GS308T VLAN 802.1Q Tags missing in Egress from switch
I have a GS308T switch connected to two test hosts and a management device assd shown in the diagram. Port 5 is connected to Test Host 1, which is set to VLAN-tag all frames for VLAN ID 102. Port...
The issue was that windows removed VLAN tags from incoming packets before handing them to VMs.
The switch is fine, I just made the mistake of assuming that virtualization would bypass the VM Host's network stack.
Test host 1 is on g5 and using tagged frames for VLAN 101 and 102?
Test host 2 is on g3 for VLAN 101, respectively g6 for VLAN 102?
g3 is not connected to anything, but Test Host 2 is on g6.
g5 (Test Host 1) is tagged on 101,102
- Test Host 1 is configured to transmit tagged frames
g6 (Test Host 2) is untagged on 102
- Test Host 2 expects/transmits untagged frames
Here's the table (since images aren't working in the post).
| Interface | PVID | VLAN member | VLAN Tag | Acceptable Frame | Ingress Filtering | Current Ingress Filtering | Untagged VLANs | Tagged VLANs | Forbidden VLANs | Dynamic VLANs | Port Priority |

| g2 | 1 | 1 | None | Admit All | Enable | Enable | 1 | None | None | None | 0 |
| g3 | 101 | 101 | None | Admit Untagged Only | Enable | Enable | 101 | None | None | None | 0 |
| g4 | 1 | 1 | None | Admit All | Enable | Enable | 1 | None | None | None | 0 |
| g5 | 1 | 101-102 | 101-102 | VLAN Only | Enable | Enable | None | 101-102 | None | None | 0 |
| g6 | 102 | 102 | None | Admit Untagged Only | Enable | Enable | 102 | None | None | None | 0 |
