Ensure that the Cavium Driver is up to Date

(Bivio 7000 appliances only)

If you want to use the SSL decoding functionality, you must ensure that your Network Appliance is using the latest Cavium driver. This is because the NBA offloads the computationally expensive cryptographic operations to Cavium CN1615 Security Processor cards, freeing the Bivio CPUs from this task and thereby maintaining high performance.

To update the Cavium driver

Note: In steps 2 and 3, the version numbers are examples. Replace the examples with the appropriate version numbers.

1. Check which version of the Cavium driver is currently installed. To do this, execute the following command from an NBA CPU-X login:

   rpm -qa | grep cavium
   

   This shows the version of the Cavium rpm that is currently installed (for example, cavium-1.00-3).

2. If the installed version is older than the version on CA Support Online in patch RO26711, CA DLP Network Support for SSL Decoding, delete the existing version.

   To delete the existing version, execute the following command:

   rpm -e cavium-1.00-3
   

   The version number shown here is an example. Replace this example with the appropriate version number.

3. Install the new version of the Cavium rpm. To do this, execute the following command in the directory where the .rpm is present:

   rpm -ivh cavium-1.00-7a.ppc.rpm 
   

   The version number shown here is an example. Replace this example with the appropriate version number.

4. Reboot the CA DLP Network appliance. To do this, execute the following command:

   nrsp reboot system
