Upgrading the Sensor

Note The CLI output is an example of what your configuration may look like. It will not match exactly due to

the optional setup choices, sensor model, and IPS 7.1 version you have installed.

To upgrade the sensor, follow these steps:

Step 1 Download the appropriate file to an FTP, SCP, HTTP, or HTTPS server that is accessible from your

sensor.

Step 2 Log in to the CLI using an account with administrator privileges.

Step 3 Enter configuration mode.

sensor# configure terminal

Step 4 Upgrade the sensor.

sensor(config)# upgrade url/IPS-SSP_10-K9-7.1-3-E4.pkg

The URL points to where the update file is located, for example, to retrieve the update using FTP, enter

the following:

sensor(config)# upgrade ftp://username@ip_address//directory/IPS-SSP_10-K9-7.1-3-E4.pkg

Step 5 Enter the password when prompted.

Enter password: ********

Step 6 Enter yes to complete the upgrade.

Note Major updates, minor updates, and service packs may force a restart of the IPS processes or even

force a reboot of the sensor to complete installation.

Note The operating system is reimaged and all files that have been placed on the sensor through the

service account are removed.

Step 7 Verify your new sensor version.
