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.
