Inter VLAN routing - best practices/suggestions

L1 Bithead

Hi guys, I've got about 7 or 8 VLANs that segregate my various departments. I want to inspect the traffic that goes from these VLANs to my server VLAN. What's the best way to do that? The only article I could find suggests creating a zone for each department. They are all currently configured as Layer3 subinterfaces on the same VR but this isn't production yet so I can move stuff around if need be.

To add to BPry's recommendation, if you know the servers that will see traffoc (You probably do) you can implement rules for them that allow any application and let it run 30-60 days.  You can then use the migration tool to assign app-ids from he logs (I do not have the instructions handy, but they should be out there) - I've done this a number of times with great sucess


Alternately, I've used Splunk to map the most common applications and endpoints from the logs, to begin building specific rules from that
