You have 2 options.

Option 1 - use a Splunk 5.x Heavy Forwarder to connect to your IPS and forward the logs to your Splunk 6 instance.

Option 2 - there is a potential workaround to get IPS working on Splunk 6 here -> http://answers.splunk.com/answers/105193/cisco-ips-error-errno-8?page=1&focusedAnswerId=135759#13575...

The problem lies in how Cisco IPS units establish SSL connections. Basically they do so incorrectly. Older versions of OpenSSL were able to cope with this, however newer versions don't. As Splunk 6.x uses newer OpenSSL versions the effect is that the Cisco IPS app doesn't work in 6.x but works in 5.x (which uses an older OpenSSL version).

I haven't heard of any other viable workarounds than to simply run the app on a 5.x instance.
