I need to configure native on DGS-3100 48
The DGS-3100 series supports IEEE 802.1Q VLANs.
The switch's default is to assign all ports to a single 802.1Q VLAN named default. The default VLAN has a VID = 1.
If a port is configured with Tagging enabled, then incoming frames that come with a tag will be untouched and will maintain its VID, but if they come untagged then it will put a VID number.
This port will be a "trunk port" (capable of receiving tagged traffic from one or more VLANs).
For more details, here is the configuration manual (Tagging and untagging, page 68).
but if they come untagged then it will put a VID number
. I think that's is the key to solve your problem.
Normaly a port can only be a member of one untagged VLAN. Dlink however has a feature documented in the manual called "Asymetric VLAN" that allows multiple VLANS to be untagged on the same port. This allows multipple VLANS to access the same server but not eachother. This feature needs to be enabled for it to be possible to untag multipple VLANS on the same port. From the manual:
Port 1 connect to Server; port 1, port 3, port 9 and port 17 are untagged ports; PC3 & PC4 are in the same VLAN#3; port 1
is a untagged member of VLAN#2 and VLAN#3 (untagged member overlap). Then the server can talk with VLAN#2,
VLAN#3; PC3 and PC4 can talk to the server and to each ot
her; PC2 can talk to the Se
rver; VLAN#2 can’t communicate
with VLAN3.
In this example port 1 need to be untagged member in VLAN#2 & VLAN#3, so Asymmetric VLAN should be enabled
