VLAN 802.1Q Not working as expected.

Model: ER7212PC  
Hardware Version: V2
Firmware Version: Latest

Hello, I am struggling with VLAN setup on this tplink device. 

I am with experience in Corporate LAN networks so 802.1Q VLAN is well known at my end.

 

Expected results:

VLAN 2 Office

- Interface

-Default VLAN

-VLAN number 2(changed to 2) 

Unagged ports 5-10(PVID) 

Tagged ports 11-12

Selected ininterface options ports 5-12, confugired on device as PVID for ports 5-10

 

 

- VLAN  VMware Vmotion

- configured as VLAN so tagged on all pprts

- VLAN Number 5

 

- VLAN Management

- Interface

- VLAN number 4

Untagged ports 11-12

Selected Interface options porrs 11-12, configured on device PVID on ports 11-12

 

 

The issue is that VLAN 2 is not tagged on ports 11-12. ( at least not communicatng as there is no way of checking what is actually tagged) I Have connected Hypervisor for Office VM's on ports 11-12 and tp-link does not provide connectivity. This is observed as bug in device operations. Vlan 5 works fine on Hypervisor devices as tagged VLAN. 

Hours wasted troubleshooting waiting for support telephone pickup so basically no telephone support available. 

Kindly provide solution how to make default vlan untagged for PVID and tagged on specified ports. 

Any support how to see cli config to see if this is actually seen as tagged also welcome. 

 

 

Of course verified docs and this VLAN config seems to be supported.  But not working as advertised.

Hi @Lucek,

 

Not sure you should trunk the default VLAN.  If you need to trunk VLAN 2, just don't make it the default VLAN.

Have you actually assigned all the vlans to all the ports in the lan settings ?

 

If you adjust the port to a native PVID, it will be untagged port on that PVID, all others will be tagged.  If a vlan isnt assigned to a port, it wont be there in any form.

 

If you go to each port on the unit and look in the PVID list, you should see them all - that is how you can double check a vlan is assigned to that port or not

Why i cannot use default vlan as trunk? 

Documentation linked on vendor page clearly says that VLAN(and Interface) that is not set as PVID will be tagged. 

 

Yes I have double and triple checked that Interface config  have correct port selected. 

In GUI config looks fine. This looks like a Bug in software.

 

I cannot make successful ping communication to gateway while my VM is assigned to VLAN 2, 

How to deal with support and get this bug resolved since no phone is picked and no emails are replied placed in web support form? 

Is there any way to place official TAC ticket other than this forum? 

I am happy to provide any technical details that will help vendor to resolve this bug.
