Firepower Management still says: Interface 'DataPlaneInterface0' is not receiving any traffic

[roesch4alc]

Hi,

Im still stuck with the message, that you can read in the topic. I think my setup should work, because I created an acl, that redirects traffic to the SFR Modul. But it looks like, that FMC is not receiving andthing. In the moment there is not much data traversing the firewall, but there is traffic.

Im wondering, that "sh service-policy sfr" doesn´t show any hits! Any ideas? What can I do? I already rebootet the sfr modules.

Global policy:+
Service-policy: global_policy
Class-map: sfr
SFR: card status Up, mode fail-open
packet input 0, packet output 0, drop 0, reset-drop 0

Another question: Is it a problem to activate "enable monitor only" mode in a routed firewall mode? I would like to start with this setting, to be sure, that no datastreams will be modified in the first step.

Best regards

Sebastian

Is your class-map sfr set to match all traffic, i.e 'permit ip any any'? Can you get the outputs of the following to confirm:

show run class-map
show run policy-map
show run service-policy

If all of the above look right, one step you can take is to re-apply the service-policy again.

no service-policy global_policy global
service-policy global_policy global

Monitor mode is usually recommended in a non-production environment, but if you are setting it up for the first time, you can start start with that to ensure SFR is receiving the data from the ASA and then move it into fail-open/close.

Also, to note, if you are seeing this on a standby ASA in a failover pair, this is expected as there should ideally be no traffic across that unit.

Any ideas? Should I try to reapply the the service policy?

Yup, the config looks correct. Go ahead and re-apply the service-policy.

Another troubleshooting step you can take before re-applying the policy is to run a packet-tracer to see the packet processing steps that the ASA for traffic traversing through.

The command for that is

packet-tracer input <inside-interface-name> match tcp <internal-ip-address> 12345 4.2.2.2 80 detailed

More on the command is here:

Hope this helps.

Hi,

first I found, that  in my case "same-security-traffic permit inter-interface" was missing. I have several interfaces with the same security level. I added this. So now, the traffic seems to flow as expected.

What do you think? Afterwards I reapplied the service policy ones more. Still no change.

That is really strange. The packet-tracer even shows the packet hitting the SFR module. Did you see any stats change after moving it to monitor-only mode? Also is your SFR policies pushed to the device from the FMC? You could session into the SFR and take a look at if the access policies show up.

BTW what is your ASA and SFR version? Just to make sure everything is compatible.

[Pranay Prasoon]

can you run command "show module sfr detail" and see control plane is up?

[roesch4alc]

Of course.

Please perform a few more test.

a) Generate some traffic and issue command "sh conn | in X" immediately. This will show if traffic is being sent to module.

b) Go to policies->network discovery->Edit the Networks (Make sure both host and application is checked). Save and deploy this.

[roesch4alc]

Hi,

traffic is ongoing, and the acl hitcount grows.

sh conn only shows a summary:

asa# sh conn
21 in use, 27 most used

I tried with sh conn det all, but no connection with X ( X - inspected by service module,) flag is shown.

b)--> was already in place, but i saved it again.

[roesch4alc]

Hi,

today the firewall was placed inline as the gateway for different interfaces. Now the sfr policy redirects traffic to the sfr module and firesight shows up with data...

I think the redirection only works, if connections are going through the asa. Before, there were only broadcasts or multicasts and these won´t be tracked...

So in the moment everything seems to be fine...

Just one more question... In the Summary Dashboard I see "Unique Applications over Time". On the X Axis, there the time is applied. The timezone in user Preferences is set to our local timezone, Berlin. But in the "Unique Applications over Time" Section, the time, is the local time of the SFR Module, that is not correct. See the attachement. Is there a way to correct this?

In contrast to that, the time is correct in Analysis-->Content Explorer--> "Traffic and Intrusion Events over Time".

Thanks to all,

Regards

Sebastian

[Rahul Govindan · Accepted solution]

Glad to hear that it is finally working for you :)

The timezone for "Unique Applications Over Time" can be changed by clicking on the small arrow to the left corner of the Widget and changing the timezone dropdown option.

Picture attached.

[roesch4alc]

Happy new Year!

Thanks a lot, that tip is absolutely correct! In general I would recommend, that the timezone refers to the current users setting... Make more sense than to adjust every gadget for itself....

Hi,

I checked, that polices are applied and up to date, FMC says, that everything is ok, regarding the policies. " Deployment to device successful."

You could session into the SFR and take a look at if the access policies show up.

--> How do I do that? Whats the command/procedure?

ASA Software is 9.6(2) and Firepower is 6.1.0. Everything looks good, but I don´t know whats wrong!

[roesch4alc]

Hi,

I also tried to reapply the policy, in this way, but it doesn´t change anything.

service-policy global_policy global
