If you sourcetype your events the way that the Cisco apps expect it, then the field extractions should work. The sourcetypes are like cisco:ios, etc. If you show a valid raw event, I will give you the RegEx you need, but really, it should already be there for you.

hi jthomp7626,
There are Add-on built for most (if not all) Cisco products with all extractions pre configured.
check splunkbase and search for cisco, pick the right add on and Splunk your data
