Hi, i would like to know how often does Cisco release updates for the Signature engine for the IPS appliances? I was not sure to make the auto update from Cisco.com to be every-day, every-hour or once a week?
Also can you advise me of the recommended setting for Bypass feature for the interfaces?
Since the auto-update checks go out the management interface it maybe better to have it set for every hour. That way you wont have delays in the critical updates. Assuming you are in inline traffic mode, setting the bypass to "auto" is the recommended setting for interfaces. That is also the default.
