Hi,

I have a D-Link DIR-890L gigabit router running DD-WRT v3.0-r44483.I am trying to setup 802.1q VLANs with a trunk between the DIR-890L port labeled 4 to port 1 on a managed switch in the attic, a D-Link DGS-1100-08. But it isn't working for me.


Here is what I have done.
I figured I'd use the default vlan1 on the router (DD-WRT) for normal LAN traffic and an additional vlan10 for the kids LAN traffic. And naturally vlan2 for the default WAN side of the router.

This is the vlan configuration of the attic switch:


I have a hard time understanding which ports are which on the DIR-890L router. As far as I can tell there are the physical labels on the back of the router, then different numbers are used for the WebUI (Switch Config page) and other numbers for the vlan.*ports nvram fields and finally slightly other numbers for the port.*vlans nvram fields. For some info on that have a look here https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=326905. This topic also has the initial nvram fields before I made any modifications.

Anyway. I decided to disregard the WebUI ports and go with the physical labels on the back of the router and the nvram fields. From the link above I got the tip that port.*vlans nvram fields are used for WebUI config and not used by the switch logic, but I tried to set them anyway. For the vlan.*ports fields I took inspiration from the '802.1q VLAN trunk' section on the Switched Ports page (https://wiki.dd-wrt.com/wiki/index.php/Switched_Ports#802.1q_VLAN_trunk)

Here is what I currently have for the nvram variables:

An update on this in case it helps somebody in the future. I got it working.

In summary the DIR-890L port labelled 4 is trunked to my attic managed switch port labelled 1. The trunk carries vlan1 and vlan10. The attic switch is configured as in the previous post on this topic.

I made various trials (and errors), and during the process I flashed v3.0-r44340 which RageX mentioned in this post:
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=288225&postdays=0&postorder=asc&start=90
.. although I am not sure that was actually necessary.

I ended up with this port mapping of the DIR-890L ports:
Physical Port Label | WebUI Port | port.*vlans | vlan.*ports
1 | 4 | 4 | 0
2 | 3 | 3 | 1
3 | 2 | 2 | 2
4 | 1 | 1 | 3
WAN | W | 0 | 4
----
CPU | - | 5 | 5

For setting up the vlans described above I used the WebUI (after all) to set some Switch Config properties:

.. also not sure if this was actually needed or not (I was trying stuff out)..

I changed some of the nvram settings by hand so they look as follows:
