This example shows the basic configuration necessary to load the 128MB.sdf file onto a router running Cisco IOS IPS. Note that the configuration is almost the same as when you load the default signatures onto a router, except for the ip ips sdf location command, which specifies the 128MB.sdf file. Cisco IOS IPS starts loading signatures when the very first IPS rule is enabled on an interface.
