user-identification for VLAN Traffic

L4 Transporter

Hi Guys,

I am just wondering if any one could help me out on this as I am slightly lost creating and troubleshooting for the following issue:

It has been noticed that not all traffic had a user-id and it seems that any traffic originating from a VLAN goes down as “unknown” user. 

So my question is, how can we make the PAN aware of the VLANS so that we can see if the change makes the users visible rather than remaining as unknown.

Hope this information helps.  Looking forward to hear from you guys.

Many Thanks...

To add to this, traffic originating from network on a vlan has no access to the internet as well.  Looking at the traffic logs, it shows application as "incomplete".  As far as I understand, incomplete traffic is when the 3-way handshake is not completed. 

What has to be done to enable the completion of the 3-hand shake?

Thank you


For Issue#1;

Please check "user identification" is enabled on the zones which are associated to those VLANs.

For Issue#2;

You need to check Routing and NAT rules to make sure whether it is done properly.

If config on either issues looks fine, you can contact support.

Hi Snisar,

Thanks for the information.  User-Identification has been checked for all the required zones.  I think there is something wrong the way I have configured the NAT and Security rule.  Will look into it shortly.

I will be looking into changing the route and NAT policy that is in place.  What is confusing me is would this require configuring a Layer 2 network again for any specific physical interface?  I was thinking on this because, I have gone through a document which helps configuring a Layer 2 to Layer 3 on the PAN Device.

Any thoughts?

Kind Regards,


All sorted out.  It had no issues with NAT or Routing rules ( was very confusing looking into specially when you 68 NAT rules).  What all I did was adding the 172.X.X.X network in the Allow List of the User-ID agent and creating a new sub-interface.

Thanks for your concern.
