Hey, just curious what others show as an average amount of data passed over port 8305 (appliance communications) between their FMC and average FTD in the field in an hour? Is this traffic mostly event logs when no deployments are in progress going from the FTD to the FMC?
We are finding our remote locations roughly have an average of 820 MB of data shown with our SolarWinds netflow data to traverse from a single FTD to our FMC in an hour. To me, that seems high? It's as if we have another staff member their browsing the internet all day long.
If there is a way to reduce that number we would be curious to those suggestions as well. We disabled inline inspection and thought maybe having half the events would reduce the number, but it did not.
Solved! Go to Solution.

The updates can add up. Below is a listing from my lab FTDv showing the files for the various SI feeds. Add up all the sizes for the most recent ones (dated 3 February) and you get 643 MB. By default they update every 2 hours but it can be set lower (like every 20 minutes). That's not including any event logs.

I haven't measured it myself but remember FMC will also be pushing the Security Intelligence feed updates it is receiving from Cisco to the managed devices so that they have a current set of IP addresses and URLs for that feature.

So you're not surprised by the 820MB average traffic in an hour and that's normal for fmc to ftd traffic you think? Between event logs, security intelligence feeds, etc being transferred (not configuration deployments).
