Tagging not working after upgrade
Hello everybody,
Im running 2 VE on Hyper-V(prod and test). TEST is at version 14.1.2.1 and PROD at 12.1.4.1. Last week I tried to upgrade also PROD to version 14.1.2.1 but problem with traffic occured. After some time of investigation I found out that problem is with tagged vlan interfaces. For example - untagged communication via interface 1.1 works fine; tagged communication via interface 1.1 doesnot work. I did some tests(tcpdump) and found out that If some device in same segment tried to ping tagged interface of my F5 so I can see ARP for that traffic at F5. I also can see that F5 sends reply for that ARP but unfortunately this information is not delivered to hosts who pinged. It seems like outgoing communication from F5 is somewhere dropped. Sure, it points to Hyper-V but it worked before upgrade. I also checked release notes to my version and no related information
Can someone advice?
thank you
Martin
