We are trying to setup a 2811 router to run IOS based IPS. We followed all the procedures but we can't seem to get the system to send any alerts via syslog. We have tried various port scanners with no luck. Are we missing something?
Your configuration seems ok. Can you please provide the following output:
1. show ip ips signature (as attachment)
2. What port scanning tool you used and how you used it.
Your configuration has syslog/sdee enabled.If you have configured syslog server properly, the ips alerts will be sent to syslog server. So the question is whether IPS actually working and will be able to trigger events as expected.
If you know how to use metasploit, you can try use that to test it. "3Com 3CDaemon FTP Server Overflow" should trigger signature 3166/3173. (Use 'show ip ips signautre | in 3166' to check, it should show something like "3166:0 Y Y A HIGH 0 1 0 0 0 FA N 100 S190")
