Upgrading the Sensor

Upgrade Notes and Caveats

For a list of the upgrade notes and caveats for each IPS version, refer to the Release Notes for your IPS

version found at this URL:

http://www.cisco.com/en/US/products/hw/vpndevc/ps4077/prod_release_notes_list.html

Manually Upgrading the Sensor

Note During a signature upgrade all signature configurations are retained, both the signature tunings as well

as the custom signatures. During a signature downgrade the current signature configuration is replaced

with the old signature configuration. So if the last signature set had custom signatures and/or signature

tunings, these are restored during the downgrade.

Caution You must log in to Cisco.com using an account with cryptographic privileges to download software. The

first time you download software on Cisco.com, you receive instructions for setting up an account with

cryptographic privileges.

Note Do not change the filename. You must preserve the original filename for the sensor to accept the update.

Use the upgrade source-url command to apply service pack, signature update, engine update, minor

version, major version, or recovery partition file upgrades. The following options apply:

• source-url—Specifies the location of the source file to be copied:

–

ftp:—Source URL for an FTP network server. The syntax for this prefix is:

ftp://[[username@]location][/relativeDirectory]/filename

ftp://[[username@]location][//absoluteDirectory]/filename

Note You are prompted for a password.

–

scp:—Source URL for the SCP network server. The syntax for this prefix is:

scp://[[username@]location][/relativeDirectory]/filename

scp://[[username@]location][//absoluteDirectory]/filename

Note You are prompted for a password. You must add the remote host to the SSH known hosts

list.

–

http:—Source URL for the web server. The syntax for this prefix is:

http://[[username@]location][/directory]/filename

Note The directory specification should be an absolute path to the desired file.
