Is my upgrade the cause of a vlan not working

L4 Transporter

After I upgraded my palo alto fro 7.1.15 to 7.1.16 I had a report that a certain vlan can not longer access the internet.  I have a back up of the config before the upgrade and one after the upgrade and so far I don't see any change in virtual routers that would have cause the PA to block the traffic. I know that is very little information but if anyone has any suggestions I would appreciate it

@jdprovine,

While it wouldn't be impossible to see an update cause an issue with the configuration that may cause an issue like this, it would be abnormal. Looking at your logs to you see the traffic trying to come across the firewall or can you not even see the traffic? 

@BPry

There is absolutely no traffic from that vlan showing on the firewall at all. 

@jdprovine,

I'd try to take a PCAP and see if the firewall simply isn't reporting the traffic. Past that I don't think an update would be able to cause this sort of situation short of it somehow managing to 'disable' the port. 

@BPry

I ran a continuous ping to the gateway in the vlan while I ran pcaps with the filter of my pc IP and the gateway IP. The only thing I saw was "no response found"
