Enable Syslog Notification

Check to enable the router to send alarm, event, and error messages to a syslog
server. A syslog server must be identified in System Properties for this
notification method to work.

Enable SDEE Notification

Check to enable the router to record SDEE notification events.
Maximum number of SDEE events to store
Specify the maximum number of SDEE events that you want the router to store.
The more events that you allow the router to store, the more memory is used.
Number of concurrent SDEE subscriptions (1-3)
An SDEE subscription is a live feed of SDEE events. Enter the number of SDEE
subscriptions that you want the router to use, to a maximum of 3.

Enable Engine Fail Closed

By default, while IOS compiles a new signature for a particular engine, it allows
packets to pass through without scanning for the corresponding engine. Enable
this option to make IOS drop packets during the compilation process.

Use Built-in Signatures (as backup)

If IPS does not find or fails to load signatures from the specified location(s), it can
use the IOS built-in signatures to enable IPS. This option is enabled by default.
