Configuring Automatic Upgrades

•For the output of the show statistics host command, see Displaying Statistics, page 17-28.

•For the IDM procedure for automatically upgrading the sensor, refer to Configuring Automatic Update. For the IME procedure, refer to Configuring Automatic Update.

•For more information about copying, displaying, and erasing upgrade files, see Working With Upgrade Files, page 21-6.

Applying an Immediate Update

Caution While executing the autoupdatenow command, you cannot use the CLI, or start any new sessions until the upgrade is complete. Do not execute any commands while automatic update is in progress. Wait at least five minutes before checking results and executing other commands.

Use the autoupdatenow command to perform an immediate update on the sensor. You receive a warning that this command performs an update on the sensor immediately. After executing this command, disable the user-server/cisco-serveroptions in the auto-upgrade settings in the service host submode, if you do not want scheduled automatic updates.

Note You must have either a DNS or HTTP proxy server configured to download automatic updates from cisco.com.

Note You must have automatic update configured and a valid license to apply updates.

To perform an immediate update on the sensor, follow these steps:

Step 1 Log in to the sensor using an account with administrator privileges.

Step 2 Start immediate automatic update.

sensor# autoupdatenow

Warning: Executing this command will perform an auto-upgrade on the sensor immediately. Before executing this command, you must have a valid license to apply the Signature AutoUpdates and auto-upgrade settings configured.After executing this command please disable user-server/cisco-server inside 'auto-upgrade' settings, if you don't want scheduled auto-updates

Continue? []:

Step 3 Enter yes to continue. The update is applied.

Step 4 Check to see if the update was applied.
