VLAN question on DGS-1100-08
« on: April 04, 2016, 04:23:09 AM »

Hi all

Since this is the only place I found something about the DGS-1100-08, I'll post here as well. My question is about VLAN in general though.

After reading posts on this forum, I'm still not 100% sure if I understood the terms of "tagged, untagged, not member" correctly.

I have 3 switches now, all DGS-1100-08. The setup is somewhat complicated, but here is simple example to show my questions:



Red is one VLAN, blue in another. Both need to be transported between the switches. So I configure 3 VLANs. VLAN 1 is default. VLAN 2 = blue, VLAN 3 = red.

What is the correct configuration for ports 1-8 in each VLAN?
Are ports 1-4 untagged in VLAN 2 and VLAN 3 ? Or "not member" ? What about VLAN 1 ?
Ports 5 + 7 are "tagged" in VLAN 3, but "not member" in VLAN 1 and VLAN 2 ?

I'm confused  ???

Thanks a lot
Patrick

Hi,

in your scenario any of your switches has at least one port (left: port 4, middle: ports 1 and 2, right: port 3), that has to transmit more than one VLAN (namely VLAN 2 (blue) and VLAN 3 (red)).

In general if a switch has at least one port to be used with at least two VLANs, you have to:

- Disable Port-Based VLAN
- Enable 802.1Q VLAN

In your case you have to do so for all three switches.

Then:

For the left switch:
- Add a new VLAN 2 (blue) and set port 4 to "Tagged" and port 6 to "Untagged" (leave alle other ports in state "Not Member")
- Add a new VLAN 3 (red) and set port 4 to "Tagged" and port 5 to "Untagged" (leave alle other ports in state "Not Member")
- The already existing VLAN 1 should now have ports 1-4 and 7-8 in state "Untagged" and ports 5-6 in state "Not Member"
- in PVID settings set ports 1-8 to the following PVID values: 1, 1, 1, 1, 3, 2, 1, 1

For the switch in the middle:
- Add a new VLAN 2 (blue) and set ports 1 and 2 to "Tagged" (leave alle other ports in state "Not Member")
- Add a new VLAN 3 (red) and set ports 1 and 2 to "Tagged" (leave alle other ports in state "Not Member")
- The already existing VLAN 1 should now still have all ports 1-8 in state "Untagged".
- in PVID settings set ports 1-8 to the following PVID values: 1, 1, 1, 1, 1, 1, 1, 1

For the right switch:
- Add a new VLAN 2 (blue) and set port 3 to "Tagged" and port 8 to "Untagged" (leave alle other ports in state "Not Member")
- Add a new VLAN 3 (red) and set port 3 to "Tagged" and port 7 to "Untagged" (leave alle other ports in state "Not Member")
- The already existing VLAN 1 should now have ports 1-6 in state "Untagged" and ports 7-8 in state "Not Member"
- in PVID settings set ports 1-8 to the following PVID values: 1, 1, 1, 1, 1, 1, 3, 2

As a result only the devices in the same VLAN (2 or 3) can talk to each other. All devices connected to other ports are assigned to VLAN 1 and can only talk to each other but not to devices belonging to VLANs 2 or 3. The switch management address is only accessible via a switch port assigned to VLAN 1.

If you want to add one of the other ports of any of the three switches to VLAN 2 or VLAN 3, you have to
- Edit the VLAN X (X=2 or 3 respectively) and set the desired port to "Untagged"
- Set the PVID value (in PVID settings) of the desired port to X (X=2 or 3 respectively).

Some basics:
- The PVID value of a port identifies the VLAN that untagged frames entering the port ("receiving direction") will be assigned.
- In the "sending direction" a frame belonging to VLAN X is sent untagged on port Y, if port Y is configured "Untagged" for VLAN X.
- Note: Any port can be configured "Untagged" for at most one VLAN only.
- A port that is configured "Untagged" or "Not Member" for a VLAN X, can be configured "Tagged" for any number of VLANs other than X.

Wow!  ;D ;D
Thank you so much for the detailed answer. I will try everything later this week and report back if everything worked as expected.

Hello PT

I finally found the time to test it. With your detailed answers, I was able to configure everything correctly now. Thanks again!

I'll try to summarize to see if I understood correctly:
Tagged: Frames are already tagged for this VLAN, don't do anything.
Untagged: If a frame belongs to VLAN A and the port is configured as "untagged" for VLAN A, the VLAN Tag is removed by the switch
Not Member: The port doesn't belong to the VLAN and mustn't see any frames meant for this VLAN
PVID: Frames will be tagged with the given VLAN number. This is only true, if the frames are not tagged already.

Cheers
Patrick

Hi Patrick,

Tagged: Frames are already tagged for this VLAN, don't do anything.
Untagged: If a frame belongs to VLAN A and the port is configured as "untagged" for VLAN A, the VLAN Tag is removed by the switch
Not Member: The port doesn't belong to the VLAN and mustn't see any frames meant for this VLAN
PVID: Frames will be tagged with the given VLAN number. This is only true, if the frames are not tagged already.

Correct! Perhaps one additionial remark: "Untagged" is meant for frames leaving the switch, while PVID refers to frames entering the switch. This differentiation seems to be specific for D-Link switches (and other vendors don't use this, e.g. Cisco). It does not make much sense for me, because I don't know any scenario (other than academic ones), where I should have to configure two different values for "PVID" and "Untagged" for a given port.

Exactly, that's why I didn't really get the meaning of PVID first. Well, as long as it works now  ;D

what firmware version is this? I have a DGS-1100-16, and my setup doesn't have anything like PVIDs.

I have::

VLAN Mode    
Acceptable Frame    
Ingress Checking    
VID(1-4094)    
Action    
Allowed VLAN Range

I really wish DLINK had some practical examples of how to set up a vlan.  I can do it by hand in OpenWRT but DLINK's way just leaves me stumped.

Looks like Patrick's DGS-1100-08 is hardware version A1 (REVA) with latest firmware version being V1.10.016 and latest manual being version 1.04 (dated 11-13-2013), while your device is hardware version B1 or B2 (REVB). For your model the latest firmware is V.1.01.018 and the GUI, and also how to configure VLANs is different from REVA as described in this manual.
